Doc Type: Bug Fix
Doc Text:
Due to a bug in VDSM, ifcfg files that served multiple networks sometimes contained ONBOOT=no, and as a consequence, rendered management networks (or other important networks) unavailable during the early stages of boot. As a part of another change, all ifcfg files are now ONBOOT=yes, thus solving this bug, and making this scenario impossible. All networks are now loaded by network service and are not flushed later by VDSM, except in cases where the VDSM service recognizes them as different from the persistent network configuration.
