I posted this earlier in the wrong thread, I tried to use the
qemu_disable_patches.diff today with 3.3.1 rc4 but it didn't hide the
devices or change cdrom to emulated when using the pre11 drivers, this
is what I did:

hg clone -r 3.3.1-rc4 http://xenbits.xensource.com/xen-3.3-testing.hg
cd xen-3.3-testing.hg
make tools # I believe this is necessary to pull ioemu-remote ?
cd tools/ioemu-remote
patch -p1 -i /usr/src/qemu-pci-disable.patch # I removed the last
chunk of the patch which changes vl.c as the changes are in 3.3.1-rc4.
make clean
cd ../../
make clean
make tools
make install-tools
/etc/init.d/xend restart

I did not recompile xen, only the tools.

In my vista hvm the Intel IDE and Realtek NIC are still visible, and
cdrom is XEN PV not ioemu/qemu.

Is my method incorrect?
