I also have lost write access to the wiki, no idea what happened there.
I started the page, but it subsequently became protected.

We never added support for the qemu command line directly, the
plan was to do that using helper scripts.

The only way to do it is to redirect both input and output
to the tap device, so you ned to do

-net nic,model=virtio,netdev=foo -netdev tap,id=foo,fd=3 <>3

when starting from bash.
