    I would be interested to know if any of you guys have tested Windows Server 2012 under vSMP foundation(using KVM). would this incur in too much inter processor communication latency? or would Wine would be best suited? remember wine cant run some windows only app and virtualization is need it

    This is definitely a possibility, if you are looking for larger memory capacity for WS2012. Please note that we however noticed that CPU scalability is not so great.

    Wow, I still cant believe I am getting help from Shai fultheim himself, you are my Hero, you have done what other just dream about….

    the not so great CPU scalability is Outweigh by the sheer amount of cores you could throw at the problem..

    Question, is the CPU Scalability only on Windows Server OS? I would think Linux server Oriented nature would shine in Large SMP like system created by vSMP, using Wine would have to do for now I guess.

    if you application needs high core count the KVM VM will need to have high core count. We have not seen WS2012 scaling if the number of cores used by single KVM VM used for WS2012 exceed cores of one node.
    On the other hand, if you just require large memory for your VM (WS2012), or if you are looking to scale up number of cores used by Linux than we have a pretty good solution for you.
