Virtualization in Linux


Abstract
Three main virtualization approaches—emulation, paravirtualization,
and operating system-level virtualization—are covered, followed
by the implementation examples, comparison of the technologies and
their applications. OS-level virtualization is described in detail, with
examples from OpenVZ. The main kernel components (isolation and
virtualization, resource management, checkpointing and live migration)
and user-level tools are also explained. Typical usage scenarios
of virtualization solutions are presented.
