+ <braunr> tschwinge: about your concern with regard to performance
+ measurements, you could run kvm with hugetlbfs and cpuset
+ <braunr> on a machine that provides nested page tables, this makes the
+ virtualization overhead as small as it could be considering the
+ implementatoin
+ <braunr> hugetlbs reduces the overhead of page faults, and also implies
+ locked memory while cpuset isolates the vm from global scheduling
+ <braunr> hugetlbfs*
+ <tschwinge> Thanks, will look into that.
