Description
Technical Field
The present invention relates to the field of virtual machines, and in particular, to a data sharing method and apparatus for dual systems based on data isolation, and a terminal device.
Background
Taking an Android mobile phone as an example, the same mobile phone user may log in different user management systems by using the mobile phone, different authority limits exist in different user management systems, and the corresponding same user has different roles, for example, the same user is used as a host for daily use, can only access limited applications as a visitor, and the use functions defined by different users are different or different access authorities need to be set. Therefore, the same mobile phone needs to be adapted according to different user requirements, and executable functions, received data, requirements on security, access to public and private networks and the like in a host mode/visitor mode are all different, so that it is generally expected that the data can be isolated from each other under various user use scenes so as to increase security.
The CN110245001A data isolation method and device and the electronic equipment propose a data isolation method, wherein a virtual machine manager is carried on a terminal device, a user operating system running on a first virtual machine and a trusted execution environment running on a second virtual machine. According to the scheme, different virtual machines are adopted to adapt to different user requirements, and the two virtual machines have independent data spaces, so that the data isolation degree is high.
However, the attribute configuration (such as brightness setting, text size, etc.) of the same mobile phone is generally expected to be the same for the same user regardless of the user role, but the above scheme has a problem that the attribute configuration modified by the user cannot be inherited when the virtual machine is switched. Taking the following scenario as an example, assuming that the default font size of the system is "medium", the user prefers a large font, and when the user operates the virtual machine 1 as a host, the setting of the font size is modified to be "large"; however, when the virtual machine 2 is switched from the virtual machine 1, the virtual machine manager is re-initialized, the font size setting is restored to the default configuration of the virtual machine 2, namely, the default configuration of the system ("medium"), and the modification setting of the user when the virtual machine 1 is operated is not inherited, so that the user has to modify again, and the user experience is poor.

Detailed Description
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following description will explain the specific embodiments of the present invention with reference to the accompanying drawings. It is evident that the drawings in the following description are only examples of the invention, from which other drawings and other embodiments can be obtained by a person skilled in the art without inventive effort.
For the sake of simplicity of the drawing, the parts relevant to the present invention are shown only schematically in the figures, which do not represent the actual structure thereof as a product. Additionally, in order to facilitate a concise understanding of the drawings, components having the same structure or function in some of the drawings are only schematically depicted, or only one of them is labeled. Herein, "a" means not only "only this one" but also "more than one" case.
In one embodiment of the present invention, as shown in fig. 1, a data sharing method of a dual system based on data isolation includes:
step S100, mounting points are set on terminal equipment, and public configuration information is recorded by the mounting points;
step S200, when switching from the first virtual machine to the second virtual machine, updating the public configuration information of the mounting point according to the current configuration information of the first virtual machine, and then exiting the first virtual machine;
step S300, before starting the second virtual machine, obtaining public configuration information of mounting points;
step S400 sets the terminal device according to the common configuration information, and updates the configuration information of the second virtual machine according to the common configuration information.
Specifically, a dual-system scheme of data isolation, i.e. two virtual machines, is configured on the terminal equipment (such as an Android mobile phone). Since two virtual machines have independent data spaces, they have independent configuration files.
The configuration content of both configuration files may be the same, for example, both are initial configuration of the system. But each user has its own preferences and the user modifies the configuration on the virtual machine running in the foreground (or on the virtual machine currently running), such as on the first virtual machine, which configuration, when saved, is saved in the configuration file of the first virtual machine. When switching from the first virtual machine to the second virtual machine, since the configuration modified on the first virtual machine is not shared to the second virtual machine, with the exit of the first virtual machine, the setting of the terminal device is switched to the configuration set by the configuration file of the second virtual machine, i.e. is restored to the system initial configuration again. In order to enable the modified configuration on the first virtual machine to be shared to the second virtual machine, a mounting point is set on the terminal device, setting information which all virtual machines must inherit and keep consistent is taken as common configuration information, and the common configuration information is stored at the mounting point.
