I don't think that this is the cause, because as far as I understand the error, Xen does not even try to look for the kernel or what ever. On the first access on it's image, located on the RBD, it says "file not found", otherwise it would say s.th. like "kernel not found". So any other ideas? -- kind regards, thg _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
