Hey,
So, here are the patches needed to complete the QEMU NIC hotplug
work by supporting network and bridge backed interfaces.
We support this by passing a tap file descriptor to qemu over
the monitor socket using SCM_RIGHTS.
The monitor commands required for this (getfd and closefd) are
queued up in Anthony's queue and should be in qemu-0.11-rc1 which is due
to be released very soon:

Note: I just remembered I'm not handling missing support for
these commands very well. I'll make it handle an 'unknown command' reply
gracefully by failing the attach tommorrow.
Cheers,
Mark.
