Andrew Bayer commented on CLOUDSTACK-600:
-----------------------------------------
Next time I get to a machine that I need to reboot, I'll put it in DEBUG. And
yeah, your description of the issue is right. Migration shouldn't be happening
here, since we're in local storage. I'm wondering if the storage for the VMs is
getting deleted at reboot time...

> When you reboot a VM host running KVM local storage VMs, the VMs are deleted
