Title:
ML2 : hard reboot a VM after a compute crash
Status in neutron:
Won't Fix
Status in openstack-manuals:
Fix Released
Bug description:
I run in multi node setup with ML2, L2-population and Linuxbridge MD,
and vxlan TypeDriver.
I start two compute-nodes, I launch a VM, and I shutdown the compute-
node which host the VM.
I use this process to relaunch the VM on the other compute-node :
http://docs.openstack.org/trunk/openstack-
ops/content/maintenance.html#totle_compute_node_failure
Once the VM is launched on the other compute node, fdb entries and
neighbouring entries are no more populated on the network-node nor on
the compute node
