[Ovirt-devel] [PATCH node] Checks for hardware support for virtualization.

[Darryl L. Pierce]

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.
