Hi everyone,

I'm experiencing an issue with Proxmox where, from time to time, after I install updates on Proxmox, my Debian 12 virtual machines start rebooting endlessly. This doesn't happen every time I update, but it's becoming a recurring problem, and I'm not sure what's causing it.

Has anyone else encountered this issue or know how to fix it? Any suggestions or guidance would be greatly appreciated!

Thanks in advance!
 
We have a similar problem on some non-production servers running pve-no-subscription repo.

windows and fedora vms seem to work fine
but after we upgraded proxmox and are running kernel ver. 6.8.12-1-pve
with pve-manager/8.2.4/faa83925c9641325 (running kernel: 6.8.12-1-pve)

the debian vm's inside as guest get only 895 mb of ram (but outside the proxmox web interface report the ram usage as normal.
this also makes the cpu goto 100% and the system is unusable
 
Got a enterprise subscription and switched to it... but still no luck as the packages of proxmox are updated with the test repo - any way to undo this and get the latest updates of enterprise repo only

this problem has come up only after the recent upgrade to proxmox and the problem is only with debian vm that have 895mb of ram being reported inside the vm. see the screenshot attached below. this problem is specific to only debian 12. windows, fedora, ubuntu all report correct memory.

problem is all my production vm are running debian 12 so basicall we are stuck. any ideas.?

ok - update folks

problem only appears if you enable hotplug of ram/cpu - and only on debian (12 for sure - not sure about other versions)

wasted over 6 hrs to figure this out
