Based on this Performance comparision on VMware Workstation 6.5 (it is in german) , Nehalem is the 3 generation of Virtualization plattform
Vmware has although described this in the vmware world 2007 document
TA68: Performance Aspects of x86 Virtualization
For performance result in vmware I look only at vmmark and intel vcondolidate benchmark.
VMware VMMARK Results
The benchmark above by zdnet is about the Virtualization Features AMD-V versus Intel EPT.
AMD RVI Benchmark
Conclusion: AMD RVI helps most for 64 Bit Applications. 32 Bit ?
Also a good Articel about VMwark Results and a good conclusion of old xeon
"It is clear that the Xeon 7350 is at the end of
its life: it offers a little more than 2/3 of the performance of the
best Opteron while using a lot more power."
*The second generation: Intel's
EPT and AMD's NPT*
Look at the figure "The enter VMM and exit VMM latency has been lowered over time with the different Xeon families."
Waiting for Vmwark Results of Nehalem with out. If you look at the second Linpack core i7 benchmark without HT, i want to see vmware nehelem benchmark.
