2. Reboot comute, virt node (node-2 + node-10)
After the reboot, nova-compute service is disabled with error in nova-compute: [1]
<179>Feb 10 06:32:04 node-2 nova-compute: 2016-02-10 06:32:04.948 4820 ERROR nova.virt.
Libvirt error: [2]
So nova-compute service try to start before the ovs port is created
[1] http://
[2] http://
Workaround:
1. Wait a period of time (5-10 min) till the socket /var/run/
2. Restart nova-compute service on node-2:
service nova-compute restart

Moreover, libvirt is not able to communicate with openvswitch database(to recreate port), cause openvswitch service was not able to start in time. openvswitch/ ovs-vswitchd. log file: 10T07:49: 11.254Z| 00001|vlog| INFO|opened log file /var/log/ openvswitch/ ovs-vswitchd. log 10T07:49: 11.258Z| 00002|reconnect |INFO|unix: /var/run/ openvswitch/ db.sock: connecting... 10T07:49: 11.258Z| 00003|reconnect |INFO|unix: /var/run/ openvswitch/ db.sock: connected
