vt-x

I have installed the latest version of virtualbox onto my Hewlett Pakard (h8-1170uk) I have a intel i7 2600 cpu and 8 gb of ram

I can get virtual box to create several sessions of different operating systems at the same time, but whenever i try to get 1 session to open up using more than 1 processor option select ( i wanted one of my session access to 2 processors ) i keep getting this error message

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

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

I have search many times and cannot find a option to correct this. I have check my BIOS and there are no options about VT-x or Virtualisation or anything.

Am i doing something wrong ? Why does Virtualbox run fine when just using the 1 processor option ?
