I managed to set up win10 guest under PVE6.2 and wanted to host some emulator which requires nest virtualization.
After searching from forum, I need to add args: -cpu host,+svm in the conf file.
Then I reboot the GTX1080 stopped working. It still display video on screen but with like 640x480 resolution and the driver does not load (Error Code 43)
And I remove the line "args: -cpu host,+svm" fixed the issue and the video driver loaded and output with 4K resolution.
Is it a known issue that +svm cannot coexist with GPU passthrough?
(I have only 1 GPU in system, so the host is running headless)
Thank you.
