11 A container is an isolated system with a separate root file system and
12 operating system userland. The containers share a common operating system
13 kernel.
15 LVM
16 Logical volume manager. The LVM allows to allocate space on block
17 devices more dynamically than with traditional partitions. The block
18 devices are managed as physical volumes (PVs) that are grouped in volume
19 groups (VGs). Space can be allocated as logical volumes (LVs) that can be
20 formatted using regular file system tools. LVs can be resized without
21 reboot. LVM provides snapshot functionality that is useful for backup and
22 upgrade procedures.
