Over-committing of Coefficients

This feature is available only in DaDesktop Private Server (DDPS) and DaDesktop On-Premise (DDOP).

 

With the growing complexity and processing demands of courses—especially those using nested virtualization or high-performance requirements for many trainee desktops—you might occasionally see an error like this :

This warning appears for CPU, memory, or disk space limitations. Your first step should be to try moving your machine(s) to a less heavily loaded server or data centre, or to reduce resource requirements wherever possible.

If neither option is feasible and your running units are just slightly above the maximum normally allowed, you can temporarily use 'over-committing' for the CPU, memory, or disk coefficients. This can be done in the GUI as shown below.

Navigate to /da/admin/servers/all, click the Edit button for your server, then scroll down to this section.

The server list also displays servers using over-committed coefficients. This is handy when you need to revert these settings after a course ends, resetting the coefficients to their defaults.

 

 

 

 

 

 

 

 

 

 

Any modifications should be considered a temporary fix, not a permanent solution to resource shortages. Changes that allow a course to run should be reverted once the course is finished.
 

DaDesktop On-premise Requirements

The over-committing feature is possible thanks to tpapi which is part of the DaDesktop codebase. Tpapi currently only supports Python 3.12, so the host operating system needs at least Ubuntu 23.10.
