Description
Technical field
The present invention relates to fictitious host computer technology, be specifically related to I/O redirection system and its implementation of fictitious host computer based on cloud computing infrastructure environment.
Background technology
Along with the continuous development of cloud computing technology and generally popularization, make that the PC physical host of original operation Windows and Linux is constantly virtual, realize that the user can be by network and different terminal equipment use fictitious host computer.
Use the general fashion of fictitious host computer to have two kinds:
One, as shown in Figure 1; Fictitious host computer software (like VMWare, VirtualBox, XenServer etc.) is installed on physical host, is gone out a plurality of fictitious host computer instances with the fictitious host computer software creation, like fictitious host computer instance VM1;, fictitious host computer instance VMn (n is the natural number greater than 0).Each fictitious host computer instance can be according to the demand installing operating system, like WINDOWS or LINUX.Each fictitious host computer instance is with regard to as same physical host, but its input-output equipment driving all is virtualized (because the fictitious host computer technology is very ripe, just not giving unnecessary details).The user can operate through local ancillary equipment, on the fictitious host computer administration interface on the physical host, logins use, uses but generally be only limited to the IT administrative staff.
Two, as shown in Figure 2; The user is through PC or thin client (ThinClient) the remote desktop program communication inner with the fictitious host computer instance; Like remote desktop programs such as RDP, ICA, PCoverPC, VNC, use the fictitious host computer instance with one of them multi-user's identity of fictitious host computer instance.PC or thin client can be referred to as remote terminal.
Remote terminal is when remote operation; Because the operating system version of different virtual main frame instance is different; The disposal ability of remote dummy desktop programs is different with supporting technology; And need to rely on third party's remote dummy desktop programs and remove to operate the fictitious host computer instance, caused the user can not be as using local physical host to use the function of fictitious host computer instance glibly, fully.
Summary of the invention
In order to overcome the deficiency of prior art; The objective of the invention is to propose I/O redirection system and its implementation of a kind of fictitious host computer; It is the system that on the basis of fictitious host computer software, increases; It can change existing fictitious host computer instance can only rely on the control mode of the remote dummy desktop programs in the fictitious host computer instance for remote terminal, thereby remote terminal is used and experiencing virtual main frame instance fully, safely and neatly.
In order to achieve the above object, the technical scheme that the present invention adopted is following:
A kind of I/O redirection system of fictitious host computer, it comprises communication module, is redirected link block; Redirected link block comprises the redirected proxy module that connects; Remote terminal connects proxy module transmission connection request through communication module to being redirected; After redirected connection proxy module receives connection request, obtain fictitious host computer instance information list to fictitious host computer software, and feed back to remote terminal to fictitious host computer instance information list through communication module; Remote terminal is selected a fictitious host computer instance from fictitious host computer instance information list, and connects proxy module to this fictitious host computer instance proposition control request through communication module to being redirected; After redirected connection proxy module receives control request; Running status to this fictitious host computer instance of fictitious host computer software query; If this fictitious host computer instance is in off-mode, then this fictitious host computer instance of fictitious host computer software startup is in open state as if this fictitious host computer instance; Then be redirected the connection proxy module and obtain the drive arrangements of the virtual I/O device of this fictitious host computer instance, and create a redirection module from fictitious host computer software; Redirection module comprises data coding module, is redirected input module, is redirected output module and each virtual unit driving instance; It is corresponding with the driving of the virtual I/O device of this fictitious host computer instance that each virtual unit drives instance, and data coding module is used to separate or make up the inputoutput data that virtual unit drives instance; The output information of virtual I/O device drives instance through corresponding virtual unit and is transferred to redirected output module; Redirected output module is transferred to data coding module to output information again, and data coding module is transferred to the remote terminal that proposes control request through communication module after output information is encoded; The input information of remote terminal is transferred to data coding module through communication module; Data coding module sends to redirected input module after input information is decoded, and redirected input module drives instance to decoded input information through corresponding virtual unit again and is transferred to this fictitious host computer instance.
Preferably; Said redirection module comprises that also one is redirected control module; When the input information that receives when data coding module was fictitious host computer example state control command, data coding module was sent fictitious host computer example state control command through being redirected control module to fictitious host computer software; Fictitious host computer example state control command comprises change resolution instruction or shutdown command or restart instruction or log-out instruction.Preferred, after fictitious host computer software receives shutdown command, be redirected the connection proxy module and close and the corresponding redirection module of this fictitious host computer instance.
Preferably, said redirected link block also comprises the Certificate Authority module; After redirected connection proxy module receives connection request; Obtain fictitious host computer instance information list to fictitious host computer software; And feed back to fictitious host computer instance information list in the process of remote terminal through communication module: after redirected connection proxy module receives connection request, require remote terminal input authentication information, after the remote terminal input user profile; Redirect agent is sent user profile to the Certificate Authority module; User profile is redirected the connection proxy module and obtains fictitious host computer instance information list from fictitious host computer software, and feed back to remote terminal to fictitious host computer instance information list through communication module through after the authentication of Certificate Authority module.
