- core i7 @ 1.6GHz gives me eight threads. The RAM is really fast, too,
so the overall system is very responsive. Great power savings stuff.

- Haven't tried kvm but would probably work fine.

- From /proc/cpuinfo:
  address sizes   : 36 bits physical, 48 bits virtual

  That's only 8GB physical, but that's probably a reasonable limit at
the moment.
