OK I'm losing it. New file system created with:

btrfs-progs-0.20.rc1.20130501git7854c8b-4.fc20.x86_64
3.11.3-301.fc20.x86_64

I still can't move a subvolume into a subvolume. Using identical syntax with a directory as target works OK. 

[root@f20s mnt]# mv subvol1 subvol2
mv: cannot move ‘subvol1’ to ‘subvol2/subvol1’: File exists
