[OmniOS-discuss] qemu: too many IDE bus

[Nahum Shalman]

On my SmartOS box I have a one-line script I use for verifying that my USB
stick is still bootable after I update the platform image on it.
It contains:

qemu-system-x86_64 -m 4096 -smp 4 -hda /dev/dsk/c0t0d0p0 -serial stdio

So you should be able to do that with any raw hard drive you might want to
pass through to a virtual machine. (Though I would recommend doing it with
the fancier "-drive" syntax and passing it through with a non-ide
controller.)