The mount point is independent of all virtual machines, and does not belong to any virtual machine, and can be regarded as an independent storage file system. The mounting point belongs to a shared data area, and each virtual machine can be accessed. If the mount point is set in the virtual machine, the problem of data sharing between the virtual machines still cannot be solved, and the mount point on the virtual machine is recovered along with the exit of the virtual machine.
When the virtual machine is switched, for example, the first virtual machine is switched to the second virtual machine, and when the virtual machine manager controls the first virtual machine to exit, the public configuration information of the mounting point is updated according to the current configuration information of the first virtual machine, and then the first virtual machine is exited; when the second virtual machine is controlled to be started, public configuration information of the mounting point is obtained first, then the configuration information of the second virtual machine is updated according to the public configuration information, and then the second virtual machine is started. The reverse virtual machine switch, the process is similar. In this way, the latest common configuration information is shared among the virtual machines. The latest common configuration information can be inherited no matter which virtual machine is cut to. The user only needs to modify once, and the modified configuration information is inherited, so that the user experience is improved.
Optionally, when switching from the first virtual machine to the second virtual machine and controlling the first virtual machine to exit, firstly acquiring public configuration information from a file system of the mounting point; and comparing the obtained public configuration information with corresponding items in the current configuration information of the first virtual machine, and if the two types of public configuration information are completely consistent, updating the public configuration information of the mounting point according to the current configuration information of the first virtual machine is not needed, so that the write operation of the system can be reduced, the load of the mounting point is lightened, and the performance of the Android system is improved.
The common configuration information may be general property settings under the mobile phone settings, such as display and brightness, font size, wallpaper, sound, etc., which affect the user's experience of use, including but not limited to these. Preferably, the setting information related to the mobile phone hardware device is used as public configuration information, so that the hardware device on the mobile phone can be always in a stable state, unnecessary fluctuation of the hardware device is avoided when the virtual machine is switched, and the reliability of the hardware device is improved. Optionally, the public configuration information of the mounting points is customized according to the needs of the user. The public configuration information of the mounting point can be only configuration data concerned by a user, possibly part of the content in the configuration information of the virtual machine, so that the memory occupied by the mounting point can be further reduced.
In the prior art, when the first virtual machine is exited and the second virtual machine is not started yet, the virtual machine manager has an initialization process to return the setting of the terminal device to the initial state of the system, and then, along with the start of the second virtual machine, the setting of the terminal device is cut to the configuration of the second virtual machine, so that the problem of unsmooth configuration exists in the virtual machine switching process.
In this embodiment, when the second virtual machine is controlled to be started and the public configuration information of the mounting point is obtained, the virtual machine manager updates the configuration information of the second virtual machine according to the public configuration information, sets the terminal device according to the public configuration information, and then starts the second virtual machine. Through the operation, when the first virtual machine is withdrawn and the second virtual machine is not started, the setting of the terminal equipment corresponding to the public configuration information is consistent with the setting of the first virtual machine and the setting of the second virtual machine, the setting is smooth in the switching of the virtual machines, the seamless switching is realized, and the user experience is improved.
According to the embodiment, the sharing and inheritance of the latest public configuration information among the virtual machines are realized through the latest public configuration information of the mounting point; by setting the terminal equipment according to the latest public configuration information in the virtual machine switching process, seamless switching between virtual machines is realized, and user experience is better.
In another embodiment of the present invention, as shown in fig. 2, a data sharing method of a dual system based on data isolation includes:
step S110, mounting points are arranged on terminal equipment, and the mounting points record public configuration information and special configuration information of each virtual machine;
step S210, when switching from the first virtual machine to the second virtual machine, updating public configuration information recorded by the mounting point and special configuration information of the first virtual machine according to the current configuration information of the first virtual machine, and then exiting the first virtual machine;
step S310, before starting the second virtual machine, obtaining public configuration information of the mounting point and special configuration information of the second virtual machine;
step S410 sets the terminal device according to the common configuration information and the special configuration information of the second virtual machine, and updates the configuration information of the second virtual machine according to the common configuration information.
