Gpu passthrough and host same time

[mer0x39]

Hello, I want to know if it s possible to passthrough dedicated GPU to the VM and to be used by Proxmox host in the same time? If yes, how should be this done? Thank you!

i know that a gpu can be shared between to up to 7 VMs (highly depends on some creteria)
but why somebody want to use gpu on proxmox ? for compatibility reasons use the onboad graphikcard.

Hi,
that is currently not really possible. What you might want to look at is VirGL, but that only works with Linux guests.

If you are refering to Nvidias MIG, that's going to be very expensive and probably not what the OP is looking for. There is some interesting stuff happening around the Intel Flex cards, but that's still unfolding and would still be pretty expensive
