Hi, I have uninstall PD6 and installed PD7 on my Late 2009 27" iMac today. I created a new VM for my Lion from the recovery partition. Fresh install from internet thru apple server and installed a 10.7.1 VM. However, I got a few stability problem. 1/ The dock keep on restarting if I click on a folder (like Application Folder that I create a shortcut there) every few times. 2/ App Store crashed and Update crashed when I click on the "downloading" dialog box or somewhere inside the app. 3/ The whole VM is comparatively more sluggish (in screen refresh and folder display) than Windows 7 guest. These were with and without the Parallels Tools installed. The VM config is simply default settings except I assigned 1 core, 64GB HD and 4GB RAM for the session. The Host is running Lion 10.7.1 with 16GB RAM 2.8G i7 (no antivirus, no firewall enabled, just a few Lion compatible apps installed). Anything I can do ? I upgraded to PD7 simply for OSX in VM. Please help.