Specifically, the mounting point records special configuration information of each virtual machine in addition to common configuration information. The common configuration information is to configure the same attribute for each virtual machine, and the special configuration information configures different attributes for each virtual machine. The network connection configuration of each virtual machine to the mobile phone may be different, for example, the network channel of the first virtual machine is adapted to the public network, and a wireless local area network WIFI can be opened; the network channel of the second virtual machine is adapted to a private network, such as a army, a government enterprise, etc., and requires opening a VPN.
The special configuration information may be stored in the form of separate files for each virtual machine.
In the prior art, the problem that the special configuration information is not smooth in recovery when the virtual machine is switched exists. For example, the setting of the wireless local area network, the setting of the first virtual machine is assumed to close the WLAN function of the wireless local area network, the setting of the second virtual machine is assumed to open the WLAN function of the wireless local area network, and the initial state of the system is assumed to close the WLAN function; switching from the first virtual machine to the second virtual machine, wherein the virtual machine manager has an initialization process in the switching process, so that the setting of the terminal equipment is returned to the initial state of the system, and the WLAN function is closed; then, along with the starting of the second virtual machine, the WLAN function is restored to be started when the terminal equipment is set according to the configuration information of the second virtual machine; the user can feel that the network connection configuration is not smooth during the virtual machine switching process.
In order to solve the problems, the special configuration information is restored more smoothly, and before the virtual machine exits, the public configuration information of the mounting point is updated according to the current setting condition of the virtual machine to be exited, and the special configuration information of the corresponding virtual machine recorded by the mounting point is updated; before restarting the virtual machine, not only acquiring public configuration information from the mounting point, but also acquiring special configuration information of the virtual machine; the terminal equipment is set according to the public configuration information and the special configuration information of the virtual machine, so that the latest public configuration information can be continued, the special configuration information of the second virtual machine can be recovered as soon as possible, and a user can feel faster switching time delay between the virtual machines than the prior art.
For example, if the backlight levels of the virtual machine 1 and the virtual machine 2 are expected to be consistent by the user and the WIFI settings of the virtual machine 1 and the virtual machine 2 are different, the backlight level is set as the common configuration information of the mounting point, and the WIFI is set as the special configuration information of the mounting point; through the scheme, the user's expectations can be better met.
Compared with the virtual machine, the mounting point only stores the configuration data concerned by the user, so that the memory occupied by the mounting point is smaller. If the mounting point is realized by adopting the third virtual machine, the occupied memory is larger, and the third virtual machine needs to reside in the memory, so that the system performance of the mobile phone is reduced. In addition, the mounting point is interacted with only at the moment of switching the virtual machine, so that the mounting point does not need to reside in a system memory generally, and larger system overhead and the usability of the Android mobile phone cannot be influenced by the addition of the mounting point.
According to the embodiment, the public configuration information and the special configuration information of each virtual machine are recorded at the mounting point, so that the latest public configuration information can be well inherited and synchronized when the virtual machines are switched, meanwhile, the special configuration information of each virtual machine can be recovered, a user cannot feel the influence of the switching of the virtual machines, and the experience is better.
In one embodiment of the present invention, as shown in fig. 3, a dual system data sharing apparatus 100 based on data isolation includes:
a mounting point setting module 110, configured to set a mounting point on the terminal device, where the mounting point records public configuration information;
a configuration information updating module 140, configured to update common configuration information of the mounting point according to current configuration information of the first virtual machine when switching from the first virtual machine to the second virtual machine, and then exit the first virtual machine;
a configuration information obtaining module 120, configured to obtain common configuration information of the mounting point before the second virtual machine is started;
a configuration information sharing module 130, configured to update configuration information of the second virtual machine according to the common configuration information;
and the configuration information implementation module 150 is configured to set the terminal device according to the common configuration information.
