Open Stack

Hello, 

When I tries to use devstack and quantum rc3 code base ( single node environment in a VM, OpenVSwitch Plugin), the launch instance failed with "libvir: Network Filter error : Network filter not found:: Could not find filter 'nova-instance-instance-00000001-fa163e31fb45" error message in Nova.

devstack's localrc:
disable_service n-net
enable_service q-svc
enable_service q-agt
enable_service q-dhcp
enable_service quantum
LIBVIRT_FIREWALL_DRIVER=nova.virt.firewall.NoopFirewallDriver

this is the instance's libvirt config from nova's log file:
