I don't use ansible for the deployment of the hosted engine right now, but like I said the ovirt-hosted-engine-setup:command. Can you tell me where I can find the required ansible plays, then I'll try.

You can try: hosted-engine --deploy --otopi-environment=OVEHOSTED_CORE/pauseonRestore=bool:True This is setting the ansible var he_pause_host: https://github.com/oVirt/ovirt-ansible-hosted-engine-setup/

Can you tell me where I can find the required ansible plays, then I'll try.

Good luck and best regards, -- Didi

Hi Didi,

thanks for your input, sadly this doesn't change anything of the described behavior. (Also just to mention: It takes way less then a second to get to the cleanup - in case this provides some hints)

It does - and also the full log below. It means it fails on the host, not inside the engine vm. It probably fails because our internal "minidnf" does not support all the stuff you try to do to dnf. engine-setup has an option '--offline', but sadly hosted-engine --deploy does not have it. You can try: hosted-engine --deploy --otopi-environment=PACKAGER/dnfpackagerEnabled=bool:False Or perhaps: hosted-engine --deploy --otopi-environment="PACKAGER/dnfpackagerEnabled=bool:False PACKAGER/yumpackagerEnabled=bool:False" I think this should be enough, didn't try.

It probably fails because our internal "minidnf" does not support all the stuff you try to do to dnf. This seems to be the case.

You can try:

hosted-engine --deploy --otopi-environment=PACKAGER/dnfpackagerEnabled=bool:False This Works!

Thanks a lot for your support!

You are welcome, thanks for the report! :-)

For anyone stumbling upon this at a later point: This workaround might work for you, if you made changes to /etc/dnf/dnf.conf for dnf to work on your CentOS8 instance. In our case the problem was the proxy authentication method dnf uses.

Actually, AFAICT, we never really need dnfpackager anymore, as all the very little logic around installing/removing the appliance is now done in ovirt-ansible-hosted-engine-setup. So it's safe to always use (and thus skip the lengthy dnf cache update etc.). Feel free to open a bug to get this removed and use an "offline packager" (like --offline in engine-setup).
