Hi Daniel.
Sorry for the late reply on this.
I'm happy that this feature is currently documented in the wiki pages that I'd referenced above and is on the feature plan for 3.6.
The workaround that was specified does what I need for now.
Proper support in 3.6 will need to consider some other things, such as allowing attaching of disks to the sata interface on the q35 machine.
3.5s current workflow doesn't provide a way to cater for that.  Perhaps allowing atachign 'virtio-scsi disks to this interface woudl work fine, but then there's issue with the naming.
Additionally, there have been issues reported with live migration of machines that have the ICH9-AHCI controller enabled.
Any RFE should handle these multifaceted issues - and others I'm not aware of - so given I don't understand all the ins and outs I'd prefer not to raise this.
I'd be interested to hear Sandro's take on how this should likely proceed though.
