Description
Across all our hosts (20~) there are many Openvswitch processes running on the dom0s that regularly use a lot of CPU resources (between 30-100% of one Xeon E5-2660 v2 core).

We went to check the openvswitch logs but they're empty and contain nothing:

[root@s1-b8 log]# file /var/log/ovs-vswitchd.log /var/log/ovs-vswitchd.log: empty
and because journalctl has been set not to log in XenServer 7 I can't get any logs or metrics from systemd regarding the service (See XSO-543)
This occurs both on XenServer 6.5 SP1 and 7.0
