MSCRM 4.0 has joined the ranks of Microsoft supported software to be run in a virtual environment. MSCRM 4.0 is now supported to be run on Virtual Server 2005 in a production environment. Here's Microsoft's official statement on it:
Support policy for Microsoft Dynamics CRM 4.0 on a computer that is running Virtual Server 2005
Microsoft Dynamics CRM 4.0 is officially supported to run on a computer that is running Microsoft Virtual Server 2005 in production systems. In addition, the Microsoft Dynamics CRM team is committed to the following:
Continuing support for virtualized environments in future releases of Microsoft Dynamics CRM.
Testing Microsoft Dynamics CRM running on upcoming Microsoft virtualization technologies and publishing updated support policies as these technologies become available.
I fully expect to be hearing about support being available for virtualization on Windows Server 2008 soon, I'm sure they're just finishing their testing. So, keep your eyes open for that.
