Hi Paul, Thank you for your help understanding the resource code.

If the DM domain is not PV then currently it must be the hardware domain to be able to map resources. Hence we trust it not to descrease_reservation IOREQ pages.
Can you point me to check in the code? The only check I found is: !(xmar.flags & XENMEM_rsrc_acq_caller_owned) && !is_hardware_domain(d) But this is still allowing to map some of the resources in a DM domain.
