Open Stack

use_namespaces has no effect, lbaas agent in grizzly always relies on
namespace support.

Could you execute the failing command manually?
That needs to be done after you create a vip for the pool.
The command should look like this:
sudo quantum-rootwrap /etc/quantum/rootwrap.conf ip netns exec
qlbaas-e10951cd-4cca-4ba4-acc0-0ccde6817029 haproxy -f /var
/lib/quantum/lbaas/e10951cd-4cca-4ba4-acc0-0ccde6817029/conf -p
/var/lib/quantum/lbaas/e10951cd-4cca-4ba4-acc0-0ccde6817029/pid

<e10951cd-4cca-4ba4-acc0-0ccde6817029> should be replaced with actual
pool_id
Could you also verify that path and file /lib/quantum/lbaas/e10951cd-
4cca-4ba4-acc0-0ccde6817029/conf exist?

Thanks,
Eugene.
