v3 to v4 experience

Spent a few hours, finally upgraded to v4. Some features are nice but the parallels runs slower than before (v3) and it's much more memory hungry. I allocated 1gb for it and it literally occupied that much even when I didn't run much. Worse, it wouldn't release the memory after I pause it, contrary to what the help page said. I think this explains why both windows and hosting OSx become slower after the upgrade (I only have 3gb memory total).

 

Run Activity Monitor and check how much CPU time prl_vm_app process comsumes. If it's an incredible value try this KB article: http://kb.parallels.com/en/5810, also check this one

 

I have the same problem. I tried the two fixes you mentionned but none of them worked properly. Second one seems to work for one of my VMs but not for the other.

I'm also a V3->V4 user.

 

Could you please check this article

Hi John,

This article has been pointed out by your colleague Estrelnikov earlier in the thread (the link behing 'this' in his message) . Then I already tried this fix. It improved the situation for one of my VMs (I use two), but not for the second for a reason I ignore. The second still yomps 100 percent of the processor I assigned although I do nothing with the VM.

My config is MacPro from January 08 2x4 proc 8 Go RAM. XP Home on one computer (fixed) and XP Pro on the other.

 

The second VM, which I thought was fixed, is now back to 100 percent of its CPU. I cannot explain that.

 

1. Open c:\WINDOWS\System32\drivers and delete all files prl*.* but not
prl_*.*, and delete prl_pv32.sys
Then reboot.

2. If step 1 will not help, then you can just uninstall Parallels Tools
(Start->Settings->Control Panel->Add or remove programs -> Parallels
Tools -> Remove)
Without Parallels Tools installed guest Windows normally should start in
2-3 minutes maximum. Then you can install Parallels Tools again (in
MacOS top menu: Virtual Machine -> Install Parallels Tools)

 

Thanks. I'll try this asap and let you know.

 

I did all as you required. Installed Tools as well but noticed no improvement. I still have one computer taking all ressources with prl_vm_app.

 

And I also lost Internet connectivity on one of the VMs. Cool.

 

Please create ticket in support we investigate situation

 

There is no really ticket to create. I think we all need a fix for the V3-V4 bugs.

We need to investigate situation to get some conclusion
Please decide on this

 

I have deleted the messed up VM and converted the back-up of the messed-up VM and so far it's OK.

What is the link for the ticket?
