Does the <input type='mouse' bus='xen'/> get assigned by default ?
Because, for Xen  PV the values are getting assigned by default even 
though the tc did not supply them .
Ex: check the vsxml output from the tc 41_cs_to_settingdefinestate.py.
The default values are not getting assigned for KVM though.
