I completely agree with you about that, and my first implementation and tests was pretty close to your suggestion, but I have some important points to explain: 1) Power systems don't have sound supporyt, so the usage of <sound model='%(sound_model)s' /> directly in XML will not work. If you look better to the diff in template_specs on osinfo.py, you can see that only the dictionaries for x86_64 have the sound_model set up as parameter. 2) During my tests on x86_64, the usage of keyboard (kbd) line didn't work on guests - the keyboard didn't work. I did all test on Fedora 19 and RHEL6.5 as hosts, creating Fedora 20 and Debian 7 guests (via VNC and Spice). However, Power systems need this line to enable keyboard in the guests. So, in the end of this story, for Power systems we need in XML: <input type='mouse' bus='usb'/> <input type='kbd' bus='usb'> </input> , and for x86_64: <sound model='ich6' /> <input type='mouse' bus='ps2'/> Once the set of parameters expected are different between Power and x86_64, the best solution I found was create a method to check the template.info() parameters and fill only that necessary to each architecture. I still maintain my implementation suggestion as fix to solve the template differences between these architectures.
