I just noticed that the patch set is missing the initialization of 
guest_default_cfg.size = size (or legacy_size) in the following functions:

   fpu__init_system_xstate_size_legacy()
   fpu__init_disable_system_xstate()

Without that, it looks buggy when XSAVE is either unavailable or disabled.

Thanks,
