I was unable to install the following OSs: Windows Vista x64, Windows XP x64, Centos 5.2 x64. All report a 32 bit CPU.

Is VT-x/AMD-V enabled CPU required to run a 64 bit OS? (vmware can run a 64 bit OS).

Yes as written in the manual. Unless you attach your VBox.log, there's nothing meaningful we can say.

You *must* enable AMD-V in your BIOS.

VBox.log

Replying to sandervl73:

Yes as written in the manual.

Yes, I found-it after I sent the email.

Is attached.

You *must* enable AMD-V in your BIOS.

I do not have such an option in BIOS. Is an old cpu (4-5 years old or more) and does not have hardware virtualization.

Sorry, but then you're out of luck unfortunately.
