10         <para>Installing, configuring and testing the Evergreen server-side software is straightforward with the current stable software release. See

12                 operating system.</para>
13         <para>The current version of the Evergreen server-side software runs as a native application on any of several well-known <systemitem class="osname">Linux</systemitem> 
14                 distributions (e.g., <systemitem class="osname">Ubuntu</systemitem> and <systemitem class="osname">Debian</systemitem>). It does not currently run as a native application 
15                 on the <systemitem class="osname">Microsoft Windows</systemitem> operating system (e.g., <systemitem class="osname">WindowsXP</systemitem>, 
16                 <systemitem class="osname">WindowsXP Professional</systemitem>, <systemitem class="osname">Windows7</systemitem>), but the software can still be installed and run on 
17                 <systemitem class="osname">Windows</systemitem> via a so-called <emphasis>virtualized</emphasis> Linux-guest Operating System (using, for example, 
18                 <application>"VirtualBox"</application>, or <application>"VMware"</application>, or <application>"VirtualPC"</application> to emulate a 
19                 <systemitem class="osname">Linux</systemitem> environment). It can also be installed to run on other <systemitem class="osname">Linux</systemitem> systems via virtualized 
20                 environments (using, for example, <application>"VirtualBox"</application> or <application>"VMware"</application>). More information on virtualized environments can be 
21                 found in <xref linkend="serversideinstallation-virtual"/>.</para>

1311                                         <para>At this point, the <systemitem class="osname">Windows</systemitem> system is hosting an <systemitem class="osname">Ubuntu</systemitem> system, which itself is hosting the Evergreen distribution. So far as Evergreen is concerned, it is happily executing in a standard <systemitem class="osname">Ubuntu</systemitem> environment and behaves exactly as if it were executing on a standalone <systemitem class="osname">Ubuntu</systemitem> system.</para>
1312                                         <para>Of course, there are limitations to how well a virtualized <systemitem class="osname">Ubuntu</systemitem> system emulates a real one. The <application>"VirtualBox"</application> application itself consumes memory, and it contributes to the CPU load on the <systemitem class="osname">Windows</systemitem> host system. The emulated <systemitem class="osname">Ubuntu</systemitem> system will have less available memory and will execute more slowly than if it were a standalone system, therefore Evergreen itself will inherit some limitations from this overall environment.</para>
1313                                         <para>However, this technique of using a <systemitem class="osname">Windows</systemitem> host to emulate a <systemitem class="osname">Linux</systemitem> environment is a practical way to install and run an Evergreen system even if it isn't possible to dedicate a real machine solely as a <systemitem class="osname">Linux</systemitem> host for testing. This is a reasonable architecture for simple experiments, or as a proof of concept, or as a conference-room pilot.</para>
