crash on utopic ec2 instance

[Scott Moser]

Launched an instance on ec2.
Instance actually seems moderately fine, but then trying to create a bridge directly or indirectly will fail.
by indirectly, I mean:

$ sudo apt-get update -qy
$ sudo apt-get install lxc --assume-yes --quiet

$ sudo initctl status lxc-net
lxc-net stop/waiting
$ sudo cat /var/log/upstart/lxc-net.log
add bridge failed: Package not installed
Missing bridge support in kernel
lxc-net stop/pre-start, process 4453
add bridge failed: Package not installed
Missing bridge support in kernel
lxc-net stop/pre-start, process 4509

Did this issue happen on prior releases, or is it new with the 3.16 kernel?

[Serge Hallyn (serge-hallyn)]

It doesn't currently happen on trusty images, if that helps. I have no idea when it was introduced.

Are you able to install regular amd64 kernels with dpkg on the test environment? If so, we can perform a bisect and identify which commit introduced this?
