Only 3 resolution when VirtIO-GPU or VirtGL-GPU enabled in Windows Guest

[dfc643]

Hi everyone,

I find there only 3 resolution when VirtIO-GPU or VirtGL-GPU enabled in Windows guest.
1920x1080,
1280x1024,
1024x768

how to add more modes in Windows guest when uses virtio-gpu or virgl as video backend?
just like:
1280x720
1280x800
1366x768
1440x900

thanks.

only 3 resolution mdoes:

virtio driver was installed and it works fine:


and the virgl driver missing opengl 2.0+ or vulkan supports.

neither virtio-gpu nor the virgl gpu have proper windows driver, both are currently linux only, so i guess that's the reason why windows falls back to only some resolutions (and no proper opengl support)
also vulkan is not supported for either of those gpus (not even on linux)

Are there plans to provide vulkan support for linux VMs using AMD Radeon cards (perhaps as an alternative to PCI passthrough)?

I set my gpu to 'virtio' but my windows only show 'Microsoft compatible Video Adaptor' and the driver 'virgpudo' can not be installed.

So how can you do that?

Hope you can help me to get one VirtIO-GPU.

is still valid
