VirtualBox states "VT-x is not available (VERR_VMX_NO_VMX)."

I am using VirtualBox v5.2.0r118431 and using an HP EliteBook 840 G3. When I try to launch a CentOS guest I am receiving the error "VT-x is not available (VERR_VMX_NO_VMX)." First thing was to check the BIOS and both VT-x and VT-d are enabled in the BIOS. I did find another SuperUser article here, but after disabling the Hyper-V service(s) then rebooted I still see the same area. The following services are shown as disabled in the Services tab under Computer Management:

I didn't see any other services related to Hyper-V enabled. Any thoughts what I can determine is causing the resource conflicts? Perhaps an anti-virus?

Thanks and regrads

 

VT-x is not available, but is enabled in BIOS

There are three common culprits for the type of error the user is seeing:

• VT-x is not enabled in the BIOS
  
• The CPU doesn't support VT-x
  
• Hyper-V virtualization is enabled in Windows

Afterwards, reboot the PC and try VirtualBox again.

 

VT x is not available in BIOS

Hi,

I am working on Intel Pentium Dual Core T4500, having windows 10 OS. I am trying to run a Windows 7 virtual machine using VMware workstation player 12 but it shows Intel VT-x is disabled in BIOS, but in BIOS I don't see this option
at all. I have searched on intel site that this particular model T4500 doesn't support VT-x. Is there any turn around. If I use Virtualbox will that solve my problem.

Please suggest.

Thanks.
