the issue does not happen when using the iptables_hybrid firewall driver.
it only happens when using the the openvswtich driver.
the underlying root cause is a race condition between libvirt and neutron that only
happens when libvirt adds the tap device to ovs. when using the iptables_driver
that does not happen.
so unless there is a seperate issue in the neutron l2 agent the iptabeles driver is unaffected.
