Hey guys,
Having a rough time trying to get a simple GPU passthrough working with a windows 10 (now 11) VM. The OS does recognize the GPU, but lthe resolution is painfully low, and when I look at the adapter properties in device manager, it says "a driver for this device has been disabled," so it's not liking the driver. I've tried a few different things for the driver:
1) Using SpaceInvader One's script to dump the ROM from the card. I haven't been able to get this to work. I get a message that the ROM is too small (under 70kb) and that it will try to reconnect the card. It has me push the power button on my system, and then does nothing when the system comes back from whatever hibernate state it went into.
2) Found what sounds like a matching ROM from techpowerup. This is a Geforce GT 710 1GB. I set the VM to use this as the ROM BIOS.
3) Within the VM, tried manually updating drivers, pointing to the QXL and QXLDOD folders from the VIRTIO drive. I just always get the message that the best drivers are already installed.
4) Within the VM, installed the drivers directly from Nvidia. This results in no change.
The graphics and sound are in their own IOMMU group together.
I'm using the latest VIRTIO driver.
Is there anything I haven't thought of? Appreciate any help.
