Along with what Cole said, here is some more explanation into revert/deletion of external snapshots (written by Eric Blake) http://wiki.libvirt.org/page/I_created_an_external_snapshot,_but_libvirt_won%27t_let_me_delete_or_revert_to_it And, also look up the archives of 'libvirt-users' mailing list for similar questions -- there's lot of useful info there too. -- /kashyap _______________________________________________ virt mailing list virt@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/virt
