Hi, Is it actually first attempt to install HE? Or maybe you ran into some (different) problem and this is like second (third, fourth…) attempt. While installation script takes care of some cleanup, I would say that you should consider doing ovirt-hosted-engine-cleanup ,checking that virbr0 is absent in ‘ip a’ output and trying once again BR, Konstantin Von: lejeczek via Users <users(a)ovirt.org&gt; Antworten an: lejeczek <peljasz(a)yahoo.co.uk&gt; Datum: Donnerstag, 11.

Hi, maybe you should do virsh net-undefine default virsh net-destroy default And maybe there is some change in Libvirt and ovirt-hosted-engine-cleanup doesn’t cleanup default network (which results in virbr0 interface) (and at the same time this Ansible code is not idempotent) BR, Konstantin P.S.

Any & all suggestions on how to fix/troubleshoot this are much appreciated. many thanks, L. No, it is a clean install of oVirt node in a KVM guest/VM. All I do in the node is I configure two ifaces and both are "regular" ethernets, then I start HE setup. Bare-metal host is Centos 9 Stream with everything up-to-dayte off the distro repos. I'd think this should be easily reproducible. ps. please keep replies to the bottom - this is not a conversion between two of us nor any two persons, Mailing to list - think of it a book, which always reads top-to-bottom. many thanks, L.
