The license key is intended only for use with Plesk operating inside the following virtual environments

1. Use the following script, both Linux and Windows. Create a file with the following code (named as info.php):

   CONFIG_TEXT: <?php
   require_once('api-common/cu.php');
   cu::initCLI();
   $cu = new cu();
   try {
   $si = var_export(getServerInfo(), true);
   cu::print_stdout($si);
   
   } catch(Exception $e) {
   cu::print_stderr("Error: " . $e->getMessage());
   cu::cuExit(1);
   }
   
   cu::cuExit(0);

2. Then execute it:

   • Windows:

     C:\>"%plesk_bin%\php.exe" info.php | findstr platform

   • Linux:

     # /usr/local/psa/bin/sw-engine-pleskrun info.php | grep platform

3. On a screen you will see a result of Plesk detection:

   • dedicated or none stands for physical hardware.
   • If parallels-server is shown, run systeminfo command to get BIOS Version: Parallels Software International Inc. 6.11.25122.123124 stands for Virtuozzo version 6, update 11.

execute the following command:

• Windows:

  C:\>"%plesk_bin%\php.exe" -dauto_prepend_file= -r "echo get_virtualization();"

• Linux:

  # /usr/local/psa/bin/sw-engine-pleskrun -dauto_prepend_file= -r "echo get_virtualization();"

• On Linux, other utilities you can use (not related to Plesk) include dmidecode and lspci .

• Additionally, on Windows, the following steps may be followed to get BIOS information:

  • Run wbemtest in the command line.

  • Click Connect twice.

  • Click Query.

  • Execute:

    mysql> SELECT * FROM Win32_BIOS

    If this results in BIOS information similar to Version='ACRSYS - 1', the BIOS was hacked and the hack should be deactivated, or the license for Dedicated servers needs to be obtained.

    If the output suggests the lack of a virtual platform, there is no other way to make Plesk detect it other than to re-deploy it properly with the correct settings.

• Make sure that Plesk Management Service is up and running. Restart Plesk management services:

  • Windows:

    Login into server as Administrator Start menu > All programs > 'plesk services monitor' > Restart 'Plesk Management Services'

  • Linux:

    # /etc/init.d/psa stop $ /etc/init.d/psa start

• Confirm it using below command on the server:

  C:\> "%plesk_bin%\php.exe" -dauto_prepend_file= -r "echo get_virtualization();"
