Hi,

I checked the logs on my hypervisor that contains also the overt-engine (self-hosted) and I see strange unknown libvirterrors that come periodically in the vdsm.log file. The storage is glusterFS running on the hypervisor as well, one NFS export domain and an ISO domain. A NFS domain from another place is in maintenance mode.

I am running oVirt 3.5.3.

Thank you for any pointers as to where to start fixing this issue.
