It would be nice if qemu could be configured to use an existing

others be interested in such an addition, perhaps "qemu -tun tun0" or
User Mode Linux allows something similar. See the section "TUN/TAP
with a preconfigured tap device" at
I thought it already does, via the -tun-fd option ... though I have not
seen an example of how to use this option / determine the file
descriptor of an existing tun/tap interface, so I dont know how to use
it as well. An example would be good.
