What is OS Status?

Understanding the Compute Instance OS Status

What is the Compute Instance OS Status?

The Compute Instance OS status, also known as Guest OS Health, indicates whether the operating system is functioning correctly.

There are two possible OS statuses:

1. HEALTHY: The OS is functioning normally.

2. UNHEALTHY: The OS is currently unavailable or not responding.

You can view the instance's OS status in the following locations:

1. Compute Instance list page: It appears in the 'Status' column, displayed above the Compute Instance status.

1. Compute Instance detail page: It appears between the Compute Instance name and the Compute Instance status.

This status is displayed only if the instance has the QEMU agent installed.

If the QEMU agent is not yet installed on your Compute Instance, you can follow these instructions: How to Install the QEMU Agent.

Remarks:

1. Be cautious when selecting a source for launching a Compute Instance. If you configure the source settings to indicate that the QEMU agent is installed, but the source image itself does not actually have it, the OS status will permanently display as UNHEALTHY. Ensure this setting accurately reflects the source's configuration.

1. After launching a Compute Instance or performing certain actions, the OS may be temporarily unavailable. This can cause the OS status to briefly display as UNHEALTHY before returning to HEALTHY once the operation is complete. This is normal behavior.
