Abstract

A method and system for the display device configuration in a VM environment are disclosed. In one embodiment, the method includes determining one or more devices in a display system of a client and transmitting client display system information to a host running one or more VMs. Further, a notification is received by the client from the host indicating that display settings of the VM were configured based on the client display system information.

Claims

1. A computer-implemented method, comprising:

identifying, by a client device, one or more physical display devices coupled with the client device;

transmitting, by the client device, client display information to a host running one or more virtual machines (VMs), the client display information comprising current settings of each of the one or more physical display devices, wherein each VM has one or more virtual devices, each of the one or more virtual devices being associated with one of the one or more physical display devices;

receiving, by the client device, current settings of a virtual device of the one or more virtual devices; and

when the current settings of the virtual device differ from current settings of an associated physical display device, adjusting the current settings of the associated physical display device according to the current settings of the virtual device.

2. The method of claim 1, wherein the client display information comprises an identifier of each of the one or more physical display devices.

3. The method of claim 1, wherein the client display information further identifies one or more alternative settings supported by each physical display device of the client.

4. The method of claim 1, further comprising receiving a notification from the host that display settings of the corresponding VM has changed, the notification comprising the current settings of the virtual device of the corresponding VM, wherein the current settings of the associated physical display device are adjusted prior to a communication between the corresponding VM and the associated physical display device.

5. The method of claim 1, further comprising receiving a mode operation message from the host, the mode operation message comprising the current settings of the virtual device of the corresponding VM, wherein the current settings of the associated physical display device are adjusted after a communication between the corresponding VM and the associated physical display device.

6. The method of claim 1, wherein the current settings of the virtual device and the associated physical display device comprise at least one of resolution, orientation, display position, color depth, or sub-pixel order.

7. The method of claim 1, further comprising:

detecting a change in the current settings of the associated physical display device during an active display connection between the corresponding VM and the associated physical display device;

sending changed settings of the associated physical display device to the corresponding VM; and

receiving a notification from the corresponding VM indicating that the display information of the corresponding VM was configured based on the changed settings of the associated physical display device devices.

8. A system, comprising:

a processing device;

a memory; and

one or more physical display devices coupled to the processing device and memory, wherein the processing device is to;

transmit client display information to a host running one or more virtual machines (VMs), the client display information comprising current settings of each of the one or more physical display devices, wherein each VM has one or more virtual devices, each of the one or more virtual devices being associated with one of the one or more physical display devices;

receive current settings of a virtual device of the one or more virtual devices; and

when the current settings of the virtual device differ from current settings of an associated physical display device, adjust the current settings of the associated physical display device according to the current settings of the virtual device.

9. The system of claim 8, wherein the client display information comprises an identifier of each of the one or more physical display devices.

10. The system of claim 8, wherein the client display information further identifies one or more alternative settings supported by each physical display device of the client.

11. The system of claim 8, wherein the processing device is further to receive a notification from the host that display settings of the corresponding VM has changed, the notification comprising the current settings of the virtual device of the corresponding VM, wherein the current settings of the associated physical display device are adjusted prior to a communication between the corresponding VM and the associated physical display device.

12. The system of claim 8, wherein the processing device is further to receive a mode operation message from the host, the mode operation message comprising the current settings of the virtual device of the corresponding VM, wherein the current settings of the associated physical display device are adjusted after a communication between the corresponding VM and the associated physical display device.

13. The system of claim 8, wherein the current settings of the virtual device and the associated physical display device comprise at least one of resolution, orientation, display position, color depth, or sub-pixel order.

14. The system of claim 8, wherein the processing device is further to:

detect a change in the current settings of the associated physical display device during an active display connection between the corresponding VM and the associated physical display device;

send changed settings of the associated physical display device to the corresponding VM; and

receive a notification from the corresponding VM indicating that the display information of the corresponding VM was configured based on the changed settings of the associated physical display device.

15. A computer-readable storage medium having computer instructions stored therein, which when executed by a client device, cause the client device to perform a method comprising:

identifying, by the client device, one or more physical display devices coupled with the client device;

transmitting, by the client device, client display information to a host running one or more virtual machines (VMs), the client display information comprising current settings of each of the one or more physical display devices, wherein each VM has one or more virtual devices, each of the one or more virtual devices being associated with one of the one or more physical display devices;

receiving, by the client device, current settings of a virtual device of the one or more virtual devices; and

when the current settings of the virtual device differ from current settings of an associated physical display device, adjusting the current settings of the associated physical display device according to the current settings of the virtual device.

16. The computer-readable storage medium of claim 15, wherein the client display information comprises an identifier of each of the one or more physical display devices.

17. The computer-readable storage medium of claim 15, wherein the client display information further identifies one or more alternative settings supported by each physical display device of the client.

18. The computer-readable storage medium of claim 15, wherein the method further comprises receiving a notification from the host that display settings of the corresponding VM has changed, the notification comprising the current settings of the virtual device of the corresponding VM, wherein the current settings of the associated physical display device are adjusted prior to a communication between the corresponding VM and the associated physical display device.

19. The computer-readable storage medium of claim 15, wherein the method further comprises receiving a mode operation message from the host, the mode operation message comprising the current settings of the virtual device of the corresponding VM, wherein the current settings of the associated physical display device are adjusted after a communication between the corresponding VM and the associated physical display device.

20. The computer-readable storage medium of claim 15, wherein the current settings of the virtual device and the associated physical display device comprise at least one of resolution, orientation, display position, color depth, or sub-pixel order.
