It include: detection local disk information；The local disk information is sent to server by shared disk channel.
Before step S2 further include: refresh the display simulation USB disk.
Server described in step S2 receives the read-write requests to the simulation USB disk, specifically includes: Yong Hufang
When asking the file on the simulation USB disk, server obtains disk read-write by virtual equipment driver and requests.
After operating result is returned to server in step S2, further includes: be transmitted to the operating result virtually
Machine, user's operation are completed.
When step S3 medium cloud terminal and server disconnect, is sent by cloud terminal to server and disconnect local disk life
It enables.
A kind of cloud terminal of the invention redirects local disk to the system of virtual machine, comprising: the cloud terminal that is sequentially connected,
Server and virtual machine；It further include the simulation USB disk patched with virtual machine；When cloud terminal and server establish connection, send
Local disk information goes out and the local disk same size to server, server according to the local disk information simulation
USB disk, and the USB disk of the simulation is inserted into virtual machine；When server is received to the simulation USB disk
When read-write requests, the read-write requests are transmitted to cloud terminal, cloud terminal operates corresponding disk according to the read-write requests,
And operating result is returned into server；When cloud terminal and server disconnect, server by the USB disk of the simulation from
It is extracted in virtual machine.
Cloud terminal of the invention redirects local disk to the method and system of virtual machine, redirects this on hardware view
Local disk avoids the disk operating that the prior art does not support more bottom into virtual machine, shared to bring safe topic.

[specific embodiment]
The present invention relates to a kind of method and system of cloud terminal redirection local disk to virtual machine.It is above-mentioned existing in order to solve
There is the problem of technology, inventor is in view of that can transmit the information of local disk when cloud terminal and server establish connection
To server, server simulates a USB mobile disk and is inserted into virtual machine, Jin Ershi according to terminal disc information
Existing cloud terminal redirects local disk to virtual machine.Specific embodiment is as follows.
The method of embodiment 1, the cloud terminal of the present embodiment redirection local disk to virtual machine, it is shown in Figure 1, including
Following key step:
When S11, cloud terminal and server establish connection, local disk information is sent to server, server is according to
Local disk information simulation go out USB disk with the local disk same size, and the USB disk of the simulation is inserted into
In virtual machine.
S12, when server receive to it is described simulation USB disk read-write requests when, the read-write requests are transmitted to
Cloud terminal, cloud terminal operates corresponding disk according to the read-write requests, and operating result is returned to server.
When S13, cloud terminal and server disconnect, server extracts the USB disk of the simulation from virtual machine.
The detailed process of above-mentioned steps S11 is referring to shown in Fig. 1-1, including following details step:
