Title:
Re/starting an lxc container corrupts all network namespaces on the
same physical host
Status in linux package in Ubuntu:
Confirmed
Status in lxc package in Ubuntu:
Confirmed
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
seting the network namespace "qrouter-1f5e26df-f8c5-4246-9485-3f9df8e39c40"
