Shouldn't that be "smt=on"? You should probably look at QSB#43 before doing this in any case. The relevant Xen advisory (273) said that for HVM and PVH guests, leakage can only be prevented entirely by disabling SMT/Hyper-threading. I don't think that advice has changed, despite the provision of patches now incorporated in to Qubes. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
