I have recently decided to use proxmox ve 6 as my hypervisor for my desktop. I imported vm images and replicated the same setup as I've had in a test install of proxmox ve 5. My linux VM works normally with GPU passthrough (gtx 1060, extracted vBIOS, added x-vga=1). However when starting my windows VM the display cuts off after the nvidia drivers install. I tried setting hidden=1 in cpu, hv-vendor-id and also directly adding arguments with the "args:" option in the configuration. I then tried to reinstall windows and the same thing happens after installing nvidia drivers. I am using windows 1903 and proxmox ve 6.
ALSO NOTE:
I tried running the following command and the "hv_vendor_id" option seems to be missiong from "- cpu":
qm showcmd 200:
SOLUTION!!!!:
there seems to be a new problem introduced in qemu 4.0 and therefore proxmox ve 6!
Add this to config:
