[ovirt-devel] Re: Error during deployment of self hosted engine oVirt 4.4

Hi guys, I am trying to install oVirt 4.4 for testing of the aSPICE and Opaque Android clients and tried to follow this slightly outdated doc: https://www.ovirt.org/documentation/installing_ovirt_as_a_self-hosted_eng... to deploy an all-in-one self-hosted engine using the command-line. I started with a clean CentOS 8 installation, set up an NFS server and tested that mounts work from the local host and other hosts, opened all ports with firewalld to my LAN and localhost (but left firewalld enabled). During the run of hosted-engine --deploy I got the following error: 2020-08-03 23:31:51,426-0400 DEBUG otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:103 TASK [ovirt.hosted_engine_setup : debug] 2020-08-03 23:31:51,827-0400 DEBUG otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:103 server_cpu_dict: {'Intel Nehalem Family': 'Nehalem', 'Secure Intel Nehalem Family': 'Nehalem,+sp ec-ctrl,+ssbd,+md-clear', 'Intel Westmere Family': 'Westmere', 'Secure Intel Westmere Family': 'Westmere,+pcid,+spec-ctrl,+ssbd,+md-clear', 'Intel SandyBridge Family': 'SandyBridge', 'Secure Intel SandyBridge Fa mily': 'SandyBridge,+pcid,+spec-ctrl,+ssbd,+md-clear', 'Intel IvyBridge Family': 'IvyBridge', 'Secure Intel IvyBridge Family': 'IvyBridge,+pcid,+spec-ctrl,+ssbd,+md-clear', 'Intel Haswell Family': 'Haswell-noTSX ', 'Secure Intel Haswell Family': 'Haswell-noTSX,+spec-ctrl,+ssbd,+md-clear', 'Intel Broadwell Family': 'Broadwell-noTSX', 'Secure Intel Broadwell Family': 'Broadwell-noTSX,+spec-ctrl,+ssbd,+md-clear', 'Intel Sk ylake Client Family': 'Skylake-Client,-hle,-rtm', 'Secure Intel Skylake Client Family': 'Skylake-Client,+spec-ctrl,+ssbd,+md-clear,-hle,-rtm', 'Intel Skylake Server Family': 'Skylake-Server,-hle,-rtm', 'Secure I ntel Skylake Server Family': 'Skylake-Server,+spec-ctrl,+ssbd,+md-clear,-hle,-rtm', 'Intel Cascadelake Server Family': 'Cascadelake-Server,-hle,-rtm,+arch-capabilities', 'Secure Intel Cascadelake Server Family': 'Cascadelake-Server,+md-clear,+mds-no,-hle,-rtm,+tsx-ctrl,+arch-capabilities', 'AMD Opteron G4': 'Opteron_G4', 'AMD Opteron G5': 'Opteron_G5', 'AMD EPYC': 'EPYC', 'Secure AMD EPYC': 'EPYC,+ibpb,+virt-ssbd', 'IB M POWER8': 'POWER8', 'IBM POWER9': 'POWER9', 'IBM z114, z196': 'z196-base', 'IBM zBC12, zEC12': 'zEC12-base', 'IBM z13s, z13': 'z13-base', 'IBM z14': 'z14-base'} 2020-08-03 23:31:52,128-0400 INFO otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:109 TASK [ovirt.hosted_engine_setup : Convert CPU model name] 2020-08-03 23:31:52,530-0400 DEBUG otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:103 {'msg': "The task includes an option with an undefined variable.
