NOTE: this patch adds text to the /etc/issue file so that the user
      sees the lack of hardware virt on login.

If hardware support is not found then an error is logged calling out
that hardware virt is not supported.

NOTE: This patch incorporates changes suggested by pmyers. If hardware
      virtualization is not available, the system updates /etc/issue*
      with a message. It then appends to that whether hardware virtual-
      ization is possible with the current hardware.

If hardware support is not found then an error is logged calling out
that hardware virt is not supported.
