Re: [Xen-devel] HOWTO use Virtual Hard Disk - VHD with Xen domUs?

[Thiago Camargo Martins Cordeiro <thiagocmartinsc@xxxxxxxxx>]

Hi!

 You believe that I'm already using it without seeing it was what I'm looking for!? That is funny!

 I have a domU with a Logical Volume for its root partition and sometime ago, I need to boot a "clone" of the domU, so I just made a LVM Snapshot, configure another VM (with another MAC Addres, etc) using the snapshot as read-write root partition...

 I didn't realise what I have in my hands!

Thanks!

Hi Thiago,

I'm not sure if VHD is (or will be) supported with Xen. Someone else might be
able to answer that question.

But why not look into using LVM and COW (Copy-On-Write) volumes?
This would allow you to create a base image and link the Guests to COW-volumes
based on this image.

The end result would be the same and LVM is a proven technology.
