qemu port redirection

The redir flag has been deprecated. Syntax for e.g. ssh redirection is now -netdev user,id=ether0,hostfwd=tcp:127.0.0.1:2222-:22 -device rtl8139,netdev=ether0

Notice that

  • the syntax has changed (- in redirection)
  • you need to give an id
  • you need to define the virtual device and use the id
(you'll probably also want -usbdevice tablet to avoid mouse grab issues now)
