I have Ubuntu 12.04 installed on my machine. I also installed Virtualbox so that I can run windows 7.

I set my virtual box with 4 GB RAM and 25 GB virtual HDD and after I press Start, it doesnt boot from the windows dvd in the optical drive, but instead i get this error:

Failed to open a session for the virtual machine win7.

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}

Do you have any idea what is it and how I could overcome this?

Thank you!
