hello,
after install a new Proxmox PVE i get this message i n the system log :

I saw a solution in another forum post:

open the file `/etc/pve/qemu-server/VMID.conf`. You need to make changes to the "args" row about this: Code: args: -set device.hostpci0.x-igd-gms=0x4

but I haven't created any VMs at all yet
does anyone else have a solution?
