Title:
centos7 train vm live migration stops network on vm for some minutes
Status in neutron:

Status in neutron train series:

Bug description:
Hello, I have upgraded my centos 7 openstack installation from Stein to Train.
On train I am facing an issue with live migration:
when a vm is migrated from one kvm node to another, it stops to respond to
ping requests from some minutes.
I had the same issue on Stein and I resolved it with a workaround suggest by
Sean Mooney where legacy port binding was used.
On train seems there aren't backported patches to solve the issue.
I enabled debug option on neutron and here there is the dhcp-agent.log from
the exact time when the live migration started:
http://paste.openstack.org/show/805325/
Here there is the openvswitch-agent log from the source kvm node:
http://paste.openstack.org/show/805327/
Here there is the openvswich agent log from the destination kvm node:
http://paste.openstack.org/show/805329/
I am using openvswitch mechanism driver and iptables_hybrid firewall driver.
Please any help will be appreciated
Ignazio
