When you create a new cloud server, you can attach an isolated network
to it. You can also attach an isolated network to an existing server by
using one of the following methods:
- By using the Cloud Networks API
- By creating an image of the server and building a new server based
on that image in the Cloud Control Panel
If you use the Cloud Networks API to attach network interfaces to or
detach them from a cloud server, you might experience a brief
interruption (lasting 3-4 seconds) in traffic hitting your cloud
server while the system resets networking on the server.
Warning: For servers running Rackconnect v2.0, do not attach or
detach a cloud network to or from the server. Attaching or detaching
a cloud network, in this case, causes the system to reset the network
stack, which breaks the cloud server's connectivity to Rackconnect
v2.0. If you need to attach a network to a cloud server that currently
runs Rackconnect v2.0, contact support before making the change.
To attach an isolated network to an existing cloud server by cloning it
in the Cloud Control Panel, perform the following steps:
Log in to the Cloud Control Panel.
In the Cloud Servers list, click the server to which you want to
attach the isolated network.
On the Server Details page, scroll to the Images section.
If you already have an image for this server, skip to step 5.
To create an image for the server, in the Details page of the
server in the Images section, click Create Image, enter a
name for the image, and then click Create Image.
It might take a few minutes to create the image.
In the Images section, click View Images.
Next to the image you want to use, click the gear icon and then
select Create Server with Image.
On the Create Server page, enter the name of the new server. The
image is preselected for you.
Select a size, or flavor, or the server.
Expand the Advanced Options section and click Select Networks.
Select an existing isolated network in the pop-up dialog box, or
click Create Network to create a new one. If you are creating a
network, enter a network name and then click Create Network.
Note: The system automatically attaches all new servers to the
PublicNet (the Internet) and ServiceNet (the Rackspace data center
network) networks. Before removing these networks from the server,
we strongly recommend that you read
Removing Networks from a Cloud Server
to fully understand the limitations on this server if you remove
Click Create Server.
The preceding steps create a new server with new public and private IP
addresses and attach it to your selected networks.
