I think this is not entirely accurate. Right now the term "dom0" is a mix of "has access to host (IO) hardware" and "runs the toolstack". ConditionVirtualization= today lacks such details as well. "xen" means domU, and "none" is dom0, simply to handle "dom0" like "native" so that all services that want access to "host hardware" can start. One could argue that passing a PCI device to a domU may also require .service files to manage that PCI device in some way. The specifc case which triggered all the suggested changes was smartd, which is not supposed to run in "VMs". If a SATA card is provided to a domU it may be a good idea to monitor the attached disks as well. So in some way Jan is correct with his suggestion to use XENFEAT_dom0 instead of "control_d". I will do some research about when it became available and update the patch description. Olaf Attachment:
