| Yes, it might make sense to document that libvirt can't currently create
| lvm partitions automatically (but such support might be added in the
| future, if parted is enhanced, or if libvirt is taught to use lvm tools
| to do it).

| 
| This particular enum value is used when reading a disk that was
| partitioned externally by some other tool, and already had an lvm
| partition on it (just because libvirt can't create it does not make it
| any less useful for libvirt to report that it exists).
