In a pilot environment running VMware Integrated OpenStack (VIO) v3.0, one of the ESXi management nodes experienced a network isolation event. As a result of the event, vSphere HA responded accordingly and began restarting the VMs on the isolated ESXi node onto other ESXi nodes. The isolated ESXi node happened to have the secondary VIO controller VM on it. When the VIO controller VM was restarted through vSphere HA on the new ESXi node, the operating system came online quickly. However, the vRealize Operations dashboard for OpenStack still reported the services in critical status.
