Hi,

paging_mode_external(d) is true for all HVM guests, including HAP ones.
It means that the Xen virtual addresses aren't reserved in guest
pagetables (the way they are in PV guests). 

The monitor_table, in those cases, is the set of pagetables that Xen
runs on when that guest's VCPUs are scheduled (e.g. in VMEXIT handlers).

Cheers,

Tim.
