Public bug reported: 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.
