[Xen-devel] Benchmark in the VM



Hi,
   When I run some workloads from SPECCPU2006. I found that the retired instruction number vary significantly between VM and PM according to xenoprof. For example:

   Workload                                            Insts                                            Platform
   435.gromacs (CPU intensive)                4458151                                       PM
   435.gromacs                                       151265683                                   VM
   450.soplex   (Memory intensive)            760142                                        PM
    450.soplex                                          23311208                                    VM

What is the reason? Does Xen use interpret? Thank you!
