Is deconfiguration on stop of an lxc instance not working anymore? |
[Impact]
Users of VLANs with LXC containers will see kernel BUGs when starting and stopping containers.
[Test Case]
- In trusty, install lxc and vlan.
- Edit /etc/lxc/default.conf as follows:
lxc.network.type=vlan
lxc.network.vlan.id=10
lxc.network.flags=up
lxc.network.link=eth0
lxc.aa_profile = unconfined
- Setup LXC container
sudo lxc-create -t download -n u1 -- --dist ubuntu --release trusty --arch amd64
- Run the following until you see the failure:
lxc-start --name u1 -d
lxc-stop --name u1
