Can I store virtual machines and virtual hard disks on a network share?
Yes. If you’re supporting many different virtual machines, you might have a problem managing all of the virtual hard disk files you need for all of your installations of your virtualization platform product. One way to help consolidate this is to store all of your virtual machines on a networked device, such as a standard Windows file share or on a Network-Attached Storage (NAS) device. If your virtual hard disks (VHDs) are configured to be read-only (e.g., if you’re using differencing disks or undo disks), you can even have multiple virtual machines accessing the same VHD files at the same time. Configuring this is pretty simple. For example, on Microsoft Virtual Server, just add the UNC path you need to the search path in the configuration of Virtual Server. Standard security requirements apply. The service account under which the Virtual Server service runs must have the necessary permissions.
