<para>The OpenStack Compute service is a cloud computing fabric
|
|
controller, which is the main part of an IaaS system. You can use
|
|
OpenStack Compute to host and manage cloud computing systems. This
|
|
section describes the OpenStack Compute configuration
|
|
options.</para>
|
|
<para>To configure your Compute installation, you must define
|
|
configuration options in these files:</para>
|

<itemizedlist>
|

<listitem>
|

<para><filename>nova.conf</filename>. Contains most of the

Compute configuration options. Resides in the

<filename>/etc/nova</filename> directory.</para>

<para>You can use <filename>nova.conf</filename> file to configure

where Compute logs events, the level of logging, and log

|
formats.</para>
|
|
<para>To customize log formats for OpenStack Compute, use the

configuration option settings documented in

<title>Configure authentication and authorization</title>
|

<para>There are different methods of authentication for the
|
|
OpenStack Compute project, including no authentication. The
|
|
preferred system is the OpenStack Identity service, code-named
|

Keystone.</para>

<para>To customize authorization settings for Compute, use the

configuration options documented in

<xref linkend="config_table_nova_authentication"/>.</para>

<para>To customize certificate authority settings for Compute, use the

<title>Configure resize</title>
|
|
<para>Resize (or Server resize) is the ability to change the
|
|
flavor of a server, thus allowing it to upscale or downscale
|
|
according to user needs. For this feature to work properly, you
|
|
might need to configure some underlying virt layers.</para>
|
|
<section xml:id="kvm-resize">
|
|
<title>KVM</title>
|
|
<para>Resize on KVM is implemented currently by transferring the
|
|
images between compute nodes over ssh. For KVM you need
|
|
hostnames to resolve properly and passwordless ssh access
|
|
between your compute hosts. Direct access from one compute
|
|
host to another is needed to copy the VM file across.</para>
|
|
<para>Cloud end users can find out how to resize a server by
|
|
reading the <link
|
|
xlink:href="http://docs.openstack.org/user-guide/cli_change_the_size_of_your_server.html"
|

>OpenStack End User Guide</link>.</para>

<section xml:id="xenserver-resize">
|
|
<title>XenServer</title>
|
|
<para>To get resize to work with XenServer (and XCP), you need
|
|
to establish a root trust between all hypervisor nodes and
|
|
provide an /image mount point to your hypervisors dom0.</para>
