Right. I ran into the same issue last week when I got some hardware
where the VT extensions were disabled. However the reported error from
the NC (hvm not supported) doesn't *always* mean that the BIOS has
disabled VT extensions.

I've run into this issue on some configuration that had already been
running a UEC infrastructure before. Upon reboot the NC would fail with
the same error message - this is the situation I described in my first
comment.

Sounds like a good option.
