We address this problem by introducing a new network backend: -net bridge.  This
backend is less flexible than -net tap because it relies on a helper with
elevated privileges to do the heavy lifting of allocating and attaching a tap
device to a bridge.  We use a special purpose helper because we don't want
to elevate the privileges of more generic tools like brctl.

From a user perspective, to use bridged networking with a guest, you simply use:

  qemu -hda linux.img -net bridge -net nic

I know that this patch is less than a day old and untested, but would it
be reasonable to make this the "default" network configuration at some
point in the future?  This certainly seems to be what I want 99% of the
time when I launch qemu or kvm by hand from the command line.

I'd rather make the "default" network configurable via a global configuration file. That way, if a distribution knew that it had a bridge setup for its users, it could make -net bridge the default.
