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.

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?

Stable Diffusion GUIs list

This will help me and hopefully other to get everything going and generate waifus images with Stable Diffusion, and maybe other txt2img things maybe.

I will probably add shields.io to make it more easier to read (maybe)

Tip

Check out the SD Anime Checkpoints list.
