Test this scenario by disabling Microsoft Hyper V. There are several ways to disable Hyper-V virtualization. However, let us try to make it as easy as possible. To disable Microsoft Hyper V from the command line with advanced privileges:

  • Click on Windows Key + R to open the Run dialog box. Then type “cmd” and press Ctrl + Shift + Enter to open a command line with elevated privileges. Click Yes when prompted in the User Account Control (UAC) window.
  • On the command line with elevated privileges, insert the following command to disable Microsoft Hyper V and press Enter:
  • DISM.exe / Online / Disable the function: Microsoft Hyper-V
  • Press ENTER key
  • Disable bcdedit / hypervisorlaunchtype
  • Press ENTER key
  • If the command is successful, close the command line with elevated privileges and reboot the computer.
  • On the next boot, open the Virtualbox machine again and see if you get the same error message.

To fix the error verr_vmx_no vmx vt x, you can also disable the main Windows Protector isolation.

  • Simultaneously press the Windows and I keys to open the settings.
  • Select “Update and Security” from the pop-up window to continue.
  • Then select Open Windows Security to continue.
  • In the right pane, select Device Security to continue.
  • From the pop-up window, click Kernel Insulation Information.
  • Then set the switch under “Memory Integrity” to “Off”.

Then reboot your computer and check to see if it fixes the error that vt-x is not available.

Enable VT-X in the BIOS settings

Disable USB ports in BIOS

If virtualization technology is disabled in the BIOS settings, you may also see an error message that vt-x is not available (verr_vmx_no_vmx). So you can enable vt-x in the BIOS settings.

  • Start your computer. When the Windows logo appears, constantly press the “Setup” button to enter the BIOS.
  • After entering the BIOS, go to the “Security” tab and scroll down to “System Security”.
  • Then check to see if virtualization or VTx / VTd technology is specified here and if it is enabled.
  • Otherwise, change the status to on.

After all the steps, reboot your computer to see if the error that vt-x is unavailable (verr_vmx_no_vmx) is corrected.
