Title:
crash on utopic ec2 instance
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
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
