Provisioning Services Boot Process Diagram

Citrix just released a pretty useful Info Poster Diagram on the PVS Boot process.  Here’s a quick summary taken from the poster :


The following summarizes the PVS Boot Process detailed on the diagram :

  1. IP Acquisition – The Target Device acquires an IP address.
  2. Bootstrap Download – The bootstrap file is downloaded.
  3. PVS Logon Process – The Target Device logs on to PVS.
  4. Single Read Mode – Single read mode communication is established between the Target Device and the PVS Server.
  5. BNISTACK / MIO – The BNISTACK driver on the Target Device takes over communications with the PVS Server and Multiple I/O occurs.

Application Launch Requests Might Fail on a Provisioned XenApp Version 6.0 or 6.5 Multihomed Server



Application Launch Requests Might Fail on a Provisioned XenApp Version 6.0 or 6.5 Multihomed Server.

Pour faire simple... Si vous rencontrez une erreur lors du lancement d'une application publiée. Rendez-vous dans le APP-CENTER et regardez si dans les informations du SERVEUR  vous voyez l'IP de votre serveur de publication.

Ce n'est pas le cas. Donc vous avez des serveurs de publication XenApp 6 ou 6.5 en multi-homed...... Cette CTX et ce petit article est pour vous.

Petit détail, un simple redémarrage du service IMA n'a pas suffit dans mon cas j'ai été obligé de sortir les serveurs de la ferme et de les intégrer à nouveau.

Place à la résolution maintenant .......

Resolution :

You can resolve this issue by completing the following procedure:

    At a command prompt, type the following command , and then press Enter:
    set devmgr_show_nonpresent_devices=1

    Type the following command at command prompt, and then press Enter:
    start devmgmt.msc

    Troubleshoot the devices and drivers in Device Manager.

    Note: Click Show hidden devices on the View menu in Device Manager before you can see devices that are not connected to the computer.

    You will see Ghosted NIC cards under network adapters, as shown in the following screen shot:

    Right-click and delete the Ghosted Ethernet Adapter(s)
    Note: Ensure not to delete non-ghosted adapters.

    Restart the IMA service.

Now you will see only one correct Network Adapters IP address in the Citrix AppCenter.

    You should now be able to start your application successfully.

XenDesktop Planning Guide: Provisioning Service Networking

CITRIX RELEASE : Provisioning Service Networking GUIDE :

Citrix Provisioning Services (PVS) is a software streaming technology that allows servers and desktops to be provisioned and re-provisioned in real time from a single shared-disk image. The service is commonly integrated within a Citrix XenDesktop architecture to deliver virtual desktops efficiently.

One of the many benefits of PVS is the ability to scale, however when called upon to delivery high volumes PVS servers have significant network requirements. Therefore when planning the implementation of PVS it is important to take these requirements into consideration.

This planning guide provides Provisioning Services networking guidelines. It provides best practices, and recommendations to consider when planning to deploy PVS. It is not intended as a comprehensive guide for planning and configuring network infrastructures, nor as a networking training handbook.

The guide assumes the reader has knowledge of PVS, servers are running Windows Server 2008 R2, and clients have 1 Gigabit interfaces.
