Yes, I agree. But if a user specifies <emulator>/bla/bla</emulator>,
how should libvirt populate device_model_version? Is it expected that
qemu-xen-traditional will always be the 0.10.2 version? If so, libxl
could DTRT by setting device_model_version to qemu-xen-traditional when
detecting the the requested emulator version in 0.10.2.
qemu-xen-traditional certainly won't be getting any version bumps
(certainly not for the first two numbers, I suppose there is a
vanishingly small chance for the third one), so if that is the version
it reports then that might work.
