I get these for both PV and HVM guests. These messages simply indicate that the guest didn't do some expected cleanup itself. I see these too when Dom0 shuts down, at least for certain drivers. For HVM arguably qemu might know better and tear things down properly, but in no event are these messages - when occurring in connection with a guest going down - indications of a problem. We could even see to lower their severity or suppress them altogether when the domain is known to be dying (you may want to check whether ->is_dying is already set at that point).
