Subject [jira] [Commented] (CLOUDSTACK-3535) No HA actions are performed when a KVM host goes offline
Date Thu, 25 Jul 2013 02:31:48 GMT

    [ https://issues.apache.org/jira/browse/CLOUDSTACK-3535?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13719160#comment-13719160

Bryan Whitehead commented on CLOUDSTACK-3535:
---------------------------------------------

I just wanted to add that his bug is seriously a huge problem. Effectively 4.1/kvm is completely
broken as is if a host goes down - when a router system vm is sitting on a dead host all VM's
depending on that router are completely hosed. The work around to this is hacking the DB live
to force the router systemvm to be Down.

More details of my experience with this bug here:
