Title:
container does not receive IP address after 15.04 upgrade
Status in lxc package in Ubuntu:
Triaged
Bug description:
Perhaps this is an upgrade issue, perhaps it is a installation issue.
In either case, there should be more information about upgrading lxc.
After upgrading to Ubuntu 15.04, my container no longer started.
After upgrading, I had to remove the following line from the config
file for my container:
lxc.network.link = lxcbr0
Here is the attempt at starting before commenting out the line:
kevin@nereocystis:~$ sudo lxc-start -F -n escale_build
lxc-start: conf.c: instantiate_veth: 2660 failed to attach 'vethTCPSQO' to
the bridge 'lxcbr0': Operation not permitted
lxc-start: conf.c: lxc_create_network: 2943 failed to create netdev
lxc-start: start.c: lxc_spawn: 914 failed to create the network
lxc-start: start.c: __lxc_start: 1164 failed to spawn 'escale_build'
lxc-start: lxc_start.c: main: 344 The container failed to start.
lxc-start: lxc_start.c: main: 348 Additional information can be obtained by
setting the --logfile and --logpriority options.
After commenting out this line, the container starts, but no IP address is
assigned in the container.
But no IP address was assigned:

done.
Eventually, I purged lxc, and reinstalled it, with the same results.
I also tried creating a new container from scratch using the
instructions in:
https://help.ubuntu.com/lts/serverguide/lxc.html#lxc-network
sudo lxc-create --template download --name u1
Again, no IP address.
