[libvirt] [PATCHv2 3/3] qemu: command: Handle RBD storage pools

[Adam Walters]

This patch modifies the switch statement in qemuBuildVolumeString
to format and pass the needed argument to handle a volume from an
RBD storage pool properly. If the volume is a VIR_STORAGE_VOL_NETWORK
but is not from an RBD pool, I goto cleanup, just like the other
unimplemented volume types. Currently, the code only supports RBD
volumes, as I lack the facilities to test other network storage pools.
Once I have the ability to test those, I will revisit the possibility
of implementing additional types.
