Subject [jira] [Commented] (CLOUDSTACK-3535) No HA actions are performed when a KVM host goes offline
Date Tue, 06 Aug 2013 08:06:47 GMT


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) :-)
