https://progress.opensuse.org/issues/162284 Prevent multi-machine tests to be picked up if os-autoinst-openvswitch service does not work size:M ## Observation During unintended upgrade of worker31 and others to Leap 15.6 the network did only come up after 20m(!) for yet unknown reasons, see #157975. Additional problems were caused because os-autoinst-openvswitch timed out eventually but then openQA workers picked up and destroyed jobs happily with ``` backend died: Open vSwitch command 'set_vlan' with arguments 'tap37 121' failed: org.freedesktop.DBus.Error.ServiceUnknown: The name org.opensuse.os_autoinst.switch was not provided by any .service files ``` Fabian Vogt suggests: "Instead of relying on the systemd .service to be enabled and running you could add a dbus .service file with a SystemdService= key to make use of dbus autolaunch" ## Acceptance criteria * **AC1:** openQA workers do not pick up multi-machine tests if the os-autoinst openvswitch service is not available over DBUS * **AC2:** openQA workers clearly communicate this problematic can still pick up non-multi-machine tests in that situation ## Suggestions * Look into the suggestion by fvogt * Make the worker check for the availability of the requested DBUS service or something *if* it has a multi-machine worker class and make the worker show up as "broken" which we already use in other cases * As alternative look into the suggestion by fvogt but that would still rely on systemd * As alternative to declaring the worker "broken" remove the "tap" class dynamically or change it to "tap_broken_$reason"
