“VT-x is not available” when i start my Virtual ma

问题:

I have created a virtual machine using the VMWare software and getting an error while starting the Virtual Machine. It says "VT-x is not available:

00:00:03.916 NAT: zone(nm:mbuf_cluster, used:0)

Any idea why I am getting this error?

回答1:

You might try reducing your base memory under settings to around 3175MB and reduce your cores to 1. That should work given that your BIOS is set for virtualization. Use the f12 key, security, virtualization to make sure that it is enabled. If it doesn't say VT-x that is ok, it should say VT-d or the like.

回答2:

VT-x can normally be disabled/enabled in your BIOS.

When your PC is just starting up you should press DEL (or something) to get to the BIOS settings. There you'll find an option to enable VT-technology (or something).

Are you sure your processor supports Intel Virtualization (VT-x) or AMD Virtualization (AMD-V)?

Here you can find Hardware-Assisted Virtualization Detection Tool ( http://www.microsoft.com/downloads/en/details.aspx?FamilyID=0ee2a17f-8538-4619-8d1c-05d27e11adb2&displaylang=en) which will tell you if your hardware supports VT-x.

Alternatively you can find your processor here: http://ark.intel.com/Default.aspx. All AMD processors since 2006 supports Virtualization.
