Error: VT-x is disabled in the BIOS for all CPU modes (VERR_VMX_MSR_ALL_VMX_DISABLED) [duplicate]

Answer 1

Non of the solutions worked for me. Instead, I tried the following:

System -> Acceleration -> Uncheck Enable VT-x/AMD-V

Answer 2

When I opened Settings->System->Motherboard, suggested by the answer above, I realized that the .ova file I had downloaded into VirtualBox had settings that exceeded my old computer's RAM size (as suggested by the warning message at the bottom of the screen). Once I was within the capabilities of my machine, the system started adequately.

Answer 3

First, you should check if virtualization is enabled. You can use the free tool provided by SAS Support: http://support.sas.com/kb/46/250.html If virtualization is not enabled, then you have to enable VT-D function in BIOS (for my Asus Motherboard it was in Advanced-->System Agent Configuration settings). I also had to enable Intel Virtualization Technology in CPU settings. Now everything works seamlessly.

Answer 4

Try going to Settings -> System -> Motherboard on VirtualBox and change the RAM size.

Increase the RAM size and try to start it up again. It worked for me, hope it works for you as well!

Answer 5

You may have virtualization disabled on the host computer. To enable:

• Go to your host computer's BIOS (during reboot, press F12, or Delete, or F2, ... depends on computer).
• Find some options regarding virtualization. E.g. recent Lenovo's have it under Security / Virtualization.
• Enable what's there to enable. E.g. VT-d technology [Enable].

This made it work for me.

Answer 6

changing the ram did not work for me so i found another solution

on virtualbox navigate to Settings -> System -> Processor and then click on (Enable PAE/NX). this solved my problem.
