The host machine also has a quite nice Nvidia GPU.
I have not been able to work out how to access it from the VMs. The
instructions I have found are way too scary for me to attempt.

[If anyone has a straightforward way of doing it I would love to hear
about it.]

For the few things that need it [Blender and MeshLab] I just use the
host machine.
