Sorry, correction, the new ansible core uses python 3.11, which is the problematic one,
3.9 is ok with the old ansible-core.

Hi,
please try downgrading ansible-core, the new ansible-core uses python 3.9 for which the
modules are missing. In my installation downgrading ansible-core solves the problem, until
this is resolved upstream.
Cheers,
Alessandro

ovirt-engine.my.cluster)? If I have no entry for the engine in the DNS I get the following

192.168.0.222 (this is an ip address on the host subnet; but the engine gets a DHCP
address from a different subnet from a virtual network from the host; I dont understand
this) which moves away from the above problem and goes all the way (after providing the
values for a few other questions) to hang at
