1504                         <para>This section describes the installation of Evergreen software in so-called "virtualized"
1505                         software environments. Evergreen software runs as a native application on any of several
1506                         well-known x86 (32-bit) and x86-64 (64-bit) <systemitem class="osname">Linux</systemitem>
1507                         distributions including <systemitem class="osname">Ubuntu</systemitem> and 
1508                         <systemitem class="osname">Debian</systemitem> but it does not run as a native application 
1509                         on the <systemitem class="osname">Microsoft Windows</systemitem> operating system. 
1510                         However, it is possible to execute Evergreen on a <systemitem class="osname">Windows</systemitem> 
1511                         host system by running it within a virtual Linux-guest installation, which itself executes 
1512                         on the <systemitem class="osname">Windows</systemitem> system. 
1513                         The <systemitem class="osname">Linux</systemitem> environment is fully emulated and acts 
1514                         (within limits) just as if it were executing on a real standalone system.</para>

1518                         <systemitem class="osname">Linux</systemitem> host for Evergreen. This architecture is not
1519                         recommended for large scale systems since there are performance limitations to running Evergreen
1520                         in a virtualized environment. However, it is a reasonable architecture for smaller experimental
1521                         systems, as a proof of concept, or as a conference-room pilot.</para>
