Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.

Laine Stump 3f9274a524 conf: add <vlan> element to network and domain interface elements 
The following config elements now support a <vlan> subelements:

within a domain: <interface>, and the <actual> subelement of <interface>
within a network: the toplevel, as well as any <portgroup>

Each vlan element must have one or more <tag id='n'/> subelements.  If
there is more than one tag, it is assumed that vlan trunking is being
requested. If trunking is required with only a single tag, the
attribute "trunk='yes'" should be added to the toplevel <vlan>
element.

Some examples:

  <interface type='hostdev'/>
    <vlan>
      <tag id='42'/>
    </vlan>
    <mac address='52:54:00:12:34:56'/>
    ...
  </interface>

  <network>
    <name>vlan-net</name>
    <vlan trunk='yes'>
      <tag id='30'/>
    </vlan>
    <virtualport type='openvswitch'/>
  </network>

  <interface type='network'/>
    <source network='vlan-net'/>
    ...
  </interface>

  <network>
    <name>trunk-vlan</name>
    <vlan>
      <tag id='42'/>
      <tag id='43'/>
    </vlan>
    ...
  </network>

  <network>
    <name>multi</name>
    ...
    <portgroup name='production'/>
      <vlan>
        <tag id='42'/>
      </vlan>
    </portgroup>
    <portgroup name='test'/>
      <vlan>
        <tag id='666'/>
      </vlan>
    </portgroup>
  </network>

  <interface type='network'/>
    <source network='multi' portgroup='test'/>
    ...
  </interface>

IMPORTANT NOTE: As of this patch there is no backend support for the
vlan element for *any* network device type. When support is added in
later patches, it will only be for those select network types that
support setting up a vlan on the host side, without the guest's
involvement. (For example, it will be possible to configure a vlan for
a guest connected to an openvswitch bridge, but it won't be possible
to do that for one that is connected to a standard Linux host bridge.)

         LibVirt : simple API for virtualization

  Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
