Severity: normal
qemu support emulating scsi as the device.
qemubuilder's doc says that scsi can be emulated by using the following
settings:
ARCH_DISKDEVICE=sd
When settings the above, I get the following:

WARNING bootdevice may be renamed. Try root=/dev/hda
Gave up waiting for root device. Common problems:
- Boot args (cat /proc/cmdline)
- Check rootdelay= (did the system wait long enough?)
- Check root= (did the system wait for the right device?)
- Missing modules (cat /proc/modules; ls /dev)
ALERT! /dev/sda does not exist. Dropping to a shell!

/bin/sh: can't access tty; job control turned off
(initramfs)
The log does understand the sd setting and sets the root=/dev/sda
parameter. But it doesn't do the same for qemu command-line.
To emulate scsi, as per the qemu doc, the following is required:
qemu -drive file=file,if=scsi,bus=0,unit=6
Qemu also seems to be supporting virtio. Adding support for that too
would be good.
The current IDE emulation is very resource hungry and keeps hitting
resets.
