# Unable to Create Virtualized Cluster

## Problem

You may run into an error when trying to create a new virtualized cluster that informs you that cluster creation failed because one or more of the Private Cloud Director services are not healthy. The error message might at times say "Hypervisor services are not ready"

## Environment

* Private Cloud Director Virtualization - v2025.6 and Higher
* Self-Hosted Private Cloud Director Virtualization - v2025.4 and Higher

## Cause

The most common case of this is when you attempt to create a new virtualized cluster **immediately after making updates to your cluster blueprint**. Changes to cluster blueprint may require a service restart of compute and / or networking service. If the service is being restarted, the service status health API will report the service to be unhealthy, which will result in this error when creating a cluster.

Note however that you may also run into this error because the one or more of Private Cloud Director services are currently experiencing an issue or an outage.

## Diagnostics

Refer to the service health dashboard for details on which services may currently be unhealthy.

## Resolution

Refer to the debugging documentation for the individual service to identify the problem if any.

Once all the services are healthy, retry the operation.
