Also - please remember to follow the Microsoft System Center Virtual Machine Manager website or follow my blog for more details on release dates. 90 days after the launch of Windows 2008, Hyper-V 2008 was released, so why not make it 90 dates for the release of SCVMM 2008 ? :-)
One of the more exiting things is the possibility to manage your ESX environments, as well as your Hyper-V and Virtual Server environments. This make this the basis solution for support and manageability for Virtual Servers.
With SCVMM2008 Administrators have the ability to give users a web portal for his/hers virtual machines. Give the users the ability to "lease" environments, based on a point system. - You can make a basis server, give it 10 points, make a medium server, give it 20 points. And then assign the user 50 points. That means the user can deply two medium, one basis. 5 Basis servers, or what ever other combination the user makes.
