- ==================== ========================================================================================================= ======= ==============
- Feature Description Value Since
- ==================== ========================================================================================================= ======= ==============
- acpi-bridge-hotplug Enable ACPI based hotplug on the cold-plugged PCI bridges (pc) and pcie-root-ports (q35) (also see notes) on, off :since:`7.9.0`
- ==================== ========================================================================================================= ======= ==============
-
- Note: pc machine types (i440fx) have ACPI hotplug enabled by
- default on cold plugged bridges (bridges that were present in the
- VM's domain definition before it was started). Disabling ACPI
- hotplug leaves only SHPC hotplug enabled; many OSes don't
- support SHPC hotplug, so this may have the effect of completely
- disabling hotplug.
-
- On q35 machinetypes earlier than pc-q35-6.1 (regardless of the QEMU
- binary version), ACPI hotplug for cold plugged bridges is disabled
- by default, and native PCIe hotplug is enabled instead. Enabling
- ACPI hotplug will disable native PCIe hotplug.
-
- Starting with the pc-q35-6.1 machinetype, ACPI hotplug is enabled
- on cold plugged bridges by default while native PCIe hotplug is
- disabled. In this case, disabling ACPI hotplug will re-enable PCIe
- native hotplug.
-
``pmu``
Depending on the ``state`` attribute (values ``on``, ``off``, default ``on``)
enable or disable the performance monitoring unit for the guest.
