Dears,

I am struggling with Virtualbox to work after clean installation. The below error message pops up and have done what I possibly can do, but without success.

Please help

---error message---

VirtualBox can't operate in VMX root mode. Please disable the KVM kernel extension, recompile your kernel and reboot.
VBox status code: -4011 (VERR_VMX_IN_VMX_ROOT_MODE).


Result Code:
NS_ERROR_FAILURE (0x80004005)
Component:
Console
Interface:
IConsole {e3c6d4a1-a935-47ca-b16d-f9e9c496e53e}

---------------------

P.S.
My laptop (Fujitsu T4210) is dual core and of Intel chipset that support KVM.

Awaiting your prompt response.

Thanks in advance.
