From aaac044c06d93bd90ffa35eb091ec10c67f3ef7e Mon Sep 17 00:00:00 2001

Subject: [PATCH] pc: fail memory hot-plug/unplug with -no-acpi and Q35 machine
type
When -no-acpi option is used with Q35 machine type, no guest ACPI is
built, but the ACPI device is still created, so only checking the
presence of ACPI device before memory plug/unplug is not enough in
such cases. Check whether ACPI is disabled globally in addition and
fail memory plug/unplug if it's disabled.
