[Bug 1401148] Re: Re/starting an lxc container corrupts all network namespaces on the same physical host
I had assumed that "test-test" was a type and saw the same result after
starting the container with "test", too. So somehow starting an lxc
container seems to have an impact on netns. Not sure whether the
apparmor message may relate which seems to trigger when lxc-start tries
to mount /run/netns.

Title:
Re/starting an lxc container corrupts all network namespaces on the
same physical host
Status in lxc package in Ubuntu:
New
Bug description:
Context: Neutron gateway north/south routing server which manages a
large number of network namespaces; also hosts a few LXC containers
for misc lightweight control plane services.
Problem: If I restart one of the lxc containers, all of the
namespaces get corrupted in someway; attempting to exec anything in
any namespace fails with:
seting the network namespace "qrouter-4b575c81-39bb-439f-81e1-e59e3759a287" failed: Invalid argument
