Clone an Instance

Overview

Cloning creates an exact copy of an existing instance — including its root disk, attached volumes, network configuration, security groups, and key pair. The clone can optionally be placed on a different network or availability zone. This is useful for scaling horizontally, creating test environments from production instances, or duplicating pre-configured application stacks.

Xloud-Developed — Instance cloning is developed by Xloud and ships with XAVS / XPCI.

Prerequisites

An instance in Active, Stopped, or Shutoff status
Sufficient quota for the new instance (vCPU, RAM, disk)

Clone an Instance

Dashboard
CLI

Open the Clone dialog

Navigate to Compute > Instances. Click the More dropdown on the instance row, then select Clone Instance under the Clone & Template group.

Clone Instance is only available for instances in Active, Stopped, or Shutoff status.

Configure the clone

Field	Type	Required	Default	Description
Instance	Read-only	—	Source name	The instance being cloned
Name	Text	Yes	`{source}-clone`	Display name for the cloned instance
Network	Dropdown	No	Same as source	Optionally place on a different network
Available Zone	Dropdown	No	Same as source	Optionally place in a different zone
Auto Start	Checkbox	No	Checked	Start the clone automatically after creation
Description	Text area	No	—	Optional notes

Leave Network and Available Zone empty to use the same settings as the source instance. Override them only when you need the clone on a different network segment or fault domain.

Create the clone

Click Confirm. The clone appears in the instance list with status Build, transitioning to Active when ready (if Auto Start is checked).

Cloned instance is Active with the same configuration as the source.

Source credentials

source openrc.sh

Clone uses the Xloud-developed Nova API extension:

Clone an instance

curl -X POST -H "X-Auth-Token: $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "xloud-clone": {
      "name": "my-instance-clone",
      "auto_start": true
    }
  }' \
  "$NOVA_ENDPOINT/v2.1/servers/<INSTANCE_ID>/action"

Clone to a different network

curl -X POST -H "X-Auth-Token: $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "xloud-clone": {
      "name": "my-instance-clone",
      "auto_start": true,
      "network_id": "<TARGET_NETWORK_ID>",
      "availability_zone": "az2"
    }
  }' \
  "$NOVA_ENDPOINT/v2.1/servers/<INSTANCE_ID>/action"

Clone uses the Xloud-developed xloud-clone Nova server action. The standard openstack CLI does not have a native clone command.
