Starting LSB: Bring up/down networking... [FAILED] Failed to start LSB: Bring up/down networking. See 'systemctl status network.service' for details. A "systemctl restart network" ends with a error I mean without NetworkManager I have always this Error in KVM Clients now, with Update 1810 ? I have found a workaround for me in the Momemt. I enable NetworManager on boot and disable NetworkManager in the ifcfg-ethX files Now the most time the clients are starting with a working Network ?? > > Is this only on my computers or have other also this Problem? > > > > Is the bridge software is broken ? > > What does your system report in the relevant log files? > > > Can I use openvswitch to replace bridge Software? > > Sure you can.

KVM/Linux bridging often defaults to have spanning tree enabled which many switches do not like. Try creating the bridge and disable spanning tree? ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

I have 3 host computer on different places, but all have the Problem when starting a client "KVM" to connect to the bridge from the host. It is near not possible to start a client, only after 10-20 reboot/restart from the client's the network is starting correct? Logs are the only source of truth. Without them everything is pure speculation. Is this only on my computers or have other also this Problem? Is the bridge software is broken ? What does your system report in the relevant log files? Can I use openvswitch to replace bridge Software? Sure you can. It takes a bit more effort to setup openvswitch. It can be worth it depending on your network design. Any help are welcome ;-) First of all it would be necessary from your side to provide details about your setup. Running KVM with a bridge setup is not enough info. Get your config sorted and the logs. Alexander ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
[CentOS] KVM Bridge Problem
Hello, is this only my mistake,or can help any from the list? I have 3 host computer on different places, but all have the Problem when starting a client "KVM" to connect to the bridge from the host. It is near not possible to start a client, only after 10-20 reboot/restart from the client's the network is starting correct? Is this only on my computers or have other also this Problem? Is the bridge software is broken ? Can I use openvswitch to replace bridge Software? Any help are welcome ;-) -- mit freundliche Grüßen / best regards, Günther J.
