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). Signed-off-by: Ani Sinha <ani@xxxxxxxxxxx> Reviewed-by: Daniel P.
