Notes on device passthrough configuration for KVM hosts
2024 ADDENDUM TO BELOW NOTES:
1. I have found that the linux-amd-znver3 kernel reliaby works for passthrough, initializing devices in a sane order and respecting boot-time blacklist kernel args https://aur.archlinux.org/packages/linux-amd-znver3
2. I have since managed to get the Nvidia RTX A2000 12GB working in passthrough with a few different settings which I will document here Real Soon Now, I Swear™.
3. The RTX 4000 SFF Ada Generation 20GB works as a drop-in replacement for the A2000.
4. Stability is not guaranteed - I don't know what to blame, but it's infrequent enough (i.e. one crash every few months) that I haven't spent time on it.
5. I have recently transitioned away from Arch to openSUSE Tumbleweed, which works out-of-the-box as a passthrough host and does not constantly break.
6. I am separately maintaning a variant of the linux-amd-znver3 and linux-amd-znver2 configs which have been tweaked to work on openSUSE. I can share these or even provide builds if there is interest.
2022 NOTES - FULLY WOR

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

  1. Clarify and agree on the scope of the system
  • User cases (description of sequences of events that, taken together, lead to a system doing something useful)
    • Who is going to use it?
    • How are they going to use it?
