Hardware virtualization software lets you run multiple operating system instances at the same time on a single computer. Microsoft has two software offerings, Microsoft Virtual PC and Microsoft Virtual Server, that provide this functionality. Third parties also have software in the market that provides this functionality. This article describes support provided by Microsoft for its software running together with non-Microsoft hardware virtualization software.

Except as described in this article, Microsoft does not test or support Microsoft software running together with non-Microsoft hardware virtualization software. For Microsoft customers who do not have a Premier-level support agreement, Microsoft will require that the issue to be reproduced independently from the non-Microsoft hardware virtualization software. Where the issue is confirmed to be unrelated to the non-Microsoft hardware virtualization software, Microsoft will support its software in a manner that is consistent with support provided when that software is not running together with non-Microsoft hardware virtualization software.

For Microsoft Premier-level support customers running non-Microsoft hardware virtualization software from vendors with which Microsoft does not have an established support relationship that covers virtualization solutions, Microsoft will use commercially reasonable efforts to investigate potential issues with Microsoft software running together with non-Microsoft hardware virtualization software. As part of that investigation, Microsoft may require the issue to be reproduced independently from the non-Microsoft hardware virtualization software. Where issues are confirmed to be unrelated to the non-Microsoft hardware virtualization software, Microsoft will support its software in a manner that is consistent with support provided when that software is not running together with non-Microsoft hardware virtualization software.

Microsoft will jointly support certain non-Microsoft hardware virtualization software from vendors with which Microsoft has established a support relationship that covers virtualization solutions. This joint support will include coordinating with the vendor to investigate support issues. As part of the investigation, Microsoft may require the issue to be reproduced independently from the non-Microsoft hardware virtualization software. Where issues are confirmed to be unrelated to the non-Microsoft hardware virtualization software, Microsoft will support its software in a manner that is consistent with support provided when that software is not running together with non-Microsoft hardware virtualization software.
