I dd'd the LV from a snapshot to an empty LV on a different VG with identical extents like this: dd if=/dev/vgsnapshotsource/win2k8-snapshot of=/dev/vgtarget/win2k8-target I'm a little confused by what you mean by "partition" and disk in this context. There is the LV container created, a partition, but also a volume and presented as a "disk" to the Windows vm. Then inside that LV, W2k8 is installed, and that partitioned inside that LV two logical drives which were then formatted NTFS by the W2k8 installation. So, I dd'd the LV "partition" but wasn't I also dd'd Window's "perception" of its disk? Christopher G.

If you did the whole disk (verify with fdisk or something), you can use kpartx to add the LV as a disk and then mount the partitions that are created. >
