NotEnoughResourcesToStartVmEvent

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.
