Selfhosted

A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Rules:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

I can’t even figure out how to tell if it’s supported or not. If it is supported, I can’t figure out how to enable it. If it is enabled, idk where I should be seeing it in proxmox!

Can anyone point me in the right direction?

Where does it say that? On some boards you need to adjust iommu but other than that it shouldn't be a problem if the CPU supports it. I am not an expert and if I am wrong I would like you to prove it.

The previous site already shows this in practice, but here's a more technical explanation for you

Here's some more real life examples: https://forum.level1techs.com/t/vfio-passthrough-in-2023-call-to-arms/199671/18

Passed that you can take your skepticism somewhere else, I don't really care that you don't believe me, it doesn't change the reality of how IOMMU groups work.

Grouping has become overall better since X570, but still not a given.
