Edit: This ended up being a really dumb fix. My test equipment has a minimal amount of RAM and I allocated it all for use to the Windows VM I was trying to pass the GPU to. This worked fine when there is no PCI passthrough but as soon as I would add the GPU it would cause a kernel panic with no error messages in dmesg or /var/log/syslog and reboot the node. Downgrading to PVE 5.4 delayed the reboots long enough to start showing me some error messages that I could google.
Anyway don't be like me. Leave your PVE node some memory overhead when passing through PCI devices.
I was hoping someone could tell me where to look for errors with a problem I am having with GPU passthrough to a VM.
I made a post on Reddit's /r/VFIO with the details of what I have tried so far but really it seems I just need some logs and I am not sure where to get them. I haven't found anything useful in /var/log/syslog or dmesg and nothing is shown after starting the vm with

. Something is happening on the backend as power draw increases to the server and it's probably about 30 seconds before the reboot occurs but I was hoping someone could point me to where I should look for the cause of the issue.
