AMD GPU Share between VMs

[Gordack]

Hi,
I was thinking to setup proxmox for my homelab.
I have a quick question. I have a signle rx 580 8gb installed on my rig. Can I share this GPU between linux and windows at the same time using proxmox ?

No, you can only PCI passthrough the VM to a single VM and then it can't be used on the host anymore. If you don't got a Geforce 9XX/10XX/20XX/30XX with hacked firmware/drivers and windows or a Radeon Pro GPU with SR-IOV support there is no way to use a GPU on multiple VMs.
