This is for HVM guests.

I'm using LVM at my home setup for my DomUs, but having some issues with "mounting, umounting" the partitions inside the DomUs, as they are actually a disk image. Some of the kernels of my DomU's don't have LVM support at all, making it another issue.

Why don't we just use Extended Partitions? What is the added benefit of LVM to us? I read around that it also includes a little overhead. When it comes to extension, shringking, modification etc, extended partitions are just as good, as you can use many proved commercial products to resize your partitions easily.

Am I missing something here?
