I've installed Virtualbox on ubuntu 12.04 64 bit , but when I try installing Windows7 64bit I got this error message:

Failed to open a session for the virtual machine Microsoft.

VT-x features locked or unavailable in MSR. (VERR_VMX_MSR_LOCKED_OR_DISABLED).

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

thanks for your help

Try update the kernel. Also check if Your bios do not block virtual file systems (I don't have any more detail about it right now). –  Adobe Jul 30 '12 at 14:17
