When systems go 'crazy' there is no guarantee that they will be completely
unresponsive. HA VMs should be fine, but regular VMs won't be restarted as the
engine won't know if the host is dead or not (and no fencing is configured to
guarantee that).
Also, storage tasks could fail if that host is

Hi,
For example, in situation where host:
* laggy
* network laggy
or another manager <-> host connectivity issues - ovirt-engine can't determine
what with host actually:
* host stuck
* host unreachable
* me (engine) unreachable
* other lossy, lags, etc
another chances for enginte to determine
I think that the following documentation explains it far better than a single
person can do:

If your Host is stale and is having thr SPM role -> some tasks will fail.Also,
the VMs on such host won't be recovered unless VM HA is enabled (with storage
lease).
For prod, I would setup that.Keep in mind that the fencing is issued by another
host in the cluster, so you need minimum 2 hosts in
12 matches
