A single virtual GPU can be assigned only to a single virtual machine - create as many GUIDs as you want virtual GPUs.

Generate a virtual GPU GUID ( $GVT_GUID in commands below) which you will use to create and assign the virtual GPU.It looks like this: 0000:00:02.0 - you can look it up by running lspci -D -nn, looking for VGA compatible controller: Intel Corporation HD Graphics. Find the PCI address and domain number of your GPU ( $GVT_PCI and $GVT_DOM in commands below), as it resides in /sys/bus/pci/devices.Add i915.enable_guc=0 to kernel parameters, see warning at Intel graphics#Enable GuC / HuC firmware loading.Set i915 module parameter enable_gvt=1 to enable GPU virtualization.Enable kernel modules: kvmgt, vfio-iommu-type1 and mdev.Enable IOMMU by adding intel_iommu=on to your kernel parameters.(The virtual GPU actually does need specialized drivers to work correctly, but all the required changes are present in the latest upstream Linux/Windows drivers.)

The guest with a virtual GPU sees it as a "regular" GPU - just install the latest native drivers. You will have to create a virtual GPU first, then assign it to your virtual machine.
