Abstract

Examples described herein relate to a manageability controller for controlling a display of a screen video. The manageability controller may receive screen video data from a hypervisor running on a host operating system (OS) that is executable by a main processing resource separate from the manageability processing resource. The screen video data may include a host OS screen video data corresponding to the host OS, a virtual machine (VM) screen video data corresponding to a VM running on the hypervisor, or both. Further, the manageability controller may store the host OS screen video data or the VM screen video data in a physical video memory based on a screen selection input.

First claim

We claim:

1. A manageability controller comprising:
a non-transitory machine-readable medium storing instructions; and
a manageability processing resource coupled to the non-transitory machine-readable medium, the instructions executable on the manageability processing resource to:
receive, at the manageability controller, screen video data from a hypervisor running on a host operating system (OS) that is executable by a main processing resource separate from the manageability processing resource, wherein the screen video data comprises host OS screen video data of the host OS, and virtual machine (VM) screen video data of a VM running on the hypervisor, wherein the host OS screen video data is provided by the host OS, and the host OS screen video data received at the manageability controller is obtained b y a video driver of the hypervisor from a first virtual storage region created by the host OS, and wherein the hypervisor comprises a video management agent to access the host OS screen video data from the first virtual storage region and the VM screen video data from a second virtual storage region;
receive, by the manageability controller, a screen selection input from a user via a local input device or a web-console accessible from a remote computing system; and
store the host OS screen video data and the VM screen video data in a physical video memory based on the screen selection input.

2. The manageability controller of claim 1 , wherein the storing of the host OS screen video data of the host OS in the first virtual storage region virtualizes the host OS screen video data.

3. The manageability controller of claim 1 , wherein the first virtual storage region and the second virtual storage region are allocated separate storage space of a kernel memory associated with the host OS.

4. The manageability controller of claim 1 , wherein the host OS screen video data and the VM screen video data received at the manageability processing resource from the hypervisor is encoded by the video management agent in accordance with a video encoding protocol.

5. The manageability controller of claim 1 , wherein the instructions are executable on the manageability processing resource to:
determine that the screen selection input comprises a selection of the host OS screen video data; and
select, in response to determining that the screen selection input comprises the selection of the host OS screen video data, the host OS screen video data to store in the physical video memory.

6. The manageability controller of claim 1 , wherein the instructions are executable on the manageability processing resource to:
determine that the screen selection input comprises a selection of the VM screen video data; and
select, in response to determining that the screen selection input comprises the selection of the VM screen video data, the VM screen video data to store in the physical video memory.

7. The manageability controller of claim 1 , wherein the instructions are executable on the manageability processing resource to display the host OS screen video data or the VM screen video data on the web-console based on the screen selection input.

8. The manageability controller of claim 1 , wherein the physical video memory is accessible by a graphics processor to display, on a display device, a video corresponding to the host OS screen video data stored in the physical video memory by the manageability processing resource, and wherein the manageability controller is to store the host OS screen video data in the physical video memory instead of the host OS.

9. A method comprising:
receiving, by a manageability controller separate from a main processing resource of a computing system, screen video data from a hypervisor running on a host OS that is executable by the main processing resource, wherein the screen video data comprises host OS screen video data corresponding to the host OS and VM screen video data corresponding to a VM running on the hypervisor, wherein the host OS screen video data is provided by the host OS, and the host OS screen video data received at the manageability controller is obtained by a video driver of the hypervisor from a first virtual storage region created by the host OS, and wherein the hypervisor comprises a video management agent to access the host OS screen video data from the first virtual storage region and the VM screen video data from a second virtual storage region;
receiving, by the manageability controller, a screen selection input from a user via a local input device or a web-console accessible from a remote computing system; and
selectively storing, by the manageability controller, the host OS screen video data or the VM screen video data in a physical video memory based on the screen selection input.

10. The method of claim 9 , further comprising:
determining that the screen selection input comprises a selection of the host OS screen video data; and
selecting, in response to determining that the screen selection input comprises the selection of the host OS screen video data, the host OS screen video data to store in the physical video memory.

11. The method of claim 9 , further comprising:
determining that the screen selection input comprises a selection of the VM screen video data; and
selecting, in response to determining that the screen selection input comprises the selection of the VM screen video data, the VM screen video data to store in the physical video memory.

12. The method of claim 9 , wherein the manageability controller stores the host OS screen video data in the physical video memory instead of the host OS.

13. A non-transitory machine-readable medium storing instructions executable by a manageability controller separate from a main processing resource executing a host operating system (OS) to:
receive, at the manageability controller, screen video data from a hypervisor running on the host OS, wherein the screen video data comprises host OS screen video data corresponding to the host OS and VM screen video data corresponding to a VM running on the hypervisor, wherein the host OS screen video data is provided by the host OS, and the host OS screen video data received at the manageability controller is obtained by a video driver of the hypervisor from a first virtual storage region created by the host OS, and wherein the hypervisor comprises a video management agent to access the host OS screen video data from the first virtual storage region and the VM screen video data from a second virtual storage region;
receive, at the manageability controller, a screen selection input from a user via a local input device or a web-console accessible from a remote computing system; and
store the host OS screen video data or the VM screen video data in a physical video memory based on the screen selection input.

14. The non-transitory machine-readable medium of claim 13 , further comprising instructions executable by the manageability controller to select, in response to determining that the screen selection input comprises the selection of the host OS screen video data, the host OS screen video data to store in the physical video memory.

15. The non-transitory machine-readable medium of claim 13 , further comprising instructions executable by the manageability controller to select, in response to determining that the screen selection input comprises the selection of the VM screen video data, the VM screen video data to store in the physical video memory.

16. The non-transitory machine-readable medium of claim 13 , wherein the manageability controller stores the host OS
