windosw 7 vm locks up when browsing to main computer / network drive RRS feed

  • Question

  • I installed a Windows 7 32 bit VM on my Windows 7 64 bit OS.

    I have Integration features enabled

    I can browse to my DVD drive ... but when I try to run a setup.exe (to install a program) it locks up

    In fact even if I browse to my main computer and try to run a program ... it locks up

    ?? is there some setting I'm missing (or need to set)?

    I have turned UAC OFF

  • I'm wondering if there might be a NIC driver/TCP
    Offloading problem that might be causing the disconnects.  I've seen
    similar problems.
     
    It might be worth a try:
     
    Use at your own risk and only if you are comfortable with editing the
    registry!
     
    To turn off TCP Offloading, add a DWORD value in
     
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Tcpip\Parameters
     
    label it  DisableTaskOffload , and change the value to 1, then reboot.
     
    This basically turns of the NIC's ability to do some of the network
    processing and so the CPU has to do it, but unless it's a very high
    usage NIC, it shouldn't make much difference to the user.

  • Now that I am past accessing the network .... the VM seems unusable

    Almost anything I try to do requires 100% of CPU which results in non-resposiveness

    example trying to run MS Visual Studio 2010 ... task manager is flashing CPU at 100% ... I have 3 GIG of memory allocated for thiw VM ... I can't believe that it cannot run anything!

    Is this another known issue? I'm using Windows Virtual Machine ....

    I'm thinking of switching to VM Ware? this just seems pointless ... if it's unusable.

  • How much memory on the host?  My guess is that you are starving the host
    for resources, cut the memory allocated down to 1G or 2G, and see how it
    runs in each configuration.
     
    Are you running Windows VPC, or VPC 2007?
     
    If that doesn't help, VMWare player might do you.  It probably will run
    Windows 7 a bit better in a VM, but at the expense of programs running
    on the host.  If that's not a concern, then it should work.  VirtualBox
    is another virtualization solution that can work pretty fast if its
    compatible with your hardware.

  • I have 16 gig total (host computer); quad core

    I allocated 2048MB to the XP Mode (VM) which works ok

    I allocated 2560MB to the Windows 7 VM

    The task manager on the host shows the CPU at 30% when the VM CPU is at 100%
