Enter the name of the new VM in the Name box. You can choose any name you like, but a descriptive name is usually best. Although it is advisable to avoid having multiple VMs with the same name, it is not a requirement, and XenCenter does not enforce any uniqueness constraints on VM names.
It will make it easier for you to manage different VMs if you give them meaningful, memorable names, for example, a name that describes the VM's operating system (Windows 7 64-bit JA), application software (Citrix XenServer Web Self Service v1.0 (Build 9057)), or role (db-server, Outlook Server, Windows 7 Test) can help you to identify it later on.
It is not necessary to use quotation marks for names that include spaces.
You can also include a longer description of the VM on this page of the wizard (optional).
