even tried vnc

So, it doesn't work with qxl/vnc graphics?

Is the vm booting to bios?Where it hangs?

 

For gpu passthrough, since you have the nvidia driver plugin, try to isolate (attach to vfio) at boot the gpu, iommu groups 90 and 91, reboot and try. Attach new diagnostics if it wont work.

But first you need to make it work with qxl+vnc.

 

About "Windows 10vnc" vm, what's the output of:

fdisk -l "/mnt/user/domains/Windows 10vnc/vdisk1.img"

Thank you for your reply. not sure why but vnc is now working. ive isolated 90 and 91  and restarted but still cant get vms working on gpu. windows 10vnc was just one id tried to see if i try different settings to see if i could get it to work. i just want to have at end 1x windows and 1x linux setup and ill delete the others

this is my diagnostics

 

many thanks lance
