Hi again! After rebooting the server an cleaning up everything in /etc/systemd/network/ it does work again (kayobe overcloud host configure) but I am afraid to run “kayobe overcloud service deploy”. Can anyone confirm that the configuration might be correct or has an idea about what happened in the network there? Multicast storm? Broadcast storm? Troubles with STP? Thank you and best wishes Stefan ________________________________ BearingPoint GmbH Sitz: Wien Firmenbuchgericht: Handelsgericht Wien Firmenbuchnummer: FN 175524z The information in this email is confidential and may be legally privileged.
