Please note that the newest Dell BIOS (A14) for this laptop will support a hardware virtualization CPU in the same socket as is now holding Intel T4300 CPU but the CPU installed does not support this. Therefore the required option to turn on/off hardware virtualization is not available in the BIOS presented to me. The virtualbox startup file has all hardware virtualization turned off.

Verified proof that VirtualBox fails to recognise CPU is without VT-x

sudo kvm-ok 63 INFO: Your CPU does not support KVM extensions 64 KVM acceleration can NOT be used
virt-host-validate 135 QEMU: Checking for hardware virtualization : FAIL (Only emulated CPUs are available, performance will be significantly limited)
I posted this complaint on two other bug postings as a "me too" report but the moderator closed and locked those postings. That moderator said I needed to enable VT-x because VirtualBox 6.1.18 requires it whereas VirtualBox 5.x was compiled a different way and did not require it. What is missing is a clear statement that the "requirement" of VT-x makes obsolete all non-VT-x computers by design of Oracle. If so, clearly say so.
I opened this as a new bug report and have not seen any requests for more information.

Found this obscure note.... "Drop recompiler" So moderator is correct but did not help me understand why. I am updating the CPU (extremely worried about this) to DELL vendor version with VT-x but not Hypervisor. If this will not work...... TELL ME!
"VirtualBox 6.1.0 (released December 10 2019)
This is a major update. The following major new features were added:
Implemented support for ...
In addition, the following items were fixed and/or added:
Virtualization core: Drop recompiler, i.e. running VMs now needs a CPU supporting hardware virtualization"
Forgot to say the guest O/S is 32 bit WinXP that worked quite well with VirtualBox 5.x, Kubuntu 18.04, and Dell BIOS A9 (If I remember the BIOS number right) on this same machine.
