To start a guest, I have this in the guest config:
disk = [ 'phy:/dev/mapper/vg-guest_q35,sda,w' ]
machine='q35'

If you wish, you can recompile only hvmloader and qemu and have
something like this in your guest config:
firmware_override      = '/root/hvmloader-q35'
device_model_override = '/root/qemu-xen-q35'
device_model_version = 'qemu-xen'
device_model_args_hvm = [ '-machine', 'q35,accel=xen' ]


Hope that help.
