GPU assignment

The state of GPU assignment in QEMU/KVM:



ARMv8/arm-64: use virtio-gpu because the legacy VGA framebuffer is very troublesome on aarch64

NVIDIA Certified
GRID vGPU is a licensed feature on Tesla M6, Tesla M10, and Tesla M60.


AMD MxGPU is the world’s first hardware-based virtualized GPU solution, is built on industry standard SR-IOV (Single-Root I/O Virtualization) technology. Supprot VMWARE & Citrix.

Intel® Graphics Virtualization Technology

  • –d (Intel® GVT –d): vDGA: virtual dedicated graphics acceleration (one VM to one physical GPU)
  • –s (Intel® GVT -s): vSGA: virtual shared graphics acceleration (multiple VMs to one physical GPU)
  • –g (Intel® GVT -g): vGPU: virtual graphics processing unit (multiple VMs to one physical GPU)

Visit Intel GVT-g page for more.

Optional Firmware

GuC:designed to perform graphics workload scheduling on the various graphics parallel engines.
DMC: low-power idle states. It provides capability to save and restore display registers across these low-power states independently from the OS/Kernel.
HUC: offload some of the media functions from the CPU to GPU.
