Disable balloon and sharing memory

We have a cluster with 5 5.1 ESXi hosts.  We want that there is no exchange of memory or the balloon.  We always made sure that our ESX host have a lot of RAM to accommodate what we attribute to our VM, so I think that we will take a performance hit if we were memory sharing/Exchange or swelling.

In our test group, I noticed that even though we have more memory on our hosts that requires the virtual machine, it seems there is sharing of some courses.  I wasn't able to well find it in our production environment.  I want to just make sure we subscribe all memory we ascribe to our guests and they are not exchanging around when not in use.

In the past, I found this option in the properties of the virtual machine on the 'resources' tab.  I think it's very good for CPU, a reservation is set to 0 but with unlimited box ticked.  For the record, I see 0 MB to as well, set of actions to normal, checked Unlimited.  I also see a checkbox for "reserve all the memory (everything locked).  I want to check this box to make sure there is no sharing?  I think that the balloon may be a different setting.

Hello

You can book all of the memory of the virtual computer and ESXi shares no memory of this virtual machine with an another VM.

But if you want to disable the balloon, you must do so within each VM guest operating system because VMware tools includes balloon pilot.

    Hi pillowgod,

    1. When did you start to question?

    2. you remember to make changes to the computer before this problem?

    You can check the following link and try to run the manual Intel WiFi diagnostic tool to check the functionality of your WiFi adapter.

    http://www.Intel.com/support/wireless/WLAN/sb/CS-025780.htm

    You can also try uninstalling and reinstalling the Intel wireless card and check.

    a. Click Start and type in Device Manager in the start search and press ENTER.

    b. expand the network adapters in the Device Manager

    c. right-click on the device, and then click Properties

    d. click on the driver tab and click on uninstall the drivers and click OK.

    e. restart the computer and check.

    You can also see the Intel Web site and try to download the latest version of the card wifi drivers.

  • ESXi Shared memory of commom and UCS B200M2

    I vSphere 4.x environment to IBM 3650 and half B200M2 (a group consisting of the 3650 and a group consisting of the B200M2).  IBM machines are 2 socket quad core with 34 GB of memory and Cisco are 2 Socket 6 core with 48 GB of memory.  Workloads on IBM and Cisco ESXi hosts are the same.  For most of 2008 and Windows 2003 machines.  On IBM machines, I move 1 GB, 2 GB of shared memory (common shared memory - amount of memory that is shared by all virtual machines powered and vSphere services on host machine) on each ESXi host.  On Cisco machines, I get around 15 MB on each ESXi host. Considering that it is one of the great features of VMware (sharing of memory) why is there such a huge disparity between the machines?  Is it because the Cisco blades NUMA machines?  Is there a setting I'm missing?  It's a huge difference.  I don't regret getting the UCS stuff I like it but it is the big novelty of the VMware that does not work with the UCS.

  • problems with dedicated and shared graphics memory

    So basically I want to run a game that I have all the specs (above actually) that I need to play outside of memory dedicated to the graphics card. But what confuses the life out of me, is that I have about double the necessary memory required in system memory shared which as I understand, it is used on an as-needed-basis. However, clearly this is not the case, as soon as I try and run it crashes immediately.

    Okay, so I have the graphics card with the following specifications:

    chip type: mobile intel (R) 4 series express chipsets
    channel of the card: mobile Intel GMA 4500 M
    total memory: 797 MB
    memory: 64 MB dedicated
    shared system memory: 733 mb

    In addition to what BossDweebe wrote, I would like to comment on your comment

    "I more than double the necessary memory required in system memory shared which as I understand, it is used on an as-needed-basis." However, clearly This is not the case, as soon as I try and run it crashes immediately. »

    Shared memory (part of your system RAM) is provided by Windows on a dynamic basis, it is added if required and with a limited amount by the RAM of the system itself needs to run applications (= your shared graphics memory size can be based on available RAM total). It's a help for some graphical features, but not necessarily a guarantee to run games that explicitly requires a certain base of dedicated RAM video. As the dedicated RAM (own GPU memory) is much faster than the share of the contributions of RAM, two cases can appear:

    (1) the game does not start. Many games check the video hardware before starting, and if they are 64 MB VRAM and require more, often it is game over. The dynamically allocated shared memory cannot be controlled and is of no interest here.

    (2) other games may be more forgiving. But you're going to be faced with a vicious circle: you're hoping using shared memory, is a clear indicator of a graphic solution already slow and Asthenique (i.e. an integrated graphics card). Unfortunately, the slow system RAM does not speed up your graphics card, and taking a part of the RAM for the graphics features: with a slower running your game and can still finish in the dysfunctions.

  • Premiere Pro, After Effects CS5 and the shared memory pool

    This feature works fine in Win 7 x 64. I think adding more RAM and going up to 12 GB. However, I noticed that CS5 sharing memory pool is limited to 75% of the physical RAM installed. Even if that makes sense, if you have a computer with the minimum requirements of 4 GB (because Windows itself will use a little less 1 GB + /), it makes less sense to 12 GB, where 9 GB is all you can use for the pool of CS5.

    Is this the way it works, or is it possible that I can be 'greedy' and go the number of 75% for larger amounts of physical RAM? It helps to have as physical RAM as much as possible for AE previews high resolution, etc..

    It is by design.

  • Satellite Pro C660 - 21 d - how to change the shared memory graphic value?

    My dxdiag screen says I have almost 1700 MB of video memory, but when I try to use this memory on games these games can use 256 MB...

    I tried to change settings in the BIOS, but it does not have this setting, do not know what else could cause this problem?

    Hello

    This could be confusing, but this isn't a problem.
    Shared memory is controlled by the graphics driver and the driver affects the part of the main memory to the memory of the graphics card ONLY if its required by a running application.

    The Dxdiag shows you how much RAM could be shared and value of memory in the quizzes you shared memory which is used and who is in the game right now.

  • Satellite A300D-126 - how to set shared memory?

    Hello!

    A month ago I bought 4 GB of RAM (2x2gb) and I got Windows 7 as operating system.
    My RAM memory is automatically extended to my grafic card (from 256 to more than 1,500 then) and everything worked fine...

    As I could not find the driver for the camera for Win 7, I decided to go back to Win XP and so I did.
    Now, my graphics card is 256 MB and memory system 3.25 GB of RAM. All my drivers are up to date.
    I don't know how to set up shared memory...

    In the BIOS there is no option for it, and I can't update the BIOS when I download the new version...

    Please give me an idea to try out! ... TNX!

    Hello!

    The reason why you can use the entire 4 GB of RAM of the t is the reason why you are using Windows XP or let's say a 32 bit OS. On 32 bit OS it is limitation of memory and so t may be used more than 3.25 GB of RAM. If you want to learn more about this limitation please read this article:
    http://APS2.toshiba-tro.de/KB0/TSB82022E0000R01.htm

    Furthermore there is no BIOS option to set the graphics memory. It also depends on the limit of 4 GB and the size of the graphic RAM will solve automatically.

    Hello

    I am a happy owner of this laptop great and I added an extra RAM to consider to 8 GB.

    All data sheets on the State of sites detailing the gpu that can be assigned up to 1.7 GB of memory share.

    Previous experience from other computers is that this amount of memory is impaired in the BIOS settings, but I don't see any option in the latest BIOS 1.60.

    Obviously theres a lot of RAM to give to the GPU, but I do not see how to assign. The i5 chips allocate dynamically once Windows is running or the BIOS is missing this setting?
