Different OS installing times for different infrastructures RRS feed

  • Question

  • Hi All,

    I have my dhcp, mdt, wds, dns server in a vmware workstation machine and it is configured on bridged network. My mdt works perfect, but I have observed the same OS same task sequences, gives lot of time differences on different infrastructures. I have hyperv server 2012 r2. When I created a vm and boot over network(same dhcp, mdt machine mentioned above), it takes 20-25 mins to deploy OS to that vm created in hyperv. I also have xenserver machine and when I create a new vm in xenserver 6.2, and I boot over network, it takes almost 45-50 mins to create vm. And if I create a new vm in my workstation and boot over network, it took almost 9 mins to complete OS installation. My mdt machine is same in all 3 cases. But still why there is so much lag in xenserver vms? Do i have to change anything to make it equal to 9 mins?

  • LTISysprep was just an example action, each action in the task sequence will have one more more lines in the log. Also, the logs you uploaded were not the completed ones. For the full logs, you need to get them from C:\Windows\Temp\DeploymentLogs.

    Anyway, they did contain enough info to be interesting, it's really the download and apply of the image that is different. Basically you can go back and yell at whoever setup the XenServer network or VM, because something is very wrong :)

    VMWare Workstation (emulating the Intel(R) 82574L Gigabit Network Connection NIC)
    Initial Gather and wizard launch: 43 seconds
    Partitioning of the disks: 9 seconds
    Downloading and applying the image: 10 minutes and 2 seconds

    The XenServer (emulating the Realtek RTL8139C+ Fast Ethernet NIC)
    Initial Gather and wizard launch: 33 seconds
    Partitioning of the disks: 6 seconds
    Downloading and applying the image: 41 minutes and 8 seconds

  • This is a question for a Citrix (xenserver) forum.

    But why would you use xenserver or vmware when you have hyper-v?

  • Hi,

    I have only one desktop machine with some good infrastructure like 16 gb ram, amd processor 1 tb storage etc.. so what ever I do, I have to use in that machine only. I have a seperate laptop with vmware workstation and I have my dhcp, dns, mdt etc.. so, on my desktop machine, I used hyperv for some months. when using with pvs, it gave me some problems and so I moved to xenserver. when using hyperv I used mdt, and with xenserver i used mdt. and I noticed that difference in os installing times. 

    I m not just pointing to xenserver in my question. If that is a prb, lets put xenserver to a side for a min.  If we take hyperv and vmware workstation, hyperv takes 20-25 mins where my workstation vm takes only 9 mins to install an os. Now any suggestions?

  • Put the two BDD.LOG files side-by-side, and see what actions are different in terms of time.

  • Hi,

    Thanks for the info, but bdd.log is difficult to understand.. do we have a simple way to check it? or do we a line which shows install time?

    How to find OS install time in bdd.log file?

  • Very easy, open the log in CMTrace (available in the free ConfigMgr 2012 R2 Toolkt), highlight the lines, in this example the from the Sysprep operation (LTISysprep), and you see the total elapsed time in the lower left hand corner. See this image.

  • Hi Johan,

    I have setup xenserver myself. I didnt change anything. Do I have to setup anything in network settings to make things faster?

  • Historical note for you young people out there.

    Fast Ethernet is *not* fast, it's slow. Gigabit is *Faster* than Fast Ethernet.

    Is the Realtek "Fast Ethernet" nic the fastest you can go? Do you have a Gigabit connection to the rest of your network devices?
