Cannot create an OCI Compute Instance: InternalError - Out Of Host Capacity

When an instance is created by using an API call or from the Oracle Cloud Infrastructure (OCI) console, this error message is displayed: “InternalError. Out of host capacity.”

The issue occurs because the selected shape does not have any available servers in the selected region and Availability Domain (AD).

Virtual Machines (VM) are dynamically provisioned. If an AD reaches a minimum threshold, then new hypervisors (physical servers) are automatically provisioned.

There may be some occasions where the additional capacity has not finished provisioning before the existing capacity is exhausted; but when retried after 15 minutes, the required shape may become available.

Alternatively, selecting a different shape, AD, or region will almost certainly have the required capacity. We can try new region and it will be successful.
