Hi Forum,

I noticed that internal/external qcow2-snapshots are not fully implemented yet: wiki-libvirt
Are there any other snapshots solutions for kvm/qemu that offer create/delete/refert? One way as far as I understand would be to use epel-virtualization_preview_repo and update to newer stuff...
For now I simply copy img-files(qcow2) to have a fall-back before making critical changes?

CODE
root:~# lsb_release -as
:base-4.0-amd64:base-4.0-noarch:core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch Scientific "Scientific Linux release 6.5 (Carbon)" 6.5 Carbon

as I discovered libvirt is not used to take snapshots...

but qemu-img can; also qcow2 supports copy-on-write which is what I'm looking for. I haven't tested it so far.
