Hi How do we get the number of page faults done by a guest in a scheduling epoch? Assuming only one VCPU per guest, can I get it from vcpu_info[]? I hope this is not a vey trivial question :) thanks Chintu -- View this message in context: http://xen.1045712.n5.nabble.com/Getting-the-page-fault-count-for-domU-tp4847541p4847541.html Sent from the Xen - Dev mailing list

ging_prep ensures that an mfn is backing the paged-out gfn, and transitions to the next state in the paging state machine for this page. Foreign mappings of the gfn will now succeed. This is the key idea, as it allows the pager to now map the gfn and fill in its contents. Unfortunately, it also allows any other foreign mapper to map the gfn and read its contents. This is particularly dangerous
