+Notes
+* There are two sizes of vGPU you can create:
+** <code>i915-GVTg_V5_4</code> supports up to 1920x1200
+** <code>i915-GVTg_V5_8</code> supports up to 1024x768
+** See <code>cat /sys/devices/pci0000:00/0000:00:02.0/mdev_supported_types/i915-GVTg_V5_8/description</code> to get a description of the vgpu.
+** On my nodes, I can create a single <code>i915-GVTg_V5_4</code> or two <code>i915-GVTg_V5_8</code>
+* See [[Archwiki:Intel GVT-g]] for details
