As mentioned before we do a PV port of a (not open source) mainframe os to xen and this os is using protection keys. So protection key support in xen is necessary. A short discussion to the protection key support was on the list: http://lists.xensource.com/archives/html/xen-ia64-devel/2007-04/msg00129.html I did a first implementation for PV guests with 1 pkr reserved for the hypervisor. I'll send a RFC and a first patch within the next days. Thanks.
