If you could start qemu with both ata and ahci, add a new lun to the ahci
controller, and use beadm to migrate to the achi disk, then disconnect the
ata disk/controller and bump the cores back to 4.

I think that workaround 1 is not technically correct.  however, you'd need
a really good understanding of Solaris/opensolaris/OI to force the system
to reenumerate the device path from a failsafe boot.  But this is not for
the faint of heart.

If it's a new install (ie, not much customization/data), why not just start
a new QEMU instance that uses the ahci controller?
