Yeah, I'm not happy with that either - was also going to say (seems my
patch notes got lost somewhere) that using PVE::RS::VFIO means
get_mdev_types() doesn't only deal with sysfs stuff anymore - so might
make sense to move the mdev stuff anyway.

Right, I knew I forgot something - sorry.

A separate package for vfio/mdev/vgpu type stuff could make sense, as
that code will probably grow some more.
OTOH, if (most) new stuff is implemented through
proxmox-ve-rs/proxmox-perl-rs in the future, having it live in
qemu-server definitely makes a lot of sense too, I think.

I'm open to suggestions in any case, happy to rework that as needed.
