[ovs-dev] OVS and namespaces

Hi,
When Quantum is using OVS and namespaces there are problems when 
namespace is being deleted. More specifically this is when a default 
gateway is assigned to an interface that is used by the OVS. A simple 
way of reproducing this is:

sudo ip netns exec<name>  ip route del ...
sudo ip netns exec<name>  ovs-vsctl del-port...

 From this moment on one is not able to access the namespace. The 
problem does not occur when the traditional linux bridges are used.

Has anyone encountered this before?

Thanks
Gary
