Hi,I just tried to start a VM with libvirt with the following disk: <disk type='network' device='disk'> <driver name='qemu' type='raw' cache='none'/> <source protocol='rbd' name='rbd/8489c04f-aab8-4796-a22a-ebaa7be247a7'> <host name='31.25.XX.XX' port='6789'/> </source> <target dev='vda' bus='virtio'/> </disk> That fails with: "Operation not supported" I tried qemu-img: qemu-img info rbd:rbd/8489c04f-aab8-4796-a22a-ebaa7be247a7:mon_host=31.25.XX.XX\\:6789 Same result. I then tried: qemu-img info rbd:rbd/8489c04f-aab8-4796-a22a-ebaa7be247a7:mon_host=31.25.XX.XX\\:6789:auth_supported=none And that worked :) This host does not have a local ceph.conf, all the parameters have to come from the command line. I know that recently auth_supported defaults to "cephx", but that now break the libvirt integration since it doesn't set auth_supported to explicitly none when no auth section is present. Should this be something that gets fixed in librados or in libvirt?
Thought about it, this is something in libvirt :)
If it's libvirt, I'll write a patch for it :)
Just did so, very simple patch: https://www.redhat.com/archives/libvir-list/2012-June/msg01119.html
