Vt-x/AMD-V hardware acceleration is not available on your system

Question

I imported a VM from Oracle and tried to open it. When I try to run the VM, i get the following message:

VT-x/AMD-V hardware acceleration is not available on your system. Your 64-bit guest will fail to detect a 64-bit CPU and will not be able to boot.

As it can be seen from configuration, the VT-x is available on my machine:

Can someone tell me what else should I do in order to be able to start he VM, please?

Thank you,

Have you tried turning on VT-x on your motherboard/BIOS/UEFI? — Aron, Aug 02 '17 at 17:06
the marked value from attached screenshot doesn't mean that the VT-x is active? — mikcutu, Aug 04 '17 at 09:29

You need to Enable Virtual Hardware in BIOS.

Press F2 key at startup BIOS Setup.
Switch to the Advanced Mode tab then choose CPU Configuration option.
Scroll down to the "Intel Virtualization Technology" value, and then change [Disabled]->[Enabled].
Save Changes and Exit.

It depends on what tool your using to run your VM,

e.g. Virtual box there is setting to enable Hardware virtualization for guest VM

Edited:

If you don't have hardware Virtualisation enable you can try with software Virtualisation this will impact performance

The acceleration tab from system option is grayed. I cannot access it. – mikcutu Aug 04 '17 at 09:32
Have you enabled it in Bios settings ? – Vikrant Pawar Aug 08 '17 at 05:35

Unfortunately, I am not able to perform modifications in BIOS as it is password protected but I was able to see that the Hardware Virtualization option is on "Disabled". – mikcutu Aug 10 '17 at 12:43

This is how I resolved this problem:

I restarted computer, disabled virtualization from BIOS, and started computer.
When I opened Virtualbox, nothing changed (the same error).
I restarted computer again, and enabled virtualization from BIOS, and started computer.
When I opened Virtualbox, guest OS started without problem.