Specifically, a dual-system scheme of data isolation, i.e. two virtual machines, is configured on the terminal equipment (such as an Android mobile phone). Since two virtual machines have independent data spaces, they have independent configuration files.
The configuration content of both configuration files may be the same, for example, both are initial configuration of the system. But each user has its own preferences and the user modifies the configuration on the virtual machine running in the foreground (or on the virtual machine currently running), such as on the first virtual machine, which configuration, when saved, is saved in the configuration file of the first virtual machine. When switching from the first virtual machine to the second virtual machine, since the configuration modified on the first virtual machine is not shared to the second virtual machine, with the exit of the first virtual machine, the setting of the terminal device is switched to the configuration set by the configuration file of the second virtual machine, i.e. is restored to the system initial configuration again. In order to enable the modified configuration on the first virtual machine to be shared to the second virtual machine, a mounting point is set on the terminal device, setting information which all virtual machines must inherit and keep consistent is taken as common configuration information, and the common configuration information is stored at the mounting point.
The mount point is independent of all virtual machines, and does not belong to any virtual machine, and can be regarded as an independent storage file system. The mounting point belongs to a shared data area, and each virtual machine can be accessed. If the mount point is set in the virtual machine, the problem of data sharing between the virtual machines still cannot be solved, and the mount point on the virtual machine is recovered along with the exit of the virtual machine.
When the virtual machine is switched, for example, the first virtual machine is switched to the second virtual machine, and when the virtual machine manager controls the first virtual machine to exit, the public configuration information of the mounting point is updated according to the current configuration information of the first virtual machine, and then the first virtual machine is exited; when the second virtual machine is controlled to be started, public configuration information of the mounting point is obtained first, then the configuration information of the second virtual machine is updated according to the public configuration information, and then the second virtual machine is started. The reverse virtual machine switch, the process is similar. In this way, the latest common configuration information is shared among the virtual machines. The latest common configuration information can be inherited no matter which virtual machine is cut to. The user only needs to modify once, and the modified configuration information is inherited, so that the user experience is improved.
Optionally, when switching from the first virtual machine to the second virtual machine and controlling the first virtual machine to exit, firstly acquiring public configuration information from a file system of the mounting point; and comparing the obtained public configuration information with corresponding items in the current configuration information of the first virtual machine, and if the two types of public configuration information are completely consistent, updating the public configuration information of the mounting point according to the current configuration information of the first virtual machine is not needed, so that the write operation of the system can be reduced, the load of the mounting point is lightened, and the performance of the Android system is improved.
The common configuration information may be general property settings under the mobile phone settings, such as display and brightness, font size, wallpaper, sound, etc., which affect the user's experience of use, including but not limited to these. Preferably, the setting information related to the mobile phone hardware device is used as public configuration information, so that the hardware device on the mobile phone can be always in a stable state, unnecessary fluctuation of the hardware device is avoided when the virtual machine is switched, and the reliability of the hardware device is improved. Optionally, the public configuration information of the mounting points is customized according to the needs of the user. The public configuration information of the mounting point can be only configuration data concerned by a user, possibly part of the content in the configuration information of the virtual machine, so that the memory occupied by the mounting point can be further reduced.
In the prior art, when the first virtual machine is exited and the second virtual machine is not started yet, the virtual machine manager has an initialization process to return the setting of the terminal device to the initial state of the system, and then, along with the start of the second virtual machine, the setting of the terminal device is cut to the configuration of the second virtual machine, so that the problem of unsmooth configuration exists in the virtual machine switching process.
