[SOLVED] container doesn't start :

[kloy]

hello,

i'd like to migrate a container form one PVE5.0-23 box to another using the same version (fresh new install).

So, i made a backup on the first node, and restore on the other one and the container doesn't start on the new node :

Job for lxc@100.service failed because the control process exited with error code.
See "systemctl status lxc@100.service" and "journalctl -xe" for details.
TASK ERROR: command 'systemctl start lxc@100' failed: exit code 1
​

if i try
lxc-start -n 100 -d --logfile nico.log -l debug

lxc-start: tools/lxc_start.c: main: 366 The container failed to start.
lxc-start: tools/lxc_start.c: main: 368 To get more details, run the container in foreground mode.
lxc-start: tools/lxc_start.c: main: 370 Additional information can be obtained by setting the --logfile and --logpriority options.​

here is the log

[dcsapak]

there is an updated package for pve-container which contains a fix for debian version detection, so please upgrade to the latest version

 

[kloy]

upgraded to 5.0-30 : it solved the problem.

you really do a great job...

Thanks.

I have exactly the same problem on Proxmox / debian 9.1. Upgraded to 5.0-30 but still doesn't work. Any ideas?

Turns out that in Proxmox 5 / Debian 9.1 I had to add dummy "address" and "netmask" lines to the bridge configuration or else the bridge will not be activated.

auto vmbr1
iface vmbr1 inet static
address 172.16.44.1
netmask 255.255.255.0
bridge_ports none
bridge_stp off
bridge_fd 0
