Nope, still slow... I somehow missed that svm_set_msr() calls svm_set_guest_pat() as well, it does seem to properly change g_pat. The only thing that catches my eyes is that later on all WT entries in g_pat are replaced by WC (0x0007040600070406 -> 0x0007010600070106), but that doesn't seem to make a difference.

If it wasn't for some frustrating and badly timed libvirt update breaking my old VM config some days ago I would have noticed that earlier :/
