Subject [jira] [Commented] (CLOUDSTACK-600) When rebooting KVM local storage VM host, libvirt definitions deleted
Date Thu, 07 Feb 2013 09:07:12 GMT

    [ https://issues.apache.org/jira/browse/CLOUDSTACK-600?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13573323#comment-13573323

Rohit Yadav commented on CLOUDSTACK-600:
----------------------------------------

So, to fix this issue we'll need a daemon that persists data, local storage (of vms) running
on the host, or is there a way to fix it withing libvirt, or possibly fixing in upstream?

> When you reboot a VM host running KVM local storage VMs, the VMs are deleted from libvirt.
I presume this is due to CloudStack thinking it's migrating them away from the host, but obviously,
given that we're on local storage, it's unable to do that. The result is that the VMs are
not able to be restarted when the host comes back online.
