[ovirt-devel] unable to add host(s)

Hi, I have some hosts which are resilient to my effort to add them into engine: 1. produces some error about iptables: 2017-09-27 11:45:29,711+0300 DEBUG otopi.plugins.otopi.services.systemd plugin.executeRaw:813 execute: ('/usr/bin/systemctl', 'enable', u'iptables.service'), executable='None', cwd='None', e nv=None 2017-09-27 11:45:29,717+0300 DEBUG otopi.plugins.otopi.services.systemd plugin.executeRaw:863 execute-result: ('/usr/bin/systemctl', 'enable', u'iptables.service'), rc=1 2017-09-27 11:45:29,717+0300 DEBUG otopi.plugins.otopi.services.systemd plugin.execute:921 execute-output: ('/usr/bin/systemctl', 'enable', u'iptables.service') stdout: 2017-09-27 11:45:29,717+0300 DEBUG otopi.plugins.otopi.services.systemd plugin.execute:926 execute-output: ('/usr/bin/systemctl', 'enable', u'iptables.service') stderr: Failed to execute operation: No such file or directory 2017-09-27 11:45:29,718+0300 DEBUG otopi.context context._executeMethod:143 method exception Traceback (most recent call last): File "/tmp/ovirt-5BawtgI21o/pythonlib/otopi/context.py", line 133, in _executeMethod method['method']() File "/tmp/ovirt-5BawtgI21o/otopi-plugins/otopi/network/iptables.py", line 108, in _closeup self.services.startup('iptables', True) File "/tmp/ovirt-5BawtgI21o/otopi-plugins/otopi/services/systemd.py", line 122, in startup service=name, RuntimeError: Failed to enable service 'iptables' 2017-09-27 11:45:29,720+0300 ERROR otopi.context context._executeMethod:152 Failed to execute stage 'Closing up': Failed to enable service 'iptables' • see ovirt-host-deploy-20170927104530-vm-18-133.eng.lab.tlv.redhat.com-310be768.log in attachment • but perpetual effort and retries seems to fix this, so I did not get this one again. 2. generally hosts tries to install uninstallable cockpit-whatever and other non existant libraries, which I can overcome with /etc/ovirt-host-deploy.conf.d/50-offline-packager.conf, but it's making whole process kinda very slow. Is there a better way? 3. and finally host vm-17-100.eng.lab.tlv.redhat.com responds to same treatment (disabling package manager, multitude of retries to install host and do yum updates before installing host ) differently, and now it always became nonresponsive upon installation, without any information (apparently to me) in logs. Otherwise host function pretty normal, it only cannot be added to engine. check ovirt-host-deploy-20170927105857-vm-17-100.eng.lab.tlv.redhat.com-e01e0dd4-c0cc-499d-8f1f-6d0b12b64804.log in attachment. ———— am I doing something wrong? Or is this a bug? If you need any further information, please ask. I can retry any time, possibly with different host. M.
