"VT-x is unavailable" when I start my virtual machine

Question

I created a virtual machine using VMWare software and received an error message when starting the virtual machine. It says: "VT-x is not available:

00:00:03.916 NAT: zone(nm:mbuf_cluster, used:0) 00:00:03.916 NAT: zone(nm:mbuf_packet, used:0) 00:00:03.916 NAT: zone(nm:mbuf_jumbo_pagesize, used:0) 00:00:03.916 NAT: zone(nm:mbuf_jumbo_9k, used:0) 00:00:03.916 NAT: zone(nm:mbuf_jumbo_16k, used:0) 00:00:03.930 VMSetError: D:\tinderbox\win-4.0\src\VBox\VMM\VMMR3\VM.cpp(350) VMR3Create; rc=VERR_VMX_NO_VMX 00:00:03.930 VMSetError: Unknown error creating VM 00:00:03.931 ERROR [COM]: aRC=E_FAIL (0x80004005) aIID={515e8e8d-f932-4d8e-9f32-79a52aead882} aComponent={Console} aText={VT-x is not available.

Any idea why I am getting this error?

Answer 1

You can try to reduce the base memory at settings to about 3175 MB and reduce the number of cores to 1. This should work, considering that your BIOS is set for virtualization. Use the f12 key, security, virtualization to make sure it is turned on. If he does not tell VT-x that this is normal, he should say VT-d or the like.

Answer 2

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

When your computer just starts, you must press DEL (or something else) to go to the BIOS settings. There you will find the option to enable VT technology (or something else).

Answer 3

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

Here you will find a virtualization hardware detection tool ( http://www.microsoft.com/downloads/en/details.aspx?FamilyID=0ee2a17f-8538-4619-8d1c-05d27e11adb2&displaylang=en ) that tells you if your hardware supports VT-x.

Alternatively, you can find your processor here: http://ark.intel.com/Default.aspx . All AMD processors have supported virtualization technology since 2006.
