Hi Jonas,

I get the same error when I try to install. Last weekend I managed to do it (but with a lot of other problems) so something has changed during the week.

After the VM is up I logged in through ssh and saw that the oVirt appliance comes with Python-3.6 and Python-3.8 which both have netaddr installed.

Part of the log:
...
[ INFO  ] TASK [ovirt.ovirt.engine_setup : Update setup packages]
[ INFO  ] skipping: [localhost]
[ INFO  ] TASK [ovirt.ovirt.engine_setup : Copy yum configuration file]
[ INFO  ] changed: [localhost -> 192.168.222.35]
[ INFO  ] TASK [ovirt.ovirt.engine_setup : Set 'best' to false]

[ INFO  ] TASK [ovirt.ovirt.engine_setup : Set offline parameter if variable is set]
...
I noticed that after the task "Update all packages" Python-3.9 gets installed and that version does not have netaddr installed. My theory is that the playbook somehow uses the newest version of Python which is installed.

pip3.9 list

Package      Version
------------ -------
ansible-core 2.13.3
cffi         1.14.3
cryptography 3.3.1
idna         2.10
pip          20.2.4
ply          3.11
pycparser    2.20
PyYAML       5.4.1
setuptools   50.3.2

six          1.15.0

I have tried another run where I installed the netaddr module as soon as Python-3.9 got installed and that installation went further but then it had another error.

When I log into my hosted engine VM from last week there is no Python-3.9.

My dnf(1) skills are not good enough to figure out which dependency is causing Python-3.9 to be installed.

There are probably a lot of other modules missing that can explain the other error(s) I see.

I will see if I can find out how to file a proper bug report.
