Virtual Box 32 bit

Linux Maniac · 11-01-2017, 01:34 PM

Hi,
I am in need of desperate help. I have installed my virtual box and trying to set up a machine. For some strange reason, I don't have any options with 64 bit. All of them are 32 bits. Can anyone guide me on how to get a Red Hat 64 bit?
Thanks in advance.

Is your host OS 64-bit?
Did you install the 64-bit version of VirtualBox?:

Thanks in advance.

What did you instal VB ON? What hardware, what OS, what bitwidth, and where did you get it to install? Can you provide the package name?

A lot of intel processors don't allow 64bit guests.

Assuming that you have 64-bit host enable virtualisation in your host BIOS, that is intel Virtualisation Technology and VT-d must be both enabled in the BIOS

you may need to run virtualbox repair

hope this will help

If you are using an older microprocessor, it might not have hardware support for what you are trying to do ... and VirtualBox would know this.

(You need to remove the Hyper-V feature from Windows if you want to use 64bit in VBox.
Hyper-V takes over VT-x completely which is needed for 64bit guests in Virtualbox.)

Or are you trying to do 'nested virtualization'?
"VirtualBox does not pass VT-X/AMD-V to the guest operating system"

The HOST MUST be all 64 bit for a guest to run 64bit.
64 bit software will support 32bit execution but definitely not the other way round.
