Given the rarity of your machine I'm currently leaning towards _not_
reverting the change.  I'll check another non-Xeon Core 2 tomorrow that
is from December 2008 (IIRC).  If that one also lacks vNMI, or if I get
other reports, I suppose I will have to reconsider that.


afraid I've the same issue with 4.12, kvm_intel doesn't load and won't (but does on 4.11) on my Dell XPS M1210 with a Core 2 Duo T7200 from April 2007.

cpuinfo and vmxcap output attached

Thanks,
