My virtual box is not working since I have upgraded my lion OS.
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).
So I found a forum thread here : https://www.virtualbox.org/ticket/10965, and the solution seems to install again the virtual box again. So now, how can I migrate all the content of my ubuntu I used to ran in the VB ?
