Now I'm completely confused. The two mentioned patches, just like most of the larger series from Zachary Amsden, are for _host_ kernel, right? The two backports: arch/x86/kvm/svm.c | 2 +- kvm/arch/x86/kvm/svm.c | 2 +- that's for _host_, not guest... For some reason I tried several patches like the two here for _guest_, not for host. No doubt there were no difference in the results. For host, things are quite different. While 2.6.32 is still very important there, it's not _that_ important as for guest. As far as I can see, most of these can be dealt with by re-loading kvm modules. Let me try these and some of the earlier patches... Oh well... Confusion, confusion, confusion.... :) /mjt
