Dynamic Memory Beta – Supported Guest Operating systems

At TechEd this year we announced that dynamic memory would be supported for virtual machines that were running the following guest operating systems:

• Windows Server 2003 Web, Standard, Enterprise & Datacenter (32-bit and 64-bit)
• Windows Server 2003 R2 Web, Standard, Enterprise & Datacenter (32-bit and 64-bit)
• Windows Server 2008 Web, Standard, Enterprise & Datacenter (32-bit and 64-bit)
• Windows Server 2008 R2 Web, Standard, Enterprise & Datacenter (64-bit)
• Windows Vista Enterprise & Ultimate (32-bit and 64-bit)
• Windows 7 Enterprise & Ultimate (32-bit and 64-bit)

But not all of these operating systems will support dynamic memory with the beta release.  Only the following operating systems are supported with the beta release:

• Windows Server 2003 Enterprise & Datacenter (32-bit and 64-bit)
• Windows Server 2003 R2 Enterprise & Datacenter (32-bit and 64-bit)
• Windows Server 2008 Enterprise & Datacenter (32-bit and 64-bit)
• Windows Server 2008 R2 Enterprise & Datacenter (64-bit)
• Windows Vista Enterprise & Ultimate (32-bit and 64-bit)
• Windows 7 Enterprise & Ultimate (32-bit and 64-bit)

The following guest operating systems will be supported after the beta release:

• Windows Server 2003 Web & Standard (32-bit and 64-bit)
• Windows Server 2003 R2 Web & Standard (32-bit and 64-bit)
• Windows Server 2008 Web & Standard (32-bit and 64-bit)
• Windows Server 2008 R2 Web & Standard (64-bit)
