isn't this supposed to work?? an i7 does have PAE. a grep on pae in /proc/cpuinfo confirms it. and

and

 kvm-ok
  INFO: /dev/kvm exists
  KVM acceleration can be used

does anyone know what is going on here?

/iaw

I don't know about your PAE CPU being treated like a non-PAGE CPU. However, we had the same error message, This kernel does not support a non-PAE CPU, and this worked for us:

---

Kernel does not support a non-PAE CPU install KVM guest on Ubuntu 13.10 – Fix

...

Basically, you just need to ensure that the linux-image-generic package (i.e. a kernel which supports non-PAE CPU’s) is installed by setting the addpkg flag like so:

--addpkg=linux-image-generic
