[libvirt] [PATCH 1/1] [RFC] Parallels Server Bare Metal driver stub

Dmitry Mishin dim at parallels.com
Mon Sep 26 11:59:05 UTC 2011


Parallels Server Bare Metal is a virtualization solution which allows to run
both Containers (OpenVZ-like) and virtual machines (like any other hardware
hypervisor).

This patch implements initial driver stub with almost no functionality except an
ability to open and close driver. At the same time it contains initialization of
Parallels API and clearly demonstrates supposed approach to future driver
implementation. In particular, I suppose to use parallels-virtualization-sdk
library provisioned with the PSBM distribution (and separately also) for PSBM's
virtual servers management.
