Hi,

I've a problem with starting a LXC container.

Code:

Proxmox version: 4.2.23

Thanks for helping me.
 
please post the complete output of "pveversion -v" and the containers configuration ("pct config 101")

Do the paths ("/data/www", "/data/logs") that you try to bind-mount into the container really exist? Note that symlinks are forbidden for the source of bind mounts..
 
"/data/www", "/data/logs" does not exist anymore (I moved the container on new server)

Indeed, when I delete the twos path, I can start the container.

The error code is not really explicit.

lxc in general is not really helpful regarding error messages, especially for failing hooks...
