### How Guest VMs Are Created From a Template After the RAS Template changes are committed to Parallels Remote Application Server, it will begin creating guest VMs from the template, one virtual machine at a time. The number of VMs that will be created is determined by the value specified in the Pre-created guest VMs field on the Properties page (see Configuring a RAS Template). As soon as a user connects to an existing guest VM, Parallels Remote Application Server begins creating a new VM from the template, so the number of pre-created VMs remains unchanged. Please note that creating a new VM from a template takes some time. If a VM is in the middle of being created, and no other VMs are available, the user will have to wait until the VM is ready. When a guest VM is no longer in use, and if the number of existing VMs exceeds the "pre-created" value, a VM is deleted after the time period specified in the Delete unused guest VM after field on the Properties page. If you didn't select that option, a VM is never deleted, but the total number of VMs will never exceed the value specified in the Maximum guest VMs field on the Properties page.
