If replace with new version (or RC2 version) then does not work. if use harddisk.img raw file instead of USB physical device then I get BIOS POST messages and it boots to image OK. So appears to be USB or physicaldisk support issue??? To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/825776/+subscriptions
