When update?? This fix is horrible...
I am having a similar problem although I am not sure it's the same. I get a BSOD on prl_vadd and some memory reference error. Perhaps your prl_vm_app and prl_vadd are related? My issue is also a known issue and is related to the video driver. Apparently Windows doesn't like the driver and it renders the screen rrrreeeeeaaalllyyyy s l o w l y. It gets the CPU maxed out and grinds the whole machine to the speed of an 8088. Parallels needs to fix this.
I tried this fix, called "prl_fix" and it worked once. http://kb.parallels.com/en/5774 Then my computer lost power at 20% of my battery (which was weird) and when I restarted the problem was back again. This time the "fix" did not fix and now I BSOD on a regular basis.
Not sure if this will help you but it might be worth trying. I am running a MacBookPro Core2Duo 2.33.
PD4 is positively the worst upgrade to a software since Windows ME. They should not have made it a one way ticket from PD3 to PD4. If they had not we'd all be working right now and running PD3 until they figure all this out. Certainly someone must have tested this software before the rollout?!! Only thing I can figure is they were greedy for the money upgrade and released it about 6 months early.
The good thing is that PD4 has pushed me to move everything to the MAC side so my goal is by 12/1 to be completely out of windows except for one or two programs. PD4 and Bill Gates can pound sand.
No problem with my installation of PD4 with Windows XP or with prl_vm_app.
My CPU usage hovers around 2% which can hardly be called high, let alone excessive.

Parallels is essential. Absolutely a great resource.
try that guys : http://forum.parallels.com/showthread.php?t=31944&page=3
fixed all my issues (I am the one who started this thread and complained a lot!)
Please check your processor driver under Windows:
Start->Control Panel->Administrative Tools->Computer Management->Device Manager->Processors
If you see the yellow triangle with an exclamation mark, right-click the item and say "Update Driver"
I used to design a calculating complex based on Intel 8088 while I was at my third year in the University
Cannot find any "processor" item in my hardware window... the only yellow mark is beside "parallels paravirtualization driver" - tried to update the driver, but nothing, nada. Winupdate couldn't get any update. What can I do from there ?
What's under non Plug'n'Play devices in the list? Check if it is there by this KB article -- http://kb.parallels.com/en/5810
Guess I maybe found the cure - could be an Autocad 2008 bug - found this on the web:
1. Open the drawing
2. Enter -SCALELISTEDIT in the command line
3. Type R for the following command line prompt; Enter option [?/Add/Delete/Reset/Exit] :
4. Type Y for the final command line prompt; Reset scale list to defaults? [Yes/No] :
5. Save and close to preserve the changes.
Seems to work till now - just have to repeat the command in each drawing I open.
Don't know if this can explain the issue with the CPU overload thing, but maybe it can help autocad 2008 users in the same case...
prl_perf_ctl output for prl_vm_app cpu load issue
Upgraded an XPSP3 VM from PD3 to PD4. Hasn't run too fast since the update a few weeks ago, but now it's horribly slow, with prl_vm_app chewing up CPU. Here is my output.
Maverick:~ jkennemer$ sudo prl_perf_ctl -a -n -l 2

Paravirtualization Driver Version
I tried to reinstall Parallels tools as previous posts have mentioned. Since then, the Parallels Paravirtualization Driver shows an exclamation in Device Manager stating it did not load properly. I rolled back to the 11/8/2008 (4.0.3525.9304) version and the system began to respond much better.
Sounds like a fix is needed ASAP.
What I think that Parallels Tools installation is somehow messed
Try to uninstall Parallels Tools
and in c:\windows\system32\drivers delete all prl and prl_ files
(or move to c:\backup)
Reinstall Parallels Tools
Thanks for the clarification. I did this and the system is telling me it needs to install hall.dll. I have mislaid my windows disk - any way to clear this up without finding the disk? I'm getting messages about missing dlls every time I boot up that I cancel out of (two with each boot). FYI - I did the switch to two processors than back to one processor then back to two processors and at least at the moment that seemed to help with the CPU usage a lot. I'm now down at 10% CPU for prl_vm_app - the lowest I've seen it get to since the upgrade to 4.0.
You need to select correct boot option, I suppose you have Boot Camp, and thus you need to select Windows Xp, immediately after boot
For what it is worth, I am getting the High CPU usage problem when running MacOS X Server as a guest. This is NOT simply a windows issue. Parallels is so unstable with MacOS X Server guest, I have to do a complete reinsatll twice now, and finally revert to using a single CPU with MacOS X server guest.
Your case is very interesting,
Could you please set 2 CPU and submit problem report,
I 've never seen that in Mac OS guest 2 CPU usage may cause 100% usage
Sorry, I am on holiday now until January, so this will have to wait until after Xmas. This was on a Mac Pro with 4 CPUs.
When I set to 2 processors, the VM immediately gave a kernel panic and stopped again.
Problem report 26324 sent in.
Please try the version 3804 (beta) to see if it can be fixed.

An end user's comment
I noticed that my MacOS programs slowed to a crawl (running safari, itunes, iphoto, photobooth, and finder with parallels 4.0) and some crashed (photobooth) when running Parallels 4.0 -next time I run it, will have to check and see what is causing it.
