Title:
lxd won't restart a container
Status in linux package in Ubuntu:
Incomplete
Bug description:
During the upgrade of a container from xenial to bionic, the container
stopped working after the reboot.
In an manual attempt to start the container:
# lxc start juju-3fae13-25-lxd-6
error: Monitor is hung
There are no failures reported in lxd/lxc related log files
The dmesg does give some possibly related lines:
[24085329.749762] unregister_netdevice: waiting for eth2 to become free.
Usage count = 1
[24085339.874547] unregister_netdevice: waiting for eth2 to become free.
Usage count = 1

[24085370.329020] unregister_netdevice: waiting for eth2 to become free.

I could find that eth2 got renamed quite a few time:
