  • providing a VIF manager instance on each node of a cluster, wherein one of the VIF managers is designated as coordinator;

    providing a set of VIF failover rules for all VIFs in the cluster to each VIF manager via a replication database (RDB) service;

    using a single read-write (RW) transaction of the RDB service by the coordinator to publish revised VIF hosting assignments pursuant to the VIF failover rules in response to a VIF failure; and

    hosting, by each VIF manager of each node affected by the published revised VIF hosting assignments, VIFs pursuant to the published revised VIF hosting assignments without performing additional RW transactions by any VIF manager in the cluster.
