Hello,

i was doing some tests on how ovirt reacts to host failures. I've seen
that in case of network failure an host stais in non responding state
for 60 seconds before being fenced. Event log reports:

Host XXX is not responding. It will stay in Connecting state for a
grace period of 61 seconds and after that an attempt to fence the host
will be issued.

Does this value can be set to a lower/different value?

I've seen that this becomes of at least 1 minute for restarting the
HA-protected vms of that host. If that host, additionally, hosts also
the engine, a vm (different from the engine) will start not before 6
minutes, which is a very long time.
