Thanks Josh! After building and installing libvirt 1.0.0 RPMs I unfortunately
seem to have taken a step backwards. Any use of network disks with
protocol="rbd" causes libvirt to bail with a dreaded 'No such file or
directory':

2012-12-10 20:08:37.203+0000: 16691: error : virFileOpenAs:1077 : failed to open file 'volumes/volume-485390a9-5a39-46c1-8434-872acbc645d8': No such file or directory
2012-12-10 20:08:37.203+0000: 16691: error : virStorageFileGetMetadataRecurse:962 : cannot open file 'volumes/volume-485390a9-5a39-46c1-8434-872acbc645d8': No such file or directory

I see there is a specific flag in the spec file for RBD support in this version
but I'm assuming that's more for pool support, correct? I get the same failures
either way. Is my disk XML now wrong with newer versions? Or perhaps is there a
recommended version of libvirt besides the latest 1.0.0?

I think I'm so close. Attaching volumes is pretty much the last piece of
functionality before I start just hammering this platform for stability. Thanks
again!
