<para><emphasis role="bold">Host Operating System (Host)
:</emphasis></para>
<para>‘Host OS’ or ‘Host’ is commonly referred to the Operating
System installed on your hardware (Laptop/Desktop) and hosts the
virtual machines. In short, the machine on which your Virtual Box
is installed.</para>
<para><emphasis role="bold">Guest Operating System
(Guest):</emphasis></para>
<para>    ‘Guest OS’ or ‘Guest’ is commonly referred to the
Operating System installed on your Virtual Box Virtual Machine and
is an Virtual Instance independent of the host OS.</para>
<para><emphasis role="bold">Node :</emphasis></para>
<para>Node in this context is referring specifically to Servers.
Each OpenStack server is a node.</para>
<para><emphasis role="bold">Control Node:</emphasis></para>
<para>    Control Node hosts the Database, Keystone (Middleware) and
the servers for the scope of the current OpenStack deployment. It
is kind of like the ‘brains behind OpenStack’ and drives the
services like authentication, database etc.</para>
<para><emphasis role="bold">Compute Node:</emphasis></para>
<para>    Compute Node has the required Hypervisor (Qemu/KVM), and
is your Virtual Machine Host.</para>
<para><emphasis role="bold">Network Node:</emphasis></para>
<para>    Network Node provides Network as a Service and is
responsible for providing virtual networks for OpenStack.</para>
<para><guilabel>Using OpenSSH</guilabel></para>
<itemizedlist>
<listitem>
<para>Once you are done with setting up of network interfaces
file, you may switch over to SSH session by remote login into
the required server node (Control, Network, Compute) by using
OpenSSH Client.</para>

<title>Host Operating System (Host)</title>
<para>The operating system that is installed on your laptop or
desktop that hosts virtual machines. Commonly referred to as
<firstterm>host OS</firstterm> or <firstterm>host</firstterm>.
In short, the machine where your Virtual Box is
installed.</para>
</formalpara>
<formalpara>
<title>Guest Operating System (Guest)</title>
<para>The operating system that is installed on your Virtual Box
Virtual Machine. This virtual instance is independent of the
host OS. Commonly referred to as <firstterm>guest OS</firstterm>
or <firstterm>guest</firstterm>.</para>

<formalpara>
<title>Control Node</title>
<para>Hosts the database, Keystone (Middleware), and the servers
for the scope of the current OpenStack deployment. Acts as the
brains behind OpenStack and drives services such as
authentication, database, and so on.</para>

Machine host.</para>

<formalpara>
<title>Using OpenSSH</title>
<para>After you set up the network interfaces file, you can switch
to an SSH session by using an OpenSSH client to log in remotely
to the required server node (Control, Network, Compute). Open a
terminal on your host machine. Run the following command:
<screen><prompt>$</prompt> <userinput>ssh-keygen -t rsa</userinput></screen><screen><computeroutput>Generating public/private rsa key pair.
Enter file in which to save the key (/u/kim/.ssh/id_rsa): [RETURN]
Enter passphrase (empty for no passphrase): &lt;can be left empty>
Enter same passphrase again: &lt;can be left empty>
Your identification has been saved in /home/user/.ssh/id_rsa.
Your public key has been saved in /home/user/.ssh/id_rsa.pub.
