Correct. > I tried sevral platforms, if I used no EPT suported machine, everything is OK as yours; if I used EPT supported machine, and then disable EPT with "modprobe kvm_intel ept=0", then issue happen. That's what I thought - probably vpid+shadow interaction. I'll test it out. I usually test on an old machine since shadow is much more stressful than ept. But shadow+vpid is even more stressful, I'll move my testing there. -- error compiling committee.c: too many arguments to function
