[vfio-users] vfio, xeon e3s, acs, & gpus -- oh my!

[Joshua Lee]

What do you mean by "iffy"? My $200 x99 board has seperate IOMMU groups
per-device, and a i7 5820k/6800k or, if you want it cheaper, an E5-1620v3
or 1620v4, can do ACS and sane IOMMU groups with it for under $600 also,
without needing to get a used processor...
