Microsoft has released Virtual Machine Additions for Linux

Virtual Machine Additions for Linux are designed to improve the usability and interoperability of running qualified Linux operating systems as guests or virtual machines of Virtual Server 2005 R2 SP1.

Now with support for SuSE Linux Enterprise Server 10

Microsoft is committed to testing and supporting many third-party operating systems for use as guest operating systems on Virtual Server 2005 R2 SP1 virtual machines. To help make sure that you have a favorable experience when you run third-party guest operating systems in Virtual Server 2005, Microsoft Product Support Services (PSS) has created a product support model for these third-party guest operating systems. This support model is consistent with the support model that is used for Virtual Server 2005 R2 SP1. Product support for the Virtual Machine Additions will be provided through the normal support channels available for Virtual Server 2005 R2 SP1.
