So with Fedora 42, you can create VMs that use Venus to expose a GPU to VMs that passes through Vulkan commands to the host graphics card. Meaning I can create VMs to run an application that requires a GPU (using Intel 12th graphics!). You have to use raw QEMU because libvirt does not support the necessary options yet.

Obviously not the best for performance (but I don't care), but you don't have to source datacenter GPUs or strange patches- standard Intel integrated graphics + Fedora packages.
