This patch adds the support for reporting the image end offset (in

where the destination is a block device in order to find the first

Hi,
recently I've been working on live block migration combining the live
snapshots and the blkmirror patch sent by Marcelo Tosatti few months ago.

Hi,
oVirt, and more specifically VDSM, is currently implementing the live
snapshot feature using the API/commands provided by libvirt and qemu.
It would be great if you could review the design and the current open
issues at:
http://ovirt.org/wiki/Live_Snapshots
Thank you,

Add the new option [-n] for snapshot_blkdev to avoid the image creation.
The file provided as [new-image-file] is considered as already initialized
and will be used after passing a check for the backing file.

In some situations might be useful to let qemu use an image that was
prepared for a live snapshot.
The advantage is that creating the snapshot file outside of the qemu
process we can use the whole range of options provided by the format
(eg for qcow2: encryption, cluster_size and preallocation).
It
storage within
certain timeouts is critical.
This patch adds the option to choose a cache method when writing
disk images.
