Obviously it isn't well known, but I've been using qemu,
and later kvm for testing the Linux-VServer kernels since
ages and naturally, those testing happens on a host also
running a Linux-VServer kernel :)

So yes, it works exceptionally well and it really simple
to handle and control (both, Linux-VServer and kvm).
I haven't had any problems or issues with the setup for
a long time and there is nothing special you have to
consider.

No need for that, usually a tun interface on a bridge
will give you full flexibility, but of course, you can
also use a dedicated nic or whatever else you prefer.
