VirtualBox stopped working with the update to 10.8.2

I just upgraded to 10.8.2 and VitualBox stopped working.


This is the error:

Failed to open a session for the virtual machine dev_env_oraxe.

VT-x is being used by another hypervisor. (VERR_VMX_IN_VMX_ROOT_MODE).

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 {db7ab4ca-2a3f-4183-9243-c1208da92392}


Does anyone have a clue?


I don't want to be forced to restore from backup.


Thanks

MacBook Pro with Retina display, OS X Mountain Lion (10.8.2)

I am also having this problem as are hundreds of others. It affects Retina Macbook Pro's only after upgrading to 10.8.2. Oracle says it's a bug with 10.8.2 that they reported well before the update was Gold Master. Worried that this is not high on Apple's radar -- it should be.
