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. Sorry, I will top-post…

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

Hi guys.

I'm trying to setup the engine on the latest stable ovirt node(in a VM), so a clean, vanilla-default system.

-> $  hosted-engine --deploy --4
...
[ INFO  ] TASK [ovirt.ovirt.hosted_engine_setup : Activate default libvirt network]
[ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "cmd": ["virsh", "net-start", "default"], "delta": "0:00:00.042134", "end": "2023-05-11 11:08:59.248405", "msg": "non-zero return code", "rc": 1, "start": "2023-05-11 11:08:59.206271", "stderr": "error: Failed to start network default\nerror: error creating bridge interface virbr0: File exists", "stderr_lines": ["error: Failed to start network default", "error: error creating bridge interface virbr0: File exists"], "stdout": "", "stdout_lines": []}
[ ERROR ] Failed to execute stage 'Closing up': Failed getting local_vm_dir

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.
