A previous proposal patch 5 was rejected because of those issues [1]. The fixes have been validated in the Jailhouse setup, where we add and remove a virtual PCI host controller on hypervisor activation/ deactivation, with the help of kmemleak. Besides that, there is tiny PCI API cleanup at the beginning and support for manually enabled PCI domains at the end that enables the Jailhouse scenario.
