Dumb question, but do you have xfs in the kernel? Have you successfully
mounted a simple filesystem without a realtime subvolume?

cat /proc/filesystems
nodev   sockfs
nodev   shm
nodev   pipefs
nodev   proc
        ext2
        xfs
nodev   devpts
nodev   autofs
nodev   nfs

If you build xfs as a module, try doing a modprobe xfs and see what it 
reports.
