Abstract: A virtual desktop system includes a user system, a system manager, and a virtualization host including a processor and a performance module. The performance module is operable to receive a first data packet, determine that the first data packet is associated with the user system, and add a label to the first data packet, the label being operable to provide performance information for the virtual desktop system. The user system is operable to receive the first data packet and extract the performance information from the label. The system manager is operable to receive the performance information from the user system.
