I currently have an issue where when we migrate more than one VM from the host that is the SPM to another host it will cause connectivity to the SPM Host to fail which the ovirt engine then sees the host being down. It then reboots the SPM Host and stops all of the VM's running on there.
Our setup
Nodes: Fedora 18
em1: ovirtmgmt (mgmt, storage and migrations)
em2: VM network trunks
Engine: Fedora 17 (will be upgrading that to fedora 18 shortly)
Both NICS are 1 GB. The storage is NFS which is on the same VLAN and subnet as the hosts. The ovirt-engine is on a standalone server but is NOT on the same vlan/subnet yet.
Is this normal behavior for the SPM to have issue when migrating hosts to and from it? I don't have any further network interfaces to add to the hosts at this time (we are planning on adding a 2x 10GB card to each node in the future but we don't have that option at this time). Is there anyway to limit the number of active migrations and have the migrations be a lower priority traffic than others?
Thanks
Christian
