Hm... but then setting that variable to python3 should work, but based on the list reports - it doesn't work. Best Regards, Strahil Nikolov На 17 юли 2020 г. 12:35:52 GMT+03:00, Gianluca Cecchi <gianluca.cecchi@gmail.com> написа:

Hi Gianluca,
that's very strange error, because I'm 100% sure we are using yum module with Python3 in several other roles including adding host to engine or upgrading host and so far I haven't heard any issue with ansible 2.9.10 and yum module.
Gobinda, wouldn't enforcing python interpreter version help there?

I have a very clean install from 4.1.1.1 node ng iso anf I'm the third to notice that with this release. The engine deployment is going on. Not finished yet, but to have ti go I had to modify, with the same strategy ("use: dnf" with package module and use "package" instead of "yum" and also specifying "use: dnf") in these files under /usr/share/ansible/roles:
ovirt.engine-setup/tasks/engine_setup.yml ovirt.engine-setup/tasks/install_packages.yml ovirt.hosted_engine_setup/tasks/install_packages.yml
ovirt.hosted_engine_setup/tasks/create_target_vm/03_hosted_engine_final_tasks.yml
ovirt.hosted_engine_setup/tasks/install_appliance.yml
Gianluca
The installation from the iso was with all default values. The only "non standard" thing, if we want it to call this way is that before running the wizard, on the host I pre-installed the appliance package, to shorten the deploy phase hereafter. And to do it I executed, because of habit: yum install ovirt-engine-appliance
instead of "dnf install...", but I think this doesn't influence ansible autodetect when using "package" module or the error about python2 when using "yum" module...
Gianluca
The engine deployment failed in the phase where it tries to add the host and waits for the host to be up and if I go into the logs in
/var/log/ovirt-hosted-engine-setup/engine-logs-2020-07-17T08:30:48Z/ovirt-engine/host-deploy/
the file
ovirt-host-deploy-ansible-20200717104103-novirt2.example.net-3a710f0c.log
contains
020-07-17 10:41:17 CEST - fatal: [novirt2.example.net]: FAILED! => {"changed": false, "module_stderr": "/bin/sh: /usr/bin /python2: No such file or directory\n", "module_stdout": "", "msg": "The module failed to execute correctly, you probably need to set the interpreter.\nSee stdout/stderr for the exact error", "rc": 127} 2020-07-17 10:41:17 CEST - { "status" : "OK", "msg" : "", "data" : { "uuid" : "00f4c6a8-8423-4a2a-bfd5-f38c34f56ecf", "counter" : 53, "stdout" : "fatal: [novirt2.example.net]: FAILED! => {\"changed\": false, \"module_stderr\": \"/bin/sh: /usr/bin/pytho n2: No such file or directory\\n\", \"module_stdout\": \"\", \"msg\": \"The module failed to execute correctly, you probab ly need to set the interpreter.\\nSee stdout/stderr for the exact error\", \"rc\": 127}",
So I think I have to find and solve why it searches python2.... I compared on an existing 4.4.0 environment I have (hci single node installed from 4.4.0 node ng iso) and no python2 apparently there, only ansible that is at ansible-2.9.9-1.el8.noarch instead of ansible-2.9.10-1.el8.noarch of 4.4.1.1
Possibly any wrong default about python?
Alternatives seems the same between 4.4.0 and 4.4.1.1

Not sure where to search if not somehow a bug of ansible 2.9.10 Can I try to clean install a 4.4.1.1 host and downgrade ansible before deploy, eg running
rpm -Uvh --oldpackage ansible-2.9.9-1.el8.noarch ?
Where to get the 2.9.9 rpm to apply in case, just to exclude it?

Inside ovirt-host-deploy-ansible-20200717104103-novirt2.example.net-3a710f0c.log at the beginning the gathering of facts seems all ok and python3, but then I see this:

and then the failure because the ansible_python_intepreter has been set to pythin2
