I've update parallels desktop 8 last version and installed new windows 7 VM. After I've downloaded and installed windows 8 pro. All works but there are a problem with video resolution. max resolution on my iMac 27 is 1920x1200 (in windows 7 2560x1440) and aspect ratio is 4:3 not 16:9 I think problem is caused to video driver. In windows 8 there is Base Microsoft Video driver but in windows 7 there is Parallels Display Adapter. Strange thing because previous I've installed windows 8 preview versione and video resolution was great. Any solution? PS: same problem on my macbook air..
