    Summary

    Not enough resources to failover a VM.

    Causes

    vSphere HA does not have sufficient resources to complete VM failover in a VMware vSphere Cluster. The problem can have the following causes:

    • Hosts in the cluster are disconnected, not responding or are placed to the maintenance mode.
    • Hosts have a vSphere HA error.
    • Some of VMs in the cluster have much more memory and CPU resources reserved than other VMs.
    • There are no free slots in the cluster.

    Resolution

    • Check hosts connectivity and state.
    • Re-configure VMs to balance resource reservation.
    • Make sure that there are free slots in the cluster.
