Hi, I think the usage of sheepdog snapshot/cloning was a bit confusing, and I made it more intuitive for those who are familiar with qemu.
This patchset is for the master branch, and depends on the server patch I sent one minute ago. Any feedback is welcome! Thanks, Kazutaka Morita == Usage before/after applying this patchset: - create a snapshot of a VM image [before] $ qemu-img snapshot -c name sheepdog:[vdi name] (the argument of -c option has been ignored) [after] $ qemu-img snapshot -f sheepdog -c [tag name] [vdi name] - create a clone image (only from a sheepdog image) [before] $ qemu-img create -f sheepdog -b sheepdog:[base vdiname]:[base tag] [vdiname] [after] $ qemu-img create -f sheepdog -F sheepdog -b [base vdiname] -o tag=[base tag] [vdiname] or $ qemu-img create -f sheepdog -o backing_fmt=sheepdog,backing_file=[base vdi],tag=[base tag] [vdiname] - use a snapshot image as a backing image of other formats (note: this feature isn't well-tested and may have a fundamental problem) [before] $ qemu-img create -f qcow2 -b sheepdog:[base vdiname]:[base tag] [filename] [after] $ qemu-img create -f qcow2 -F sheepdog -b [base vdiname] -o tag=[base tag] [filename] or $ qemu-img create -f qcow2 -o backing_fmt=sheepdog,backing_file=[base vdi],tag=[base tag] [filename] - boot using a snapshot image [before] $ qemu-system-x86_64 --drive format=sheepdog,file=[vdiname]:[tag] [after] $ qemu-system-x86_64 --drive format=sheepdog,file=[vdiname],tag=[tag] -- sheepdog mailing list sheepdog@lists.wpkg.org http://lists.wpkg.org/mailman/listinfo/sheepdog
