Hi,

New to Proxmox and having issues with vGPU passthrough.

Followed instructions as per the youtube video - https://www.youtube.com/watch?v=jTXPMcBqoi8

My system is a HP Z640 - Xeon E5-1650 v3 3.50Ghz 32GB RAM, 2 x 240GB SSD (Proxmox installed on SSD with a ZFS - RAID1), Quadro M6000 12GB, and VM's running on a 2 x 500GB NVMe. Also on a ZFS RAID - 1.

I want to passthrough my 'Quadro M6000 - 12GB' to multiple VM (3 if possible. only trying to get 1 to work with 4GB for now).

Getting the following error when trying to launch a Windows 10 VM with the PCI device attached (Otherwise Windows VM boots up fine) :

kvm: -device vfio-pci,sysfsdev=/sys/bus/mdev/devices/00000000-0000-0000-0000-000000000110,id=hostpci0,bus=ich9-pcie-port-1,addr=0x0,bootindex=103: vfio 00000000-0000-0000-0000-000000000110: error getting device from group 41: Input/output error
Verify all devices in group 41 are bound to vfio-<bus> or pci-stub and not already in use
TASK ERROR: start failed: QEMU exited with code 1

Been trying to figure this out by going through other post for several days, but have been unsuccessful.

I have also attached the SYSLOG file and a few other files that might help someone who can make heads or tails of it.

Any help will be greatly appreciated and thanks in advance.
