Do you have any hints on how to set up a similar system? Links, guides, gotchas, whatnot? I've seen someone mention this setup before (perhaps it was you?) and I'm sure I'm not the only one interested in running something similar.
Also I recently discovered some very in-depth blog posts here: https://heiko-sieger.info/iommu-groups-what-you-need-to-cons...
Another whole website about this topic (no joke): https://passthroughpo.st/
The most complete guide is probably the Arch Linux one: https://wiki.archlinux.org/index.php/PCI_passthrough_via_OVM....
