Windows Server Virtualization (WSv) CTP only supports English version of the OS at the moment and has been tested only on selected hardware.

I have been trying to load Windows Server 2008 on SunFire x4200 (AMD Opetron x64-bit) hardware and wasn't even successful in installing the OS and then I found this link on MS Website which clearly says, what all hardware is tested and supported for the CTP release.

WSv Supports the following (for those who love bird's eye view)

• Hyper-V supports 32 and 64-bit SMP guests
• Supports iSCSI and Fibre Channel SAN
• Large memory allocation (more than 32 GB per machine)
• Integrated Virtual Switch

Recommended

• Only Windows OS
• Maximum 4 virtual processors be allocated to a VM running "Windows 2K8". Only 1 for "Windows 2K3"
• 1 virtual SCSI controller per VM
• 1 virtual network controller per VM
• 1 legacy virtual network controller per VM

Not tested and Recommended

• Not compatible with dynamic disks
• Disable hyperthreading
• PXE setting inside the VM BIOS doesn't support 64-bit OS deployment
• Do not create dynamically expanding virtual hard disks that are greater than 1 TB in size
• Clustering of VMs
• Clustering of physical server and quick migration
• Compacting of virtual hard disks
