HyperV has GPU para virtualization
But for qemu,kvm,xen it seems like the best option is to passthrough a GPU to a single VM, unless the GPU supports srvio, which almost all of the retail cards don’t.
I head about the woof and gaming on whales project, and they seem to get around this by using only containers for the subdivision.
What methods or options have you used to share a GPU with your VMs?
Currently I simply dont.
On Xenn you should be capable with the correct drivers to put a couple of virtual GPU Profiles on your VMs to use.
On Hyper-V there is a command out there, but I don’t know if its a dedicated access or if you are capable of sharing it across multiple instances.
On Proxmox though? Not sure but i think it was possible to forward it to a VM but thats all. Just dedicated acces afaik.
