A follow up to this issue, I found out that the lxc package from
ubuntu-lxc/stable (1.0.0~alpha2+) can't be use as-is on current LTS
(precise) due to various issues (e.g. apparmor problem, containers detected
as not started if started automatically on boot but behaves correctly when
started manually, etc) which I haven't had time to track further.
As a workaround, I've created a ppa with lxc from precise-backports
(0.8.0~rc1+), plus the above patch, on
https://launchpad.net/~ubuntu-ppa/+archive/lxc-lts
I then use this on container's config file:
lxc.network.veth.pair=v-c1-e0
lxc.network.script.down = /var/lib/lxc/c1/network_down.sh
... and the script contains this
#!/bin/bash
/sbin/ip link del v-c1-e0 || /bin/true
Tested with:
- lxc-start
- lxc-stop, then lxc-start again
- "reboot -f" inside the container
Not ideal, but acceptable for my needs.
