From: Jes Sorensen <jes.soren...@redhat.com> Hi,
This set of patches re-factors img_create() and moves the core part of it into block.c so it can be accessed from qemu as well as qemu-img. The second patch adds basic live snapshots support to the code, however only snapshots to external QCOW2 images is supported for now. QED support should be trivial once the QED patches go into upstream. The last patch fixes a small gotcha which is present in the old code as well. Try to catch cases where a user tries to create an image with itself as the backing file. QEMU does 'interesting' things when you do this..... Many thanks to Kevin for his help with block layer internals! Cheers, Jes Jes Sorensen (3): qemu-img.c: Re-factor img_create() Introduce do_snapshot_blkdev() and monitor command to handle it.
