Windows 2008 R2 64 bit V2V conversion fails with “Unable to determine Guest Operating System” error

Windows 2008 R2 64 bit V2V conversion fails with the below error:

 

 

 

 

 

 

 

 

 

The V2V was across the VC with both the source and destination (vCenter and ESXi) being on 4.0 U2 and VMware convertor running on 4.0.1 Build -161434

Resolution: Just change the guest OS type (Right Click the VM> Edit Settings> Options tab)  to anything below 2008 R2 on the source machine and the V2V should go through fine
