after installing a 14core Xeon VirtualBox does not let me choose 64 bit on anything

[BirdDad]

I don't know what is going on but VB does not like my new processor.
It refuses to allow me to install 64 OSes and will not let me run my exisiting ones.
Anyone have an idea of what is going on?
Thanks

VMWare either!

You probably have to enable virtualization extensions in the bios.

Well, you buy an ES, you take your chances with it actually working the way a retail chip would.

if virtualization was not enabled then I wouldn't be able to do 32 bit either
I am going to return the chip

Actually, you can run virtualization software on computers that don't have any virtualization hardware built-in; it simply limits the guest OS to 32-bits. You can also install 64-bit guests on 32-bit hosts (if you do have hardware virtualization).

However, here are 3 things to check:

1. Is your Host OS 64-bit?

2.. Make sure Intel Virtualization Technology is enabled in the BIOS. Depending on the chip, it can be called Intel Virtualization Technology, Vanderpool VT-x, VT-d, etc. Also note that there can be more than one setting to toggle on (for example, you may need to enable both Intel Virtualization Technology AND VT-x in BIOS). Otherwise, the virtualization software may be running in 32-bit software emulation mode rather than 64-bit hardware virtualization mode.

3. If you're running a server OS, uninstall Hyper-V (uncheck to remove & reboot).

Some questions for you:

1. What CPU model is it?

2. What motherboard is it? (and BIOS revision)

3. What Host OS are you using? Is it 32 or 64-bit?

Absolutely false, as Kaido points out.

Are you reading any of the replies you got? Have you tried to enable virtualization instructions in your BIOS as dave_the_nerd suggested?

Virt was turned off-it must have happened when I switched processors, probably loaded defaults or something.
