Is it possible that only one original disk is involved in virt-resize? virt-resize is part of libguestfs, and as such is not maintained on this list. You'll get better answers about why virt-resize does not support in-place resizing by asking on that list. But the answer probably involves the fact that virt-resize is doing MUCH more than resizing the block device - it is also copying entire filesystems from the old location to the new resized location for optimal initial placement. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
