My server has been crashing on a daily basis for the past couple of weeks. I restart it manually after the crash, which triggers a parity check. The log looks to me like a kernel panic, which immediately made me think it could be hardware related since I swapped my motherboard recently. However, the motherboard swap happened about 10 days before it started crashing daily. In that time, I remember trying to set up a docker compose for some new containers which continually locked up my server when I tried to run them. I moved the stack into portainer to be managed there and it seems to be fine from there. I have run a memtest86 and it passed after running overnight. I've attached the logs from right before the crash last night! syslog-192.168.1.2.log.1

Interesting, I was able to install virt manager Docker container and it immediately worked with the default Docker settings.

That is perfect and I literally just found that on my own before seeing your message. I think this proves that what I want to do is possible from within a Docker container, and it doesn't even need to be privileged. I think I have all the pieces I need, I just need to put them together now. Thanks for the help.

Interesting! Yes, the libvert library for Python looks like an excellent way of achieving this. Do you know if it's possible to access host VMs from inside a privileged Docker container? I'd like to package this as a container since it runs a web server. But yes, all I really need is the basic functions; start, stop, kill, and list. Not looking for a full control of available domains or anything like that via API.

There have been other attempts at making an API for the Unraid VM manager, allowing for starting/stopping of VMs from another interface, like Home Assistant. However, from what I've seen those attempts relied on scraping of the Unraid Web UI using a headless browser. I am wondering if anyone has tried creating a wrapper around the `virsh` CLI tool available on Unraid's shell to create an API to control VM functions. It seems like this would be possible to implement as an Unraid Plugin, or potentially even in a Docker container using chroot to allow command execution on the host. This, I imagine, would be much faster and lower overhead than using the Unraid UI scraping method to control VMs. I am interesting in working on this, but I don't have any experience making Unraid Plugins or apps.

Not too worried about the audio issue- I use audio via a Dell USB docking station anyway. Hopefully I'm able to get that thing working. Do you have a GPU passed through as well? Sounds like you have the same setup I'm aiming for.

What's the latest on IOMMU groups? I have a good deal on a i5 12600k + ASUS Z690 Motherboard combo. I'm hoping to run a Windows VM for gaming with a GPU, will it be possible? Have people had any luck with this kind of setup on one of these CPUs?
