libvirt - The virtualization API

libvirt is a toolkit to interact with the virtualization
capabilities of recent versions of Linux (and other OSes).

You can enable other optional (not-autodetected) features
by passing some variables to the script
(VAR=yes|no ./libvirt.SlackBuild):
VIRTGROUP=somegroup (default: users) qemu group used
XEN=yes|no (default: no) Xen support
OPENVZ=yes|no (default: no) OpenVZ support
VMWARE=yes|no (default: no) VMware support
ESX=yes|no (default: no) ESX support
VBOX=yes|no (default: no) VirtualBox support

If you want to start the libvirt daemon at boot, add this
to /etc/rc.d/rc.local

# Start libvirt:
if [ -x /etc/rc.d/rc.libvirt ]; then
  /etc/rc.d/rc.libvirt start
fi

Have a look at the commented part of rc.libvirt for some
gotchas.
