 Most people install {pve} directly on a local disk. The {pve}

-current default setup uses LVM and 'ext4' for the root

+installation CD offers several options for local disk management, and
+the current default setup uses LVM. The installer let you select a
+single disk for such setup, and uses that disk as physical volume for
+the **V**olume **G**roup (VG) 'pve'. The following output is from a
+test installation using a small 8GB disk:
