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

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.

(not tested, but might work in bash)

qemu -other-options -tun-fd 3 3<>/dev/net/tun
