Notes:

Windows 2008 is only supported from vSphere 4.0 due to the persistent SCSI-3 reservation support requirement.

For a list of supported guest operating systems for vSphere 4.x/5.x, see Microsoft Clustering on VMware vSphere: Guidelines for Supported Configurations (1037959).

The information in these documents is only as current as the document's last modified date. Check frequently for additions and updates to the release notes.

For information regarding supported 64 and 32-bit Windows guests, see the documentations listed in the preceding table.

Sharing RDMs between two virtual machines without a clustering solution is not supported. For more information, see Microsoft Clustering on VMware vSphere: Guidelines for Supported Configurations (1037959).

When a cluster solution is qualified, it receives a Design for Microsoft Windows Server 2003/2008 logo and is listed in the Windows Server Catalog under Cluster Solutions.
