FYR, I have done some similar tests several weeks ago to test the host HA functionality.
CS 4.0.2 + XenServer 6.0.2: Works as expected. HA-enabled VMs (including System VMs) were automatically restarted on HA-dedicated hosts. CS 4.1.0 + XCP 1.6: No HA thing happened at all much like what you described. The states of VMs and hosts were just like before, but inaccessible. CloudStack just couldn't seem to detect the host down! CS 4.1.1 (git) + XenServer 6.1: Works as expected. Just like the first case. I didn't have time to try other combinations, and the logs are gone, but I guess the problem more likely has to to with XCP support than CS 4.1.0. ------------------------------------------------------------------------------------------- Yu-Heng (Ryan) Lei, Associate Reasearcher Chunghwa Telecom Laboratories / Cloud Computing Laboratory [email protected]<https://email.cht.com.tw/owa/redir.aspx?C=-wE1FEC3G0SWYpVkiWo8SsDdf3ZqO9AIuAPTzRnFYCUi-z4YljtI_hyVKkNHfn9F1Bn-vUWJnQ4.&URL=mailto%3aryanlei%40cht.com.tw> or [email protected] On Thu, Jul 25, 2013 at 2:07 AM, Kirk Jantzer <[email protected]>wrote: > Can someone "explain like I'm 5" how HA in CS should work?
