Problem: (1) Windows 8 Metro UI start menu and apps not rendering when run as virtual machine under Parallels 8 on new Haswell-based MacBook Air.
Solution: With virtual machine loaded but inactive (as usual for config changes) Go into Parallels/Virtual Machine/Configure/Hardware/Video. Set hardware acceleration to DirectX9.
Notes: At your own risk, but it worked for me. May also fix problems running Internet Explorer in similar environment, but I have not confirmed this.
