Unfortunately I didn't implement all the possible formats for this as there's a lot of them and one of the missing pieces is the colon syntax for RBD volumes. I'll try to come up with a patch for this that will allow to recognize the RBD volume as a remote one where libvirt isn't able to access it and allow to start the VM. > > I was under the impression that qemu could work with ceph-based backing stores, so is there something I should run first, or files that I should patch, or ... ??? I am running libvirt 1.2.9. Thanks for any assistance you can provide. Qemu is able to handle those. Libvirt currently doesn't support the syntax. > > Lyssa > Peter > -- > libvir-list mailing list > libvir-list(a)redhat.com > https://www.redhat.com/mailman/listinfo/libvir-list >
