A new 'target' subelement of the pci-root controller has been introduced having
a 'hotplug' property. This proprty can be used to turn off or turn on hotplug
capability of the devices plugged into the pci-root ports. This change release
notes this feature for the next release.
The new element can be used like this:
<controller type='pci' model='pci-root'>
<target hotplug='off'/>
</controller>
This will turn off hotplug capability on the pci-root ports. To turn the
capability on, we set hotplug='on' above (which is also the default).
