I can see this being a necessary workaround, but going over the other errata there are some of quite a bit higher importance to work around (KNL13) or at least check whether we're affected (KNL4, KNL8), if we really care about supporting Xen on this processor model. I'd appreciate other opinions namely from the people on Cc. Jan _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org https://lists.xen.org/xen-devel
