This one looks better, your system will thank (more cache, fsb speed yet
still the same low TDP) :-)

Sure, your BIOS has to provide an option to toggle "on" VT-x, if no, ask the
manufacturer for a BIOS update or how to enable this.
And as you seem to be running a 64-bits host OS there shouldn't be more
tweaks to do.

I think the warning is harmless. I also get it from another native applications
(e.g., ntpd) and IIRC, the message came from a library (libpcap) but is pointless.
