How many virtual machines can Microsoft Virtual Server support per physical server?
Microsoft's documentation for Virtual Server 2005 indicates that you can run a maximum of 64 virtual machines per physical server, along with the following notes:
The practical limit of how many virtual machines you can run simultaneously depends on system resources, the amount of memory assigned to each virtual machine, and the total memory available on the physical computer. Virtual Server supports up to 3.6 gigabytes (GB) of RAM per virtual machine. ( Microsoft TechNet)
