:pve-toplevel:
endif::manvolnum[]

The following sections will focus on common virtualization tasks and explain the
{pve} specifics regarding the administration and management of the host machine.

{pve} is based on https://www.debian.org/[Debian GNU/Linux] with additional
repositories to provide the {pve} related packages. This means that the full
range of Debian packages is available including security updates and bug fixes.
{pve} provides it's own Linux kernel based on the Ubuntu kernel. It has all the
necessary virtualization and container features enabled and includes
https://zfsonlinux.org[ZFS] and several extra hardware drivers.

For other topics not included in the following sections, please refer to the
Debian documentation. The
https://debian-handbook.info/download/stable/debian-handbook.pdf[Debian
Administrator\'s Handbook] is available online, and provides a comprehensive
introduction to the Debian operating system (see xref:Hertzog13[]).
