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 35ca0db359 conf: fix virDomainNetGetActualDirect*() and BridgeName()
This resolves:

   https://bugzilla.redhat.com/show_bug.cgi?id=881480

These three functions:

  virDomainNetGetActualBridgeName
  virDomainNetGetActualDirectDev
  virDomainNetGetActualDirectMode

return attributes that are in a union whose contents are interpreted
differently depending on the actual->type and so they should only
return non-0 when actual->type is 'bridge' (in the first case) or
'direct' (in the other two cases, but I had neglected to do that, so
...DirectDev() was returning bridge.brname (which happens to share the
same spot in the union with direct.linkdev) if actual->type was
'bridge', and ...BridgeName was returning direct.linkdev when
actual->type was 'direct'.

How does this involve Bug 881480 (which was about the inability to
switch between two networks that both have "<forward mode='bridge'/>
<bridge name='xxx'/>"? Whenever the return value of
virDomainNetGetActualDirectDev() for the new and old network
definitions doesn't match, qemuDomainChangeNet() requires a "complete
reconnect" of the device, which qemu currently doesn't
support. ...DirectDev() *should* have been returning NULL for old and
new, but was instead returning the old and new bridge names, which
differ.

(The other two functions weren't causing any behavioral problems in
virDomainChangeNet(), but their problem and fix was identical, so I
included them in this same patch).

         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.
