[SOLVED] Debian LXC doesn't start after power outage (pve node reboot ok)

[Carizoeuf]

Hi,

I am new to LXC containers and set up a Debian 11 (official template) LXC for haproxy.

I don't have any UPS at the moment and suffered two power outages on two different days. When the power outage is short, my hardware reboot when the power come back and Proxmox and all my VM restart without any problem.

But each time, the LXC doesn't restart, I had to do it manually. As it will be my new reverse proxy with haproxy, it is inconvenient.

I have read some similar cases on the forum without finding the solution.

Here are some details:

The Proxmox node Debian is up to date.

Thank you for your help.

I might be completely misunderstanding your issue but have you tried enabling Start at boot in Options of the container? That would start the container when Proxmox starts (or reboots).
EDIT: I did not see onboot: 1 in the configuration but maybe it's in the parent (in which case my reply is useless)?

Hi @leesteken
No, you were right, it was this simple!
I am new to LXC containers and did not see this option.
Thank you!
