I'm trying, without much success, to figure out what the status is on shadow page tables. Specifically I'm interested in using fully translated/external shadow page tables. Referring to [1] it seems that, as 32bit x86 non-pae still uses shadow32.c, shadow.c is not quite ready for 32bit. Furthermore I assume that shadow32.c only supports shadow page tables that are located in the individual VMs and are maintained by the guest OSes. Can anyone confirm this or elaborate on when a working version of external
shadow page tables in shadow.c can be expected in a 32bit version?

shadow32.c already supports fully translated and external pagetables.
