Source: xen Package: xen-hypervisor-4.4-amd64 Version: 4.4.1-9+deb8u8 When the xen hypervisor is updated there's no specific indication that the system should be rebooted whereas this is as important to notify as a kernel upgrade.
I suggest the xen-hypervisor*.postinst calls : /usr/share/update-notifier/notify-reboot-required Thanks, Sébastien
