This issue first started while using Luminous 12.2.5, I upgraded to 12.2.7 and it's still present. This issue is _not_ present in 12.2.4.
With Ceph 12.2.4, using QEMU/KVM + Libvirt, I'm able to mount an rbd image using the following syntax and populated xml:
'virsh attach-device $vm foo.xml --persistent'
xml contents:
<disk type='network' device='disk' snapshot='no'>
<driver name='qemu' type='raw' cache='writeback' discard='unmap'/>
<source protocol='rbd' name='libvirt-pool/foo'>
<host name='X.X.X.X' port='xxxx'/>
<host name='X.X.X.X' port='xxxx'/>
<host name='X.X.X.X' port='xxxx'/>
</source>
<auth username='libvirt'>
<secret type='ceph' uuid='XXXX'/>
</auth>
<target dev='sdb' bus='scsi'/>
<shareable/>
</disk>
I receive this error:
~# virsh attach-device $vm foo.xml --persistent
error: Failed to attach device from foo.xml
error: internal error: unable to execute QEMU command 'device_add': Property 'scsi-hd.drive' can't find value 'drive-scsi0-0-0-1'
I've tried different things with the XML, but nothing seems to work, always failing with the above error. This does _not_ happen with our cluster running 12.2.4, the same exact command with a cluster using an identical configuration (for all intents and purposes).
Any thoughts? Hard to believe I'm the only one to hit this if it's indeed a bug, but I haven't found anyone else having the issue through interweb searches.
