The workaround seems good, but there still tends to be issues bringing up the multipath devices on boot with QEMU in my testing; just the workaround isn't always sufficient: break=pre-multipath then resuming helps out there.
I think this all goes back to multipath-tools updates that would help a whole lot; but they may be a little too intrusive past feature freeze -- I'm looking into just updating the udev rules now.
