Xen devel - Sep 2011 - help: monitor table and hap

Hi,

I''m trying to figure what the purpose of monitor_table is? It seems to
be used for shadow_mode_external, which I understand doesn''t apply to
HAP mode? 

thanks,
Mukesh

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.
