Correct,
coincidentally, there no instances of systemd-udevd going haywire either.

Hi,
just a quick update on the issue. The high amount of IOPS was
indeed due to having the hosted-engine on the EQL storage; we
worked around the issue by moving the hosted-engine to a gluster

And now there are no high amount of IOPS on the Gluster storage?
Y.

many calls to vdsm
that cause reloads of lvm data; this can cause increased io.
Can you attach vdsm and hosted engine agent logs showing the

Most of the VMs use barely any IOPS, however on our

So far so good. I then moved on to the oVirt host and installed the above packages (minus ovn-central) as well as the ovirt-provider-ovn-driver provided, started the ovn-controller service and ran # vdsm-tool ovn-config Executing the suggested checks I noticed that something didn't quite go as planned. Below is the /var/log/openvswitch/ovn-controller.log from the host machine. There are no firewalls involved (not even on the servers) and I also tried disabling SELinux but to no avail. Any ideas?
