[Xen-devel] PV Memory Management

["Mike Sun" <msun@xxxxxxxxxx>]

Hi --

I'm finding myself a bit confused about the PV memory management.

My first question is whether page table type pages are pinned and not
allowed to be swapped by the guest OS.  If this is the case, how is
memory pinning accomplished by Xen?

Secondly, how does Xen keep track of which mfns allocated to a guest
domain are of what type (i.e. which frames are page table frames)?

Any help would be greatly appreciated,
Mike
