Hi Fabrice,
Indeed, it does look very similar, but I think it's not quite the same
(but could be wrong).
For starters, the fix by appending the extra clauses in the when: block
in configure.yml did not help me. In my case, it appears the engine is
trying to run the following when setting up the first host:
vdsm-tool ovn-config 10.110.115.21 hv1-mgmt.cds.ligo-la.caltech.edu
Note that this IP and hostname both point to the host that is being added.
But the help info for vdsm-tool shows that another argument is needed
for the IP of the engine itself:
[root@hv1 ~]# vdsm-tool ovn-config
usage:
/usr/bin/vdsm-tool [options] ovn-config IP-central
[tunneling-IP|tunneling-network] host-fqdn
Configures the ovn-controller on the host.
Parameters:
IP-central - the IP of the engine (the host where OVN central is
located)
tunneling-IP - the local IP which is to be used for OVN tunneling
tunneling-network - the vdsm network meant to be used for OVN tunneling
host-fqdn - FQDN that will be set as system-id for OvS (optional)
So either the engine is omitting this argument, or it's misinterpreting
the host's IP address as the engine's IP address. If I manually run
this vdsm-tool command with the extra engine IP address as an argument,
it appears to work:
vdsm-tool ovn-config 10.110.115.20 10.110.115.21
hv1-mgmt.cds.ligo-la.caltech.edu
I'm not fluent enough in ansible to know where I can make the fix to add
this extra argument, unfortunately.
The host is running Rocky Linux 9:
[root@hv1 ~]# rpm -qf /usr/bin/vdsm-tool
vdsm-python-4.50.5.1-1.el9.noarch

What is the recommended combination to use for new installs?

(ovirt-engine-appliance-4.5-20231201120201.1.el9) was still based on CentOS8-stream.
Using --ansible-extra-vars=he_pause_before_engine_setup=true I was able to redirect the
repos to vault.centos.org. This helped, but still failed when the engine tried to access
the host:

installed ovirt-engine-appliance-4.5-20240817071039.1.el9.x86_64.rpm and tried again. But
of course that failed because the host and engine now have incompatible versions:
