I concur that it happens only in Unity. I also have multiple screens - one 30" surrounded by 2 21" screens in portrait mode on a separate graphics card. This exceeds the maximum hardware-accelerated texture size, and VMWare Fusion should therefore be using software rendering... but I have turned off "Use all displays in fullscreen" and it seems happy to use what seems to be full speed on the central display in fullscreen mode.

I upgraded to 2.02, and turned off all folder sharing and mirrored folders completely, and also deactivated "allow your mac to open applications in the virtual machine", and switched back to Unity.

The vmwareuser.exe 100% CPU problem has not happened to me in the six or so hours of use I've had since then, whereas it used to happen after about fifteen minutes of Unity usage (I'd given up on Unity as a consequence). It's early days yet, but something appears to have at least improved, if not been fixed properly.

Thanks for feedback. I guess maybe VMwareUser inside the
guest un-registered all callbacks. Can you follow the instruction to
collect guest log?

To do that go to:
C:\Documents and Settings\All Users\Application Data\VMware\VMware Tools, Then open the tools.conf file.

Add two entries:
log = "TRUE"
log.file = "C:\vmtools.log"

Then log out and log back in to your VM Wait for vmwareuser.exe to start using 100% of your cpu and upload the resulting log
files. There should be one at c:\vmtools.log and possibly more than one
at c:\vmtools.log.<process id> where process id is just a number.

Once you are done, make sure to turn off logging by removing the two entries because they can take up a lot of space over time.

I've tried what the last poster suggested and it doesn't fix the problem for me when in Unity on a dual screen iMac.

And, I don't have a C:\Documents
and Settings\All Users\Application Data\VMware\VMware Tools folder
within my VM and therefore don't have a tools.conf file to open. (ignore this, found it, t'was hidden!)

Further information if anyone is still listening....

This problem only seems to occur for me when I run Unity with Shared Folders and when I drag n drop a file from Mac to a shared folder. Using shared folders in full screen mode works fine.

I have now stopped using shared folders and am now accessing an AirDisk from Mac and Windows in order to share files. So far (fingers crossed) this setup has now stopped the 100% CPU annoyance.

Logs have been emailed.

I screen grab in Leopard using CMD+SHIFT+4 which creates a file on the desktop. I then drag that file into the shared folder within Mac which has a link in my dock (ie. I've put 'Shared Folder' which is in my Documents on Mac side in my dock - I then drag the file from the desktop onto 'Shared Folder' on the dock - this seems to trigger the 100% CPU). I can then access that shared folder from within Windows to use the screen grab.

I hope that makes more sense.

I think it does it for all files, it's just I do screen grabs quite a bit.

1. It is the VMwareUser.exe that takes 100% of CPU.

2. Yes, I don't have a problem when in full screen mode, only when running Unity on my dual screen iMac.

3. In Finder on the Mac I created a folder within my Documents folder called 'SharedFolder' (so /Users/xxxx/Documents/SharedFolder) I then share this folder 'SharedFolder' from my Mac with the Virtual Machine on the Sharing tab of the VM Settings. I DO NOT mirror any folders at all.

In Finder on the Mac I drag my 'SharedFolder' to my dock so I have easy access to it. I can then drag n drop any files I want to see within Windows to my 'SharedFolder' in my Macs doc.

One thing which may affect it??? I have the Windows taskbar on my external screen when running in Unity and my dock on my iMac screen - not sure if that would make any difference.

Also, I just tried to re-create the problem again and it looks like I also have to open Internet Explorer and have that on the iMac screen too in order for the 100% CPU.

So, iMac screen plus external screen - Windows in Unity mode running with taskbar on external screen - Mac dock on iMac screen. Open IE7 and move that to iMac screen - drag n drop a file into SharedFolder in the dock then 100%CPU issue occurs!

Can I just add that Shared Folders isn't the only cause of the problem.

I have been running for about 4 hours today with Shared Folders switched off and the 100% CPU has just surfaced again!

I am now going to try using Unity with the 'Show running virtual machine applications in the Dock' set to Never (it was set to In Unity this morning when the problem happened).

How about fixing SR# 1139197970? You acknowledged that it was a real bug. It pins my cpu to 100% if I turn on my Cisco VPN. Yet this has not been fixed, and it is not listed on the latest release notes "known issues". Something is very rotten in the VM.
