Hi, when I experiment with installing a RHEL 8 host from Engine (master branch running on RHEL 7), I get the following error in host deploy: 2019-06-25 12:59:48,701+0200 DEBUG otopi.plugins.otopi.network.firewalld firewalld._get_firewalld_cmd_version:116 firewalld version: 0.6.3 2019-06-25 12:59:48,701+0200 DEBUG otopi.plugins.otopi.dialog.machine dialog.__logString:204 DIALOG:SEND **%EventEnd STAGE customization METHOD otopi.plugins.otopi.network.firewalld.Plugin._customization (None) 2019-06-25 12:59:48,701+0200 DEBUG otopi.context context.dumpEnvironment:731 ENVIRONMENT DUMP - BEGIN 2019-06-25 12:59:48,702+0200 DEBUG otopi.context context.dumpEnvironment:741 ENV NETWORK/firewalldAvailable=bool:'True' 2019-06-25 12:59:48,702+0200 DEBUG otopi.context context.dumpEnvironment:745 ENVIRONMENT DUMP - END 2019-06-25 12:59:48,702+0200 DEBUG otopi.context context._executeMethod:127 Stage customization METHOD otopi.plugins.otopi.core.config.Plugin._customize1 2019-06-25 12:59:48,702+0200 DEBUG otopi.plugins.otopi.dialog.machine dialog.__logString:204 DIALOG:SEND **%EventStart STAGE customization METHOD otopi.plugins.otopi.core.config.Plugin._customize1 (None) 2019-06-25 12:59:48,703+0200 DEBUG otopi.plugins.otopi.dialog.machine dialog.__logString:204 DIALOG:SEND **%EventEnd STAGE customization METHOD otopi.plugins.otopi.core.config.Plugin._customize1 (None) 2019-06-25 12:59:48,703+0200 DEBUG otopi.context context._executeMethod:127 Stage customization METHOD otopi.plugins.ovirt_host_deploy.kdump.packages.Plugin._customization 2019-06-25 12:59:48,703+0200 DEBUG otopi.plugins.otopi.dialog.machine dialog.__logString:204 DIALOG:SEND **%EventStart STAGE customization METHOD otopi.plugins.ovirt_host_deploy.kdump.packages.Plugin._customization (None) 2019-06-25 12:59:48,704+0200 DEBUG otopi.context context._executeMethod:145 method exception Traceback (most recent call last): File "/tmp/ovirt-AX5hJa1Fcr/pythonlib/otopi/context.py", line 132, in _executeMethod method['method']() File "/tmp/ovirt-AX5hJa1Fcr/otopi-plugins/ovirt-host-deploy/kdump/packages.py", line 216, in _customization self._kexec_tools_version_supported() File "/tmp/ovirt-AX5hJa1Fcr/otopi-plugins/ovirt-host-deploy/kdump/packages.py", line 143, in _kexec_tools_version_supported from rpmUtils.miscutils import compareEVR ModuleNotFoundError: No module named 'rpmUtils' 2019-06-25 12:59:48,705+0200 ERROR otopi.context context._executeMethod:154 Failed to execute stage 'Environment customization': No module named 'rpmUtils' It's apparently because `rpmUtils' module from `yum' package is no longer present on RHEL 8 (in `yum' or another very easily guessable package). I'm not sure how el7 x el8 host installation is supposed to work and whether I can do anything at the moment to proceed a bit further. I suppose similar yum x dnf issues will need some attention; not only in host deploy but everywhere where yum or rpm manipulation is used. Thanks, Milan
