prl_vm_app yomping all my cpu time

Hi,

I've just upgraded to v4. On my MacBook Pro I have this problem...
http://forum.parallels.com/showthread.php?p=130435#post130435

But on my desktop it all works OK apart from prl_vm_app using all the CPU time it can. I currently have my Windows XP VM running on 1 CPU (I have dual core) and in activity monitor I can see it using 100% CPU, but if I enable both cores, it uses 200% CPU and the entire computer becomes almost unusable.

Any ideas?

Thanks...

Since no one has responded to this request, I will. This command was executed with the Windows XP Guest window opened, but the VM suspended. During this time 100% cpu was reported for the Parallels Desktop process:

After resuming the Guest VM here is the same command run again:

You don't need to download the new drivers... If you are familiar with Device Manager, just double-click on the processor device in Windows Device Manager, select the driver tab, and then choose update (you could even try roll-back as well). Let windows search for the driver itself. It worked for me. Nic.

This has been happening to me too. I do not see any problems in the Device manager, but all my upgraded VMs show at least 100% CPU useage. None of my new VMs do. I also had problems upgrading them and had to do this manually. I would certainly be nice if the Parallels folks actually responded to this.

All,

I hope you have all raised a support case on the support site (which was what I did... and even though they didn't solve the problem for me - I found a solution myself - they did eventually respond) so you will get a one-to-one support.

Can I suggest, that even if there is no exclamation point in the Windows Device Manager, that you at least try reinstalling the driver for the CPUs... maybe by letting Windows go to the update site (this time only) and install automatically. Or even rollback. Just because there is no exclamation point, doesn't mean it is not the same issue.

One last thing... I assume you have all checked Windows Task Manager and made sure nothing is running on the VM? This is the first thing I checked... I had virtually NO CPU utilisation within Windows, yet the parallels app was taking 100 (or 200) % of my Mac O

Not sure I can help any further!

I had the same problem, after I activated 2 CPUs yesterday. Repairing the CPU driver in XP also solved this issue for my installation.

Hi!

Kindly advise how to repair the CPU driver? I have tried to update the CPU driver but Windows asked me to put the CD to do it. Do I need to really put the Windows CD for this purpose?

For roll-back to the CPU driver, it said there is no roll-back one for me to do it.

Please help!
