Now that I have one VM as a host in the UP state in ovirt-engine, let me capture what I needed to get that to work: On my F16-node, since I was following the test day instructions which asked to install vdsm/vdsm-cli and this is already done by ovirt-engine bootstrap. 1) uninstall vdsm and vdsm-cli - ovirt-engine will push down a vdsm package during the bootstrap process 2) disable selinux - edit /etc/sysconfig/selinux and set SELINUX=disabled - reboot 3) ensure ssl=false and fake_kvm_support=true in /etc/vdsm/vdsm.conf 4) restart vdsmd On the ovirt-engine instanes # we have a gateway in the way so we're using ssh tunneling to access # the ovirt-engine VM instance 1) re-install ovirt-engine and don't use localhost as the hostname since this value is passed to the host you install vdsm on and it will fail to push the bootstrap script down. This means that after you setup your tunnel, to get to the admin interface, you need to manually enter: http://localhost:8080/webadmin 2) edit /usr/share/ovirt-engine/engine.ear/components.war/vds/vds_bootstrap.py and comment out lines 836->839, like this. # if not oDeploy.virtExplorer(random_num): # logging.error('virtExplorer test failed') # return False 3) some misc stuff (not sure if it is needed, but looks harmless enough) mkdir /var/lock/ovirt-engine/ chown jboss-as:jboss-as -R /var/lock/ovirt-engine restorecon -Fvv /var/lock/ovirt-engine 4) update jboss configuration to not use ssl psql -U postgres engine -c "update vdc_options set option_value='false' where +option_name='UseSecureConnectionWithServers' and version='general';" 5) restart jboss service restart jboss-as > > Also, are their vdsm rpms built for RHEL6.x available?
