Hi, First, in order to understand the reason for bootstrap failures, please attach engine.log (ovirt-engine) and node logs (under /tmp/vds_bootstrap.log, vds_installer.log). Second, what you describe regarding the loss of network could derive from the following reasons: - host is configured with bonding - but bonding is not configured correctly. - NetworkManager interfere with networking config. - bridge (ovirtmgmt) is not set to with any BOOTPROTO or ONBOOT. Please attach network scripts (ifcfg-eth0, ifcfg-ovirtmgmt) and /var/log/messages .
