    Just got a new Penryn Macbook Pro, running 10.5.2 + all updates.
    Got 4 gb of memory specifically to run virtual machines comfortably, but
    now I keep getting errors on allocating memory.
    Build 5584. Machine name is blahblah.

    Error is:
    Apr 1 13:45:20 blahblah kernel[0]: [err in mmIo4gbCacheAllocB] : Failed to allocate page from 4gb cache -> ../host.Darwin/mm/io_memory.cpp:342
    Apr 1 13:45:22 blahblah kernel[0]: [err in vtxSwitchOnCallbac] : VMXON failed (0x1, 0xffffffff_83542000, 0xd). -> vtx.c:468
    Apr 1 13:45:22 blahblah kernel[0]: [err in vtxSwitchOnCallbac] : VMXON failed (0x1, 0xffffffff_bc081000, 0xd). -> vtx.c:468
    Apr 1 13:45:36 blahblah /usr/sbin/spindump[2961]: process 2956 is being monitored

    I see that this is a problem others are reporting. Idea of when it will be resolved?
    I bet a number of people got more memory to make things work better, not worse.

    past experience is that small is beautiful

    my WinXp VM works well with 924 mb
    but a 32g hardedisk only 20% full
    allowing plenty of room for invisible temporary files

    which OS in VM?

    512 mb, WinXP pro
    Doesn't always happen. If I start up parallels soon enough after rebooting,
    it will make it. If I run for a while, it can't allocate it.

    I have a MacBookPro 2.6 Ghz core 2 duo with 4Gb 667 MHz DDR2 SDRAM running OS 10.5.2 and windows XP Pro as the guest. It worked great for three months. this morning after an apple update I got the


    Parallels Desktop failed to allocate the specified amount of memory.
    Please restart Parallels Desktop and try again.
    To avoid this problem in the future choose from the menu: Parallels Desktop > Preferences. On the Memory tab select the "Enable virtual memory preallocation" option.

    The above advice did no good.

    Rebooting did no good.

    This thread indicates a long standing problem

    Any solution or is this a fatal flaw with Parallels?

    this is one of the reasons I still run OS 10.4.11
    since OS 5 or 6 or so Apple updates tend to break exisiting software
    if a widespread BUG Parallels team will fix it ASP as they did when an apple update broke the shared clipboard

    Hi,

    same on my side with a MPB 15" / 2,4 GHz / Santa Rosa / 4GB-Ram:

    I run a VM with XP with 768 MB of RAM, it works very well.
    Raising the RAM to more than 1 GB didnt show any effect, I was a little disappointed .... well.

    Also raising the graphics memory from 16MB to 64 MB didnt make the GUI more "fluid"... (in coherence mode)
