will force use of vhost-net (if it's not available, the domain will fail to start). if driver name="qemu", vhost-net will not be used even if it is available.
Changes from V1:
enum now starts at 0 instead of -1. I just disallow "default" when parsing. This eliminates the need for vhost_specified.
Removed superfluous 3rd arg to open().
Thanks for those fixes.

I probably would have done either this shorthand: (b = virDomain...FromString) <= 0 or, keeping the long form, used a symbolic name rather than a magic number: (b = virDomain...FromString) < 0 || (b == VIR_DOMAIN_NET_BACKEND_TYPE_DEFAULT) But that's just style, so up to you if you want to make a tweak, or keep it as-is.
