Just to precise that I'm also concerned whatever is the host (el7 or
el6) and I have many vms running on a single host (up to 15) and many
networks ( up to 10)
It is always the same : when vdsmd finished to take the totality of
memory, the host becomes unreacheable and vms begin to migrate. The only
way to stop this is to restart vdsmd.
