For the heck of it last night I loaded up Lion as a virtual machine on my iMac running 10.6.7. It loaded fine and even updated to 10.7.1 with no problems. The only "issue" I'm having is it's using a display resolution of 1024 x 768 and I can't find any display settings within Fusion or Lion to be able to make it larger (my monitor resolution is 1920 x 1200 - so I'd like a bigger "guest" window). If I grab a corner of the window and drag it, it gets larger, but just starts pixelating the contents since the Lion guest is still only running at 1024 x 768. Any suggestions?
