Upgraded from build 3188 to Parallels 3.0 and ended up re-installing OS X - here is the list of problems - After upgrade, install asked to reboot - I did. 1) Reboot is slower than normal boots, after booting OSX feels slow, mouse is jerky. I fire up Parallels and have it migrate a Win XP VM to latest version - that one seemed to go well. 2) I start the migrated VM - Wait, wait, wait - nothing happens for a long time. Finally XP is up and running and new Hardware found wizard comes up but I cannot do anything on the XP desktop for long time. I notice the Menu has "Cancel Parallels tools installation" item which would mean that the parallels tools upgrade was running - but for long time (I mean really long) though I do not see the Parallels tools installation window and the new H/w wizard also doesn' go anywhere. I cancel the tools installation and attempt a XP reboot - keeping my patience I finally am able to restart XP 3) After restart again same story - new h/w and tool installation both stuck - this time I kill the new h/w wizard, cancel the tools install and then click install parallels tools. That seems to work - Tools installation is complete and I am asked to reboot XP. 4) After reboot I notice the VM takes significantly longer to boot than earlier 5) On each boot I get the Windows error reporting dialog - iTuneshelper crashes 6) I can no longer run VS2005 - just keeps crashing on startup It's hard to digest slower running OS X, slower running VMs, Crashing programs etc. I end up reinstalling OSX fresh and going back to build 3188 of Parallels. Fortunately I had kept a copy of the XP VM prior to migration - it continues to work fine. Bah.
Forgot to add 7) I created a new VM for Linux with 1024Mb RAM and I can't even start it - Parallels dies with error - something to do about not being able to allocate memory and suggesting to change a preference for virtual memory preallocation, changing it does not help. And I have 3Gb RAM and nothing else running - just trying to start this new VM for install. I decided not to bother with 3.0 until it is _more_ stable than the current version, which I suppose is going to be pretty unlikely at least in the short term.
I had a similar problem with VS2005 I experienced none of the the other problems you mentioned - everything installed and booted ok. I didn't have any performance problems either - but I wasn't looking for them either. However ---- When I opened a particular VS 2005 project file everything was fine until VS through up the actaul text editor with a file open from the last session. At that second VS 2005 gets a fatal exception in devenv.exe and VS dies. A lot of fooling around with updating the machine to the most current releases did nothing. So I went back to 3188 (I too kept a copy of the VS files). I did not have to re-install OS X.
I have two unresolved Parallels issues: 1. VS2005 ASP.NET debugging crashes the VM frequently. Like once a day. 2. Sometimes parallels tools starts causing "beach ball" pauses. Killing Tools rectifies it. Both of these problems are long-standing and I was hoping for some relief in the 3.0 upgrade.
