I should add, in a libvirt context it's probably going to be useful to also:

* list available volume groups (vgscan)
* list space available in each VG (vgdisplay name-of-vg)
* show how VGs relate to PGs (pvscan)

The LVM tools use quite a sophisticated internal API which isn't 
exported - but see for example tools/tools.h and include/*.h in the LVM2 
source code.  <libdevmapper.h> is also available, but much more lowlevel.
