Xen have feature of having device model in separate domain (called stub
domain). It used to be enabled by special 'stubdom-dm' device model
path. Recent xl have separate config option for this feature
(device_model_stubdomain_override), but I'm not sure if it worth
introducing another xen-specific option in general domain XML syntax.
Also use os->cmdline as extra arguments for qemu (for HVM only). This
use of os->cmdline is rather dirty hack, but I haven't idea what better
attribute use for it. Perhaps worth new attribute (in <emulator/>
element?). Anyway os->cmdline was unused for HVM domains.
