Did you probably forget to specify the prefix to install it into?  you
can do "which libvirtd" to see that you probably installed it into
/usr/local/sbin.  Specifying the prefix should help.

Getting to your "to get VT-d working", you should check whether
everything is enabled in BIOS.  That's usually the case if it's not
working for you.

Please wrap long lines,
Martin
