Guest-programmable location of advanced configuration and power interface (ACPI) tables in virtualized systems

摘要

A system and method are disclosed for guest-programmable relocation of system tables in a virtualized computer system. In accordance with one embodiment, a hypervisor that is executed by a computer system obtains a first base address of a first portion of memory, where the first base address is in an address space of a guest of a virtual machine, and where the first base address is for a set of one or more system tables that is currently exposed by the hypervisor at a second portion of memory having a second base address in the address space of the guest. The hypervisor then generates a new version of the set of one or more system tables that is exposed to the guest at the first base address.
