Various Linux versions allocate (partial) per-CPU data for all of them, as there is no indication in MADT whether they're hotpluggable. That's a little wasteful in terms of resource consumption especially for - guests with not overly much memory assigned, - 32-bit guests not having overly much address space available. Therefore limit what we put into MADT to the "maxvcpus" value, and make sure AML doesn't touch memory addresses corresponding to CPUs beyond that value (we can't reasonably make the respective processor objects disappear).

ACPI Table for domain firmware INSTALL ----------------- Simply make is OK. # make Note on DSDT Table ------------------ DSDT table source code is acpi_dsdt.asl It is already compiled and the output is acpi_dsdt.c Usually, user is not expected to change the acpi_dsdt.asl. In case that the acpi_dsdt.asl need to be updated, please Follow the instruction: # make acpi_dsdt.c Note: DSDT compiler "iasl" is needed. By default, it will be downloaded using wget in Makefile. if it failed, please download manually from http://developer.intel.com/technology/iapc/acpi/downloads.htm. then compile and install iasl
