10992,Systematic error VERR_VMX_IN_VMX_ROOT_MODE when starting VirtualBox,tom_WR,,"Host is Windows 7 64 bits running on a Core i5 laptop
Guest is Fedora 14 64 bits

I have a systematic fail when launching the VM. Disabled VMware services running in parallel, but no change. Note that I entered the ticket for 4.2.0, but this is also true for the 4.1.x versions.

The image I'm using works fine on other hosts (Linux principally)

Error message abstract (will enter full logs in the ticket):

Failed to open a session for the virtual machine Fedora14-x64-KP.

VirtualBox can't operate in VMX root mode. Please close all other virtualization programs. (VERR_VMX_IN_VMX_ROOT_MODE).

Result Code: E_FAIL (0x80004005)
Component: Console
Interface: IConsole {1968b7d3-e3bf-4ceb-99e0-cb7c913317bb}
