virtualbox.org

Today I have updated from version 4.2.16 r86992 to 4.3.6 r91406.
I also installed the extension pack 4.3.6.The entire installation was uneventful.

My SO: Windows Server 2003 Enterprise x64 SP2

My server has 4 CPUs but the new version 4.3.6 only show 2. And display a warning message:

are assigned to the VM more virtual CPUs than the number of physical host CPUs.

This message is contradictory.

Is there any solution? or How to return to the previous version of VirtualBox?.

Thanks
