Unhappy with 4.0 upgrade proccess

I've been running parallels for a few years now, I have a home network where I keep my network admin skills up to date, and parallels has always allowed me to do this without issue. I have a dual cpu, dual core mac pro with 9 gig of ram, 4x 500g sata drives.

I run 3 VM's.
-Server 2003 Std with Exchange 2003
-Server 2008 Std as a DC
-Server 2008 Std as a Terminal Serv.

Saturday I purchased the upgrade to parallels 4.0, and now I wish I had not.

It took most of the day saturday to get my network back to the way it once was.

The server 2008's machines were blue screening upon loading because of a parallels driver that after a few hours of fighting with the OS, booting safe mode, and finally goggling the specific driver, I had to manually delete the offending file, and reinstall parallels tools. All the while, parallels was trying to auto-log into my machine with a local account, on a domain controller.

I had two physical 500g hdds attached as physical drives in the 2003 exchange box, and I when I try to attache these drives as physical drives, I'm given an address conflict. I've verified that the address is free, yet when I try to boot the machine it tries to do an upgrade, which after 2 hours.. FAILS..

I've had to create significantly slower virtual disks and copy nearly a terabyte of music, movies and personal documents to them, taking well over 12 hours to complete.

I still have not been able to get my backup software working again, as it requires the physical disk to where it has initialized itself.

so, all in all, I spent an entire weekend fighting with this upgrade, and now I've found that the entire setup is much, much slower. There's several parallels applications that mysteriously start up and eat up 100% of the CPU for hours. network performance AND disk IO is significantly decreased.

At this point, I'm one very unhappy upgrader, and to top all of this off, I cant imagine someone who is a novice at networking trying to acomplish this task. I've worked as a network administrator on windows networks for 15 years, and am now in charge of a senior windows networking staff.

Another feature that is still sorely missing from parallels is the ability to detach from the console of a VM, and get rid of it and allow the machine to run in the background.

Come on guys, get it right before you release the upgrades.
