Debian based container crash the host and reboot

troublestarter · Jan 7, 2023

Hi Guys

Every time we try to use a debian container in proxmox, the console of container is blackscreen.
We try to stop it or anything else, the host crash and reboot.
We used ovs switch and migrate to linux bond but same issue.
Don't crash with centos9 CT for exemple.

Environnement :
Proxmox 7.3.3
Kernel version 5.15.74-1-pve #1 SMP PVE 5.15.74-1

Below the syslog :

No one used to have issues with DEBIAN CT that crash the host ?

I tried on an other host in the cluster, no crash actually but black screen on CT debian based :

Finally, it's works with an fixed IP address... Not with DHCP.
No more blackscreen.

troublestarter · Jan 10, 2023

Seems only the IPv6 DHCP broke the CT.

No one used to have issues with DEBIAN CT that crash the host ?

Yes, we have the exact issue since few month. We solved pining kernel 5.13. But seems that openvswitch version has a problem with LXC and 5.15

Not only OVS, same issue with standard linux networks

I have checked the two cases.

We checked both and with linux bridge no issues. Trace of syslog and kern.log: https://paste.tecnocratica.net/view/1e885b69#KJPnCxSB5XDSfjOhpa3sQM6cGoCe7EKs

Testing with a simple script to up and down the CT. It random crash on any kernel higher than 5.13 with OVS.

Only thing related to this issue doing a little research is this commit patch: https://git.kernel.org/pub/scm/linu.../?id=b83d23a2a38b1770da0491257ae81d52307f7816

Does anyone know if this is still an issue or if it was corrected in Kernels 5.16 or higher?

We have not encountered such problems in PVE 8.2.x. I would recommend to use the Kernel 6.11.x or newer.
