How do I run Windows 8 via virtualization?

I would like to run Windows 8 within a virtual machine under Ubuntu.
My quick attempt with VMware failed.
Has anyone reached to run Windows 8 on Ubuntu?

ps: Microsoft just released a public preview of Windows 8 -- see http://dev.windows.com


Solution 1:

Will work with Virtualbox. You have to enable hardware virtualization in the settings, VT-x and Nested Paging.

Solution 2:

Virtualbox didn't work for me, but VMWare did.

make sure to enable hardware virtualization in your BIOS
