As previous posters pointed out I was a bit delusional obviously cpu
type only limits instruction set & is useful for bianry compatibility
but mothing to do with speed limiting or equalization. 

:you can use
:https://wiki.openstack.org/wiki/InstanceResourceQuota

Thanks I think that has the bits I'm looking for.  Had been reading on
a different document about cpu_shares (which are relative and thus not
what I want), but some how missed "cpu_quota" which may be the right
thing for me

so I was also a bit blind :)

Thanks,
