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.
