Windows 8 Developer Preview : Pre Beta Version for Developers

I recently downloaded the Windows 8 Preview Developer edition from http://msdn.microsoft.com/en-us/windows/apps/br229516 and then tried running it as a virtual machine.Found the following issues :

- does not run on VMWARE 7

- runs on VMWARE 8

- Donno y...but runs at a pathetic speed on VMWARE 8 inspite of a good resourceful machine with upto 1.5 GB of RAM.

- Even on installation on VMWARE 8...doesnt show the NIC card so it has no access to Internet.So no updates.

- Runs at a horse's pace in VIRTUAL BOX.

- No NIC issues in virtual box.