In this embodiment, when the second virtual machine is controlled to be started and the public configuration information of the mounting point is obtained, the virtual machine manager updates the configuration information of the second virtual machine according to the public configuration information, sets the terminal device according to the public configuration information, and then starts the second virtual machine. Through the operation, when the first virtual machine is withdrawn and the second virtual machine is not started, the setting of the terminal equipment corresponding to the public configuration information is consistent with the setting of the first virtual machine and the setting of the second virtual machine, the setting is smooth in the switching of the virtual machines, the seamless switching is realized, and the user experience is improved.
According to the embodiment, the sharing and inheritance of the latest public configuration information among the virtual machines are realized through the latest public configuration information of the mounting point; by setting the terminal equipment according to the latest public configuration information in the virtual machine switching process, seamless switching between virtual machines is realized, and user experience is better.

the configuration information implementation module 150 is configured to set the terminal device according to the common configuration information and the special configuration information of the second virtual machine.
Specifically, the mounting point records special configuration information of each virtual machine in addition to common configuration information. The common configuration information is to require each virtual machine to configure the same attribute, and the special configuration information configures different attributes for each virtual machine. The general attribute configuration of each virtual machine to the mobile phone may be the same, but the network connection configuration may be different, for example, the network channel of the first virtual machine is adapted to the public network, and may open a wireless local area network WIFI and the like; the network channel of the second virtual machine is adapted to a private network, such as a army, a government enterprise, etc., and requires opening a VPN.
The special configuration information may be stored in the form of separate files for each virtual file.
In the prior art, the problem that the special configuration information is not smooth in recovery when the virtual machine is switched exists. For example, the setting of the wireless local area network, the setting of the first virtual machine is assumed to close the WLAN function of the wireless local area network, the setting of the second virtual machine is assumed to open the WLAN function of the wireless local area network, and the initial state of the system is assumed to close the WLAN function; switching from the first virtual machine to the second virtual machine, wherein the virtual machine manager has an initialization process in the switching process, so that the setting of the terminal equipment is returned to the initial state of the system, and the WLAN function is closed; then, along with the starting of the second virtual machine, the WLAN function is restored to be started when the terminal equipment is set according to the configuration information of the second virtual machine; the user can feel that the network connection configuration is not smooth during the virtual machine switching process.
In order to solve the problems, the special configuration information is restored more smoothly, and before the virtual machine exits, the public configuration information of the mounting point is updated according to the current setting condition of the virtual machine to be exited, and the special configuration information of the corresponding virtual machine recorded by the mounting point is updated; before restarting the virtual machine, not only acquiring public configuration information from the mounting point, but also acquiring special configuration information of the virtual machine; the terminal equipment is set according to the public configuration information and the special configuration information of the virtual machine, so that the latest public configuration information can be continued, the special configuration information of the second virtual machine can be recovered as soon as possible, and a user can feel faster switching time delay between the virtual machines than the prior art.
For example, if the backlight levels of the virtual machine 1 and the virtual machine 2 are expected to be consistent by the user and the WIFI settings of the virtual machine 1 and the virtual machine 2 are different, the backlight level is set as the common configuration information of the mounting point, and the WIFI is set as the special configuration information of the mounting point; through the scheme, the user's expectations can be better met.
Compared with the virtual machine, the mounting point only stores the configuration data concerned by the user, so that the memory occupied by the mounting point is smaller. If the mounting point is realized by adopting the third virtual machine, the occupied memory is larger, and the third virtual machine needs to reside in the memory, so that the system performance of the mobile phone is reduced. In addition, the mounting point is interacted with only at the moment of switching the virtual machine, so that the mounting point does not need to reside in a system memory generally, and larger system overhead and the usability of the Android mobile phone cannot be influenced by the addition of the mounting point.
According to the embodiment, the public configuration information and the special configuration information of each virtual machine are recorded at the mounting point, so that the latest public configuration information can be well inherited and synchronized when the virtual machines are switched, meanwhile, the special configuration information of each virtual machine can be recovered, a user cannot feel the influence of the switching of the virtual machines, and the experience is better.
