VirtualBox Import Appliance; VT-x is not available

May 27, 2012

When importing a virtual appliance from a VT-x machine into a non VT-x one, you may end up with this error:

VT-x is not available: verr_vmx_no_vmx

Well the key to fix this is to disable VT-x (i.e. hardware virtualization instructions) but the problem is that the new host machine’s virtualbox settings window is all disabled:

So how can I disable VT-x then? Then solution I found it to open the appliance vbox XML file and manually disable HardwareVirtualEx.

vim ~/VirtualBox\ VMs/windows/windows.vbox

Then search for HardwareVirtEx and set all enabled items to false.

    Humm… it gives an error saying that requires x86-64 CPU and it found a i686 CPU.
    It’s a 64-bit, running Windows Server 2008 R2 Standard, with 16 GB RAM. Any reasons why?
