Lennert den Teuling commented on CLOUDSTACK-3535:
-------------------------------------------------
Hi Edison, in my opinion this would be sufficient. I'm not familiar with the
XenServerInvestigator but if i expect it sends some kind of heartbeat for
example using (shared)storage this would definitely be enough to determine a
host is down.
Like i said before i would love to see a simple IPMI-ish integration in the
kvmfencer so CS is able to poweroff the host. I don't know if somebody has
already taken a look at this but i think i can find somebody who will (if i ask
nicely) :-)
