      Description

      ovs-switchd process randomly uses >300% CPU until restarted, which has a severe impact on the XenServer host and all VMs running. To resolve the issue, either reboot the host or execute "systemctl restart openvswitch". The latter command is the preferred recovery option as this does not introduce downtime and can be done at any time without disrupting service.
