I was investigating the RBD support as well and in order to add proper
support for it into virt-manager we need to add support for secrets.
Right. But I was starting with the assumption that a "storage admin" setup an
rbd-based pool, necessary secrets, etc. Then user creating a new VM could select
existing volumes in the pool or create new ones at step 4/5 of the VM creation
wizard. Currently a user can select an existing volume or create a new one, but
can't progress beyond that point. I have a hack (attached, based against 1.5.1)
to workaround the problem in virt-manager. Commit 582c1d3d fixed virt-install to
copy auth data from the pool to the device config in domXML and as a first step
I'm trying to do the same with virt-manager.
