    initial v1  
    33I am running a Windows 7 x64 Guest VM and also have a guest clock that is running extremely slow.  The guest is in sync for about 20 minutes then gets to almost 5 minutes out of sync, before syncing again (trying w32tm /resync via the Task Scheduler), or needs to be manually resync'd since it never gets to the next time to resync.  The applications I need to run are very time sensitive (i.e. decorating incoming frames from a video source), and require quite a bit of CPU.  The VM has approximately 4 cores at 2.53GHz, and 8 GB RAM allocated.  The Host has a total of 24 cores, and 48 GB RAM, and this is the only VM.  However, the host is also running some cpu, and RAM semi-intensive software.
