The breakage happened due to:
- ansible-core recently moved to python 3.9
- oVirt needs several python libraries in its use of ansible, some of
which are packaged by oVirt. Those are not yet built for python 3.9.

python38-netaddr might be installed, but python39-netaddr is probably not.

For the time being, try to downgrade ansible-core to 2.12, or the last
version requiring python 3.8.
We merged this patch to the engine master branch (to eventually become 4.5.3):
https://github.com/oVirt/ovirt-engine/pull/654
Going forward:
1. We hope to finish porting the engine to CS9 soon, and if this
proves stable, consider dropping support for CS8.
2. We might try, in the time being, to build the missing dependencies
for python 3.9. It's not clear if it's worth the effort.
Best regards,
