Using Parallels Desktop 7 on Mac. I would like to see warnings about hardware configuration settings of the vm that would not be compatible based on the OS type set in the General settings. For example, I set the video memory of a Windows XP vm to 512 megs and had to search the knowledge base to find out why it was not being recognized by the vm. I clearly found my answer stating that Windows XP simply did not support more than 256 megs of video memory. It would have been nice to be warned by the program and avoid the waste of time.
