Description of problem:

when defining a RBD disk option using virsh one needs to add monitor_ip and secret key, this option is not required when starting the vm using qemu-kvm cli on ceph client, Also sometimes mon ip's can change, I believe this option should be simplified and one should just provide the rbd disk image name in case of ceph clients.

<disk type='network' device='disk'>
        <source protocol='rbd' name='libvirt-pool/new-libvirt-image'>
                <host name='{monitor-host}' port='6789'/>
        </source>
        <target dev='vda' bus='virtio'/>
</disk>

</source>
<auth username='libvirt'>
        <secret type='ceph' uuid='9ec59067-fdbc-a6c0-03ff-df165c0587b8'/>
</auth>
<target ...

Comment 2 Peter Krempa 2016-03-24 13:22:39 UTC

I think that would not be a desired thing to do.

Allowing to use the defaults for ceph that are taken from the system-wide config file will make configurations unstable when the config file changes or the machines are migrated to a different host with a different config. Keeping the data in libvirt enforces that the configuration of a VM is stable in regard to external influence.

I'm closing this as WONTFIX.
