We should detect KVM virtual video adapter there: https://github.com/inga-lovinde/RadeonResetBugFix/blob/master/RadeonResetBugFixService/Devices/KnownDevices.cs

However, I don't know what is it Manufacturer/Service/ClassName combination. KVM users can open a pull request, or comment with these so I will know what to add:

The Red Hat QXL VGA adapter (commonly seen in -vga qxl with QEMU) has these values:

Manufacturer: Red Hat, Inc.

Service: QxlDod

Class: Display

oops this might fit better under QEMU Support but i'm pretty sure they both use this adapter anyway

can at least confirm this does not break anything and seems to work as expected with the following setup:

• kvm/qemu/libvirt
• windows 10 guest
• radeon hd 7970 passed through
• qxl as virtualized gpu
• looking-glass service set up to automatically restart on fail, as it will fail on startup with this fix

I am not sure if this my card actually does suffer from a reset bug, but i thought i'd try this because once in a while my vm will start but have no display output and won't react to acpi shutdown commands.
