RE: [Xen-users] migrate file-based vm to lvm?

["Nick Couchman" <Nick.Couchman@xxxxxxxxx>]

Yes, you should be able to create a new LVM volume and then run something like:
dd if=/path/to/dis/file of=/dev/volumegroup/volume

The LVM volume needs to be either exactly the same size as the file or slightly larger, and there may be some rounding differences, so you may end up with extra space on the volume.

If I am thinking correct here you could dd it to an lvm partition?

Can anyone confirm? I have yet to try this as I find it easier to manage corporate vm structure using image files (better across the network).

Subject: [Xen-users] migrate file-based vm to lvm?



I recently upgraded storage on our (first) xen server and would like to
migrate the file-based vms I have in play to lvm-based storage... Can anyone
point me in the right direction? 

Is there a way to mount a vm image file like I would using a iso image and a
loopback device? Each vm's disk file contains a partition table with root
and swap partitions... In retrospect I wish I'd set these up independently!

Thanks for any help!

Cheers,
Tim
