Marcus Sorensen commented on CLOUDSTACK-600:
--------------------------------------------
I wasn't going to mention that immediately since I see there are
'transient' properties for disks as well, and that makes them not save
the changes, reverting to the original backing file on reboot. I
wouldn't want to create a VM in 'transient' state without making sure
I understood if that also applied. The domainCreateXML seems to be the
transient VM mode according to this:
http://wiki.libvirt.org/page/VM_lifecycle#Transient_guest_domains_vs_Persistent_guest_domains
Other than checking that, domainCreateXML sounds like it's the way to
go if it keeps us from remembering the VM outside of cloudstack.

> When rebooting KVM local storage VM host, libvirt definitions deleted

> Components: KVM

> This is definitely the case in 3.0.3, and I don't think the relevant code has
> been touched since.
> 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.
