Couple of days back I tried to open my existing Dynamics AX VM to find that it expired on Nov 15.
Lachlan has put up a blog post about the new VM's which Microsoft has released here in this link http://blogs.msdn.com/b/lcash/archive/2010/11/03/announcement-of-microsoft-dynamics-ax-2009-demonstration-vm-november-2010-refresh.aspx
VM OS now comes in 3 flavors
a. Hyper-V with Windows Server 2008
b. VPC 2007 with Windows Server 2008
c. VPC 2007 with Windows Server 2003
