trying to launch. when I made a second image from a different
source and loaded into Ceph (and after a reboot of the VM host
in question) things just worked. In another post someone had said it
could be a locking issue--that is possible
Thanks for responding.
Others have told me the same--that libvirt is doing its thing in user
space. The process of OpenNebula actually clones a copy of the image
so this image was freshly created and there's no way it could
have been mapped elsewhere.
In other news--by just taking the simpl
