[libvirt] [PATCH] Fix possible segfault if starting qemu vm with an inactive virtual network

[Cole Robinson <crobinso@xxxxxxxxxx>]

The attached patch fixes a possible segfault if trying
to start a domain which tries to use an inactive
virtual network. We should explicitly catch that error
and report it, but that's a separate patch.

Thanks,
Cole
