KVM is generally better for laptops because of better power
management. However ...

Is KVM enabled?
$ /sbin/lsmod | grep kvm
kvm_intel 48184 6
kvm 163952 1 kvm_intel
You should see a kvm_* module. Does your laptop support hardware
virtualization? Recent hardware has much better support than the
first generation of hardware. Is it enabled in the laptop BIOS?

Fedora 12 doesn't support Xen as a host. Too bad, but this
is because upstream Xen people didn't get their changes into the Linux
Your options are to go back to something out of date and unsupported
(Fedora 8 IIRC was the last version of Fedora that could be used as a
Xen host). Or use KVM -- see above. Or use RHEL 5 or a derivative
where an older version of Xen is fully supported.
