    If you want all vm's to be able to share things like ethernet (instead of nat) or Dvd or... dare I say... video card, you need it. Otherwise you assign it to the active vm manually.

    Doesn't vt-d allow the vm hardware level access? Would you be using the vm to set up a network and have the host os sit behind it?
    Vt-d passes the link over the host os and doesn't share, unless I'm missing a hidden feature.

    Right. For more self-reading see Thrawn's response:
    http://forums.whirlpool.net.au/archive/1818049


    Basically 1 and only 1 host can use an I/o resource at a time at hw level without vt-d (excluding Cpu/ram) networking gets around this by nating to each vm on the same host os resource. Vt-d actually allows true virtualization of I/o. Since most run workstations to switch between os's using one at a time, manually re-assigning an I/o resource (or having a nated connection for ethernet) is fine. I will be having virtual machines that need simultaneous access to I/o and true virtualized peripherals.

    I am going to run virtualized networking appliances for demonstration to customers, so software layers between the guest os and I/o (affecting performance) is not the best. I agree, my needs represent a bit of a corner-case, but I actually got this 9150 for that purpose (the gaming prowice is a bonus).

    More:
    Intel’s hardware assist for virtualization helps to lower the overhead of virtualization software. Intel VT (introduced first in 2005) today represents a platform centric innovation in hardware assist encompassing Intel VT-x in the processor, Intel VT for Directed I/O (VT-d) for I/O virtualization in chipset and Intel VT for Connectivity (VT-c) in the networking devices, all of which help VMs reduce the virtualization software overhead across the platform and increase the performance.

    Has anyone experienced keys not registering on this laptop? Like you really have to pound on the keyboard to get things to register accurately?

    Just got this laptop and having this problem.

    I really hope that some of the keyboard problems that people are experiencing are the result of rushed work by Sager.

    All game related issues w/ the 7970m are due to drivers; it can definitely play those games maxed out; except BF3 you might have to turn down shadows and AA. Just use SMAA or FXAA injector; you will easily gain another 10fps lol.
