<para>FIXME</para> <para>After you've configured the Compute service, you
can now launch an instance. An instance is a virtual machine provisioned by
OpenStack on one of the Compute servers. Use the procedure below to launch a
low-resource instance using an image you've already downloaded.</para>

<title>Launch a Compute instance</title>
<step><para>Generate a keypair consisting of a private key and a public key to be able to launch instances
on OpenStack. These keys are injected into the instances to make
password-less SSH access to the instance. This depends on the way the
necessary tools are bundled into the images. For more details, see
"Manage instances" in the
