Description of problem:

I have clusters with "Intel Nehalem Family" CPU model name.
After adding my hosts to this cluster they change theirs status to non operational due to missing CPU flags . 
After further investigation we found out that a recent patch which disallow cross-vendor virtualization lead to this problem . 




Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1.Add cluster with "Intel Nehalem Family" cpu name . 
2.Add host with Nehalem CPU. 
3.Host become non operational 

  
Actual results:


Expected results:
