    I'm constantly having my Windows 11 VM "disappear" (The whole VM just stops/goes away).
    There's no error messages popping up. It doesn't feel like it's a Windows error as nothing occurs there - it's running and then the whole VM is gone.
    How do I try and diagnose what is happening here? Are their logs somewhere? Anyone else had this problem and found a fix?
    I'm running the latest Parallels and pretty close to the most recent Window 11 version.

    The crashes seem to be related to memory related. Mac OS is sending "[BALLOON] Memory pressure level changed: 0=>1" messages and then kills the VM.
    My system has 64GB total RAM - I've set my memory usage to 24GB in the VM, but when I look at Activity Monitor it's showing as 62.75GB - In Windows it thinks the system has 32GB in System Properties, but in the Task Manager it shows as 24GB.

    This appears to be a Parallels/macOS memory management issue rather than a Windows 11 crash. The log entry:

    [BALLOON] Memory pressure level changed: 0=>1

    indicates that macOS is experiencing memory pressure and may be terminating the VM process. Since Activity Monitor shows Parallels using nearly all available RAM, try reducing the VM's allocated memory (e.g., from 24 GB to 16 GB), reinstalling Parallels Tools, and reviewing Parallels logs for memory-related warnings. Also, check whether Automatic Memory Management is enabled and test with it disabled.

    My windows VM has been crashing several times a day for a few days. The VM is then in standby and I have to start the Vm from standby.
