RE: AMD Radeon GPU Passthrough
I've never gotten errors like that, it just doesn't work when it is pass through.
Another thing I found a little odd was that the graphics card shows up as a usb device in Windows -

RE: AMD Radeon GPU Passthrough
@jmccoy555
It's definite not the same for consumer grade cards unfortunately
At least not any recent card. I have an old ATI HD5xxx card that XCP-ng recognizes and am able to assign to a VM via the VM's advance settings in XO.Do you need to install the drivers for that card in the VM, or does it just work?
The problem for me arises when I try to install the drivers, but before I try to install them the VM becomes very unstable, which tells me there's something going wrong when I pass the pci lanes

RE: AMD Radeon GPU Passthrough
I have been trying to pass through a graphics card as well.
Previously, on XCP-ng 8.1, I had no issues doing this, except for the reset issue that is caused by the graphics card. On XCP-ng 8.2, passing through the graphics card has become really difficult. The VM that is assigned the pci lanes, in my situation a Windows vm, becomes really unstable. The vm sees the graphics card, but if I attempt to install the Radeon drivers, the vm crashes and I'm no longer able to start it.
@Johnkrips These issues might be due to the pci issues related to the 8.2

RE: machine type
@technot
This is interesting. I'm able to download the latest amd drivers and install them, only issue being what I've mentioned before about getting error 43 until I reboot the server. -
RE: PCI Passthrough back to dom0
Thanks for all the help everyone. Everyone here is always very helpful
How does one go about modifying the docs? -
RE: PCI Passthrough back to dom0
@dthenot Before this thread dies, I just wanted to ask one more thing.
How would you go about only giving back one pci device back dom0? -
RE: PCI Passthrough back to dom0
I see. I suspected that line in the docs would be it.
In that case, may I suggest modifying the wording in the docs? The current wording suggests the opposite. At least it does to me. The "from" in the docs makes it read as if you are hiding all devices from dom0.
