# HG changeset patch # User Paul Durrant <paul.durrant@xxxxxxxxxx> # Date 1321546881 0 # Node ID 447738ef67ea2690c8ea6684f2e0e0b3528ad446 # Parent dbdc840f8f62db58321b5009e5e0f7833066386f Move acpi_enabled out of hvm_info_table into xenstore Since hvmloader has a xentore client, use a platform key in xenstore to indicate whether ACPI is enabled or not rather than the shared hvm_info_table structure.
