Some extra info:

I see a very high load on all hosts without any VM started:

The strange thing is that I can fairly mount my NFS share where my
VM's and HE is on, this is no issue. But in some way vdsmd fails and
the RHEV mounts, which ovit makes dies and a df -h times out.


I'm very curious what is going on here.
