Looks pretty dangerous to me. So I'm not sure. There are various MSRs that are detected via CPU family/model (which we pass through) which would then #GP on access. Also this doesn't change the AMD default. Overall, what we have now does seem to work so I'm reluctant to mess with it. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
