I'm trying to use the latest version of VirtualBox and it's giving me this error:

Failed to open a session for the virtual machine ---.

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

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


Anyone know what's up? I have the Android SDK installed, could that be an issue? Was able to run VirtualBox in previous versions of Lion before...


Thanks.

The problem is definitely QEMU. I don't have the details all sorted out yet but it looks to me as if this has something to do with the video acceleration package that comes with the new Intel emulator.
