- 64-bit Windows 8 does require 2GB+ of memory. That is a requirement stated by Microsoft for 64-bit, so hardly comes as a surprise. The more yuou can give it, the better, of course, but you will hit the usual trouble if you allocate over half the host memory available.
- 2+ VCPUs are not mandatory, however, for intensive tasks, obviously 2 virtual CPU’s will perform better than 1.
- Win8 DP/CP works fine with SATA disks in general. It’s simply not true that IDE is required.
- The graphics subsystem in Windows 8 is markedly different from Windows 7, which is why the currently Oracle VirtualBox 4.1 Guest Additions are so wobbly in operation. It seems it’s pot-luck as to which version you install of the 4.1 Guest Additions to get things working safely on your combination of real and virtual hardware; 4.1.8, 4.1.10 and 4.1.12 user are all reporting mixed successes and failures. The 2D/3D acceleration settings only apply when Guest Additions are installed, so without them, acceleration in the Windows 8 guest doesn’t really matter.
The one thing you can’t expect is consistency. My Windows 8 VM updated itself earlier this week and now any use of the Windows Explorer triggers and instant re-boot! AJS
