[Bug 1373334] [NEW] Fail to revert VM snapshot properly after copying to the other host

[Kirill Omelchenko]

Public bug reported:

Both hosts configuration:
OS: Ubuntu 14.04.1 LTS
libvirtd (libvirt) 1.2.2
qemu-kvm 2.0.0+dfsg-2ubuntu1.3

Steps to reproduce:
(on Host-1)
1. Create VM with next configuration: http://pastebin.com/bsfG5tFZ
2. Setup CentOS 6.5
3. Create snapshot of running VM using next command:
	$ virsh snapshot-create-as [vm-name] [snapshot-name] --memspec snapshot=internal
4. Backup VM xml:
	$ virsh dumpxml [vm-name] > [vm-name].xml 
5. Backup VM snapshot xml:
	$ virsh snapshot-dumpxml [vm-name] [snapshot-name] > [snapshot-name].xml 
6. Backup networks used by VM:
	$ virsh net-dumpxml [net-name] > [net-name].xml
7. Backup images used by VM.
8. Copy all backup data to Host-2
(on Host-2)
1. Restore networks:
	$ virsh net-define [net-name].xml
	$ virsh net-start [net-name]
	$ virsh net-autostart [net-name]
2. Restore images to appropriate directories.
3. Restore VM:
	$ virsh define [vm-name].xml
4. Restore snapshot:
	$ virsh snapshot-create --redefine [vm-name] [snapshot-name].xml
5. Revert snapshot:
	$ virsh snapshot-revert [vm-name] [snapshot-name]

Expected result:
Snapshot is in running state, VM is in the exact state of snapshot taken on Host-1 after revert.

Actual result:
Snapshot is in running state, VM is in running state, BUT is in just started state and is booting.
