I have spent the last 2 days doing very in depth troubleshooting of this issue. I'm running some software CAD software on Windows 7 and XP through a Parallels VM. We have had no issues for years until we purchased the new i7 iMacs. Once we did, using the previously working VM's would cause Windows to crash when using this software. Basically opening two files with the software would cause the VM exit right to the start up screen, I can only assume Windows locked up.
I know for sure that the issue is with the new i7 computers because I was able to use the same hard drive in another computer (non i7) without any issue. I was also able to put the iMac (i7) into target disk mode and use that drive to boot a non i7 iMac and did not have an issue. The same exact VM's on the same exact drives function fine in non i7 machines. I have tried rebuilding the VM's, different i7 machines, using XP or Windows 7, using more/less RAM and CPU, changing some of the default parallels performance settings, etc.
I can get it Windows (7 and XP) to constantly exit (crash) and come back to the startup Windows VM screen doing certain functions with this software.
Is anyone seeing i7 related issues?
