Haven't tried it by myself, but I am quite sure you need to recompile the whole binaries (qemu, qemu-img and so on). Just to be safe... And as how to use it: 1. do snapshot e.g using "savevm" command in qemu monitor 2. I think it's better to shutdown the guest first to prevent in flight disk I/O during snapshot copy, then execute: qemu-img convert -f qcow2 -O qcow2 -s snapshot_name src_img bck_img where: -s is the snapshot name of the result image. This will contain ONLY your snapshots... src_img_bck_img: your current disk image filename which contains your snapshot. -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com
