Currently, those settings are not supported by libvirt. Do you need to adjust 
them for PCI passthrough to PV domains?

I took a quick peek at xl.cfg(5) and based on the description of those settings 
didn't see a counterpart in the libvirt domain schema. Perhaps understanding 
use-cases will help with modeling those settings in libvirt domain XML.
