Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with specific embodiment, and reference
The embodiment of the present invention is further described in attached drawing.
It should be noted that all statements for using " first " and " second " are for differentiation two in the embodiment of the present invention
The non-equal entity of a same names or non-equal parameter, it is seen that " first " " second " only for the convenience of statement, does not answer
It is interpreted as the restriction to the embodiment of the present invention, subsequent embodiment no longer illustrates this one by one.
It should be noted that in an embodiment of the present invention, openstack is that a kind of cloud computing manages platform, libvirt
For a kind of Virtual Machine Manager tool.
According to an aspect of the present invention, a kind of method that the embodiment of the present invention proposes Virtual Machine Manager USB device, such as
May include step shown in Fig. 1: S1 obtains the information of virtual machine and the letter for the USB device being mounted on the virtual machine
Breath；The information of the virtual machine is associated with by S2 in the database with the information of the corresponding USB device；S3, in response to receiving
To the instruction for restarting the virtual machine, the database is inquired to obtain the information of the corresponding USB device of the virtual machine；
The USB device is mounted to the virtual machine after restarting according to the information of the corresponding USB device by S4 again.
Method disclosed by the invention passes through the information and corresponding virtual machine letter for the USB device that will be mounted on virtual machine
Breath is associated in the database, when carrying out virtual machine and restarting, corresponding information can be inquired, to obtain virtual machine carry
USB device, and then the USB device that front mount is restarted in virtual machine continuation is mounted on virtual machine again.
Below with reference to Fig. 2 shows the flow diagram of method of Virtual Machine Manager USB device be described in detail.
Firstly, it is necessary to obtain the information of the virtual machine and the information for the USB device being mounted on the virtual machine.
It should be noted that the information of the USB device being mounted on the virtual machine obtained is successfully to have hung
It is downloaded to the information of the USB device on virtual machine, for example, can pass through after user starts virtual machine by virtual machine management platform
USB list selects to give the virtual machine carry which USB device, and by these USB device carries on a virtual machine after, obtain these
The information of USB device.Or it can also be that user reselects the information for needing to be mounted to the USB device on virtual machine.
In some embodiments, the information of virtual machine can be the ID of virtual machine, and the information of USB device can be USB and set
Standby product IDs and vendor id.
Then, by the information of the virtual machine and the information preservation of the corresponding USB device to database and in data
It is associated in library.
In some embodiments, the mapping table of virtual machine with corresponding USB device can be established in the database, then will
The product IDs and vendor id of the ID of the virtual machine and the corresponding USB device are added in the mapping table, and record more
The new time.
Specifically, can create the table of a virtual machine carry USB device in nova_api database, essential record is empty
The map information of quasi- machine and USB device, and a series of interfaces such as increase, modification, inquiry are provided to nova to operate the table, such as
Say carry USB success after, create interface can be called to create a record in the table, can also by query interface according to
Virtual machine ID inquires the USB device list of carry on virtual machine.The interaction of nova and libvirt is mainly libvirt externally sudden and violent
The api of dew is realized.
Through the above steps, the mapping relations between virtual machine and corresponding USB device are had recorded, if subsequent to void
Quasi- machine carries out reboot operation, can by inquiring the virtual machine which USB device of carry before restarting can be obtained in mapping table,
And these USB devices of carry again.
Then, the instruction that the virtual machine is restarted in response to receiving inquires the database to obtain the virtual machine
The information of the corresponding USB device.
In some embodiments, it can be inquired according to the ID of virtual machine and obtain the corresponding USB in the mapping table
The product IDs and vendor id of equipment.
Finally, the USB device to be mounted to the void after restarting again according to the information of the corresponding USB device
Quasi- machine.
In some embodiments, the information for the corresponding USB device that will acquire is added to the virtual machine and restarts
When the configuration file that loads in.Then XML file is generated according to the configuration file, the XML file is finally sent to void
Quasi- machine management tool, to restart the virtual machine.
Specifically, OpenStack has a loaded virtual machine to configure before calling libvirt driver to restart virtual machine
The operation of information inquires database by virtual machine ID when loaded virtual machine configuration, finds the USB of carry on virtual machine
Then the USB device information of virtual machine is added in virtual machine configuration, is then generated according to configuration file by facility information
Xml document is issued libvirt starting virtual machine by xml document.
In some embodiments, the instruction for deleting the virtual machine is received, corresponding delete is recorded in the mapping table
Except the time, and modify deleted marker position.
It should be noted that virtual machine is even deleted, the record of corresponding virtual machine and USB device in mapping table
It not will be deleted, it is deleted simply by modification deleted marker position surface virtual machine, at this moment, it can reflected according to described
Firing table obtains the information for the corresponding USB device of the virtual machine deleted, and discharges corresponding USB device.
Method disclosed by the invention passes through the information and corresponding virtual machine letter for the USB device that will be mounted on virtual machine
Breath is recorded in database, when carrying out virtual machine and restarting, corresponding information can be inquired, to obtain virtual machine carry
USB device, and then the USB device that front mount is restarted in virtual machine continuation is mounted on virtual machine again.And it can also delete
Corresponding USB device is discharged when except virtual machine.
Based on the same inventive concept, according to another aspect of the present invention, as shown in figure 3, the embodiment of the present invention also mentions
Supply a kind of computer equipment 501, comprising:
At least one processor 520；And
Memory 510, memory 510 are stored with the computer program 511 that can be run on a processor, and processor 520 is held
The step of method of any Virtual Machine Manager USB device as above is executed when line program.
Based on the same inventive concept, according to another aspect of the present invention, as shown in figure 4, the embodiment of the present invention also mentions
A kind of computer readable storage medium 601 is supplied, computer readable storage medium 601 is stored with computer program instructions 610, meter
The step of method of any Virtual Machine Manager USB device as above is executed when calculation machine program instruction 610 is executed by processor.
