<br></div>In a nutshell, start with the Ubuntu Amazon EC2 images (not the regular server ISO image), then create and use an additional init ISO image so it would allow password login, then once you login you can add your ssh key.<br>

</div></div>From memory, QEMU simply adds its tap interface to existing bridge. I<br>
had to setup bridge and add wlan0 (my wireless connection) to it. Then,<br>
the virtual machine got its IP from the wireless router.<br>
