Hi, I have exactly the same problem, i want to add a host (centos 6.2) in ovirt, and i have the same error. It is very strange, here logs : <BSTRAP component='VDS PACKAGES' status='OK' result='libselinux-python' message='libselinux-python-2.0.94-5.2.el6.x86_64 '/> <BSTRAP component='CreateConf' status='FAIL' message='Basic configuration failed to import default values'/> <BSTRAP component='RHEV_INSTALL' status='FAIL'/> . Error occured. (Stage: Running first installation script on Host) 2012-05-03 03:37:40,538 INFO [org.ovirt.engine.core.utils.hostinstall.MinaInstallWrapper] (pool-5-thread-50) RunSSHCommand returns true 2012-05-03 03:37:40,538 INFO [org.ovirt.engine.core.bll.VdsInstaller] (pool-5-thread-50) RunScript ended:true 2012-05-03 03:37:40,539 ERROR [org.ovirt.engine.core.bll.VdsInstaller] (pool-5-thread-50) Installation of 192.168.10.19.

Step: CreateConf; Details: Basic configuration failed to import default values. I tried to disable ssl in engine and vdsm but it is the same. I have searched more explications into vdsm and ovirt log but I have found anything I suppose vdsm to be the problem, the only way to build it with success is to install it on F17, which is a beta release... This makes me crazy! May anybody help me to find a clue for this issue? on Node side, can you please share /tmp/vds_* logs? rpm -qa | grep vdsm (from oVirt Node and oVirt engine) As we resolved this case by irc, here the reply to mailing list: ============= The error from logs: Fri, 27 Apr 2012 14:55:24 DEBUG <BSTRAP component='VDS PACKAGES' status='OK' result='libjpeg' message='le paquetage libjpeg n~est pas installé '/> Fri, 27 Apr 2012 14:55:24 ERROR Traceback (most recent call last): File "/tmp/vds_bootstrap_9e3dc61c-4ef8-4c42-873c-6209c522ac4c.py", line 594, in createConf self._makeConfig() File "/tmp/vds_bootstrap_9e3dc61c-4ef8-4c42-873c-6209c522ac4c.py", line 557, in _makeConfig from config import config ImportError: No module named config Fri, 27 Apr 2012 14:55:24 DEBUG <BSTRAP component='CreateConf' status='FAIL' message='Basic configuration failed to import default values'/> Fri, 27 Apr 2012 14:55:24 ERROR createConf failed Fri, 27 Apr 2012 14:55:24 DEBUG <BSTRAP component='RHEV_INSTALL' status='FAIL'/> Fri, 27 Apr 2012 14:55:24 DEBUG **** End VDS Validation **** ========= On Engine side Nathanaël's machine had: vds_bootstrap version (vdsm-bootstrap-4.9.3.2-0.fc16.noarch) which had to update to a newer version: 4.9.6 copied new vds_bootstrap files from: /usr/share/vds_bootstrap to /usr/share/ovirt-engine/engine.ear/components.war/vds and removed any *.pyc and *.pyo from there.
