I'll hold off on the whole thing - frankly, we don't want this kind of Xen-only complexity. If KVM can make use of PLE then Xen ought to be able to do it as well.
It does - for fully virtualized guests. For para-virtualized ones, it can't (as the hardware feature is an extension to VMX/SVM).
If both Xen and KVM makes good use of it then that's a different matter.
I saw in a later reply that you're now tending towards trying it out at least - thanks. Jan
