</div>Note that this VM (and some other VMs listed in your script) uses<br>
logical partitions. In this case just saving a copy of MBR will not<br>
be enough to save partition layout - MBR describes only 4 primary<br>
partitions, and restoring just MBR will not restore extended<br>
partitions.<br>
<br>
One way to backup the complete partition layout is by saving also<br>
the output of "sfdisk -d $device"; the resulting file can be used as<br>
input to sfdisk to restore all partitions, including logical ones.<br>
Saving MBR is still needed together with sfdisk, because it saves<br>
the boot code (used for HVM) and CHS geometry information (which can<br>
be used during boot in some cases).<br>

<br># FAQ<br># Q: Why do I want to write this cloning script when there are many open source cloning software available?<br># A: I am previously using Clonezilla. It is a very good cloning software. However, it could not detect all the<br>
# virtual machines in my LVM2 logical volumes and had to fall back on using dd to image all my domUs,<br># which resulted in an enormous 300 GB (!) backup image set and an extremely lengthy cloning process of <br># 7 hours. Clonezilla is very good for LVs which only contain filesystems, but not for LVs which contain<br>
# virtual machines with MBR, partition geometries and full fledged operating systems. It is very diffcult<br># to image nested logical volumes, i.e. logical volumes within logical volumes. And the PV within a LV is <br>
# the barrier. So it is not Clonezilla's fault. Anybody who knows how to activate all the logical volumes<br># of all the volume groups within LVM2 physical volumes inside a logical volume hosting a virtual machine,<br>
