[ovirt-users] ovs-vswitchd high cpu usage

Hi, Just updated last week ovirt hosts from 4.0.6 to 4.1.1 and I noticed ovs-vswitchd high cpu usage, around 100%. My cluster switch type is in legacy mode, so I decided to stop ovs-vswitchd process on each ovirt host. This morning, when trying to run a new VM and I've got the following error message : Exit message: (21, 'Executing commands failed: ovs-vsctl: unix:/var/run/openvswitch/db.sock: database connection failed (No such file or directory)') Even if the cluster is in legacy mode, it seems that ovs-vswitchd needs to be up and running for vdsm. So, how can reduce the cpu usage of ovs-vswitchd process ? Regards, Arnaud
