I've used windows images (win 2008/2012) taken from esx with vmware tools
installed and boot disk configured to use pvscsi.
Also I've used linux (ubuntu 12.04) where pvscsi drivers installed by
default and booted it using qemu cmd similar to this:

./x86_64-softmmu/qemu-system-x86_64 -snapshot -device pvscsi,id=pvscsi0
-device scsi-disk,bus=pvscsi0.0,drive=drive0 -drive
id=drive0,if=none,file=ubuntu-12.04.qcow2 -bios roms/seabios/out/bios.bin
