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.

Microsoft provides technical support for third-party guest operating systems by using the standard Premier and Professional channels. If you report an issue that occurs while you are running a supported third-party guest operating system in Virtual Server 2005, you are directed to a team of Microsoft support professionals. These support professionals are trained to troubleshoot issues that are related to interoperability between the following list of third-arty guest operating systems and Microsoft Virtual Server 2005 R2 SP1.
