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)
I think that lists a pretty good subset; would add one more in that:
expand the storage in an existing LV. For non-libvirt uses, what people
really want here is
lvextend -L +20G /dev/vg00/music && ext2online /data/music/
To make that automatable, you'd also need functionality similar to
lvdisplay, i.e. a way to query how big an lv is currently.
But those things together would go a very long way towards more
manageable storage.
