This is my post from serverfault[1] in verbatim: While trying to get a cloned disk running from my OS snapshot I run into the problem that Libvirt cannot see existing images cloned from a snapshot. Created via: # rbd -p vmdisks clone vmdisks/coreos_2023@base vmdisks/coreos00.disk The base image has the one snapshot 'base' and is protected. The cloned disk is created just fine: # rbd -p vmdisks info coreos00.disk rbd image 'coreos00.disk': size 8.49GiB in 2174 objects order 22 (4MiB objec...
