Creating a special template is usually preferred over (https://pve.proxmox.com/wiki/Duplicate_Virtual_Machines) (Duplicate Virtual Machines) cloning an existing VM .  Deploying virtual machines from templates is blazing fast, very comfortable and if you use linked clones you can optimize your storage by using base images and thin-provisioning.  Proxmox VE includes container based templates since 2008 and beginning with the V3.x series, additionally KVM templates can be created and deployed.  Definitions  VM  - KVM based virtual machine Templates  - Templates are pre-configured operating system environments that deploy in a couple of clicks Linked Clone - A linked clone VM requires less disk space but cannot run without access to the base VM Template Full Clone - A full clone VM is a complete copy and is fully independant to the original VM or VM Template, but requires the same disk space as the original.  Create VM Template  Templates are created by converting a VM to a template.  Install your VM with all drivers and needed software packages Remove all user data, passwords and keys - In order to do this run sysprep on Windows or similar tools or scripts on Linux and just power-off the VM. Right-click the VM and select "Convert to template"  Note  As soon as the VM is converted, it cannot be started anymore and the icon changes. If you want to modify an existing template, you need to deploy a full clone from this template and do the steps above again.  OS specific notes for Templates  For productive usage it is highly recommended that a template does not include any data, user accounts or SSH  keys so you should remove all before you convert the VM to a template. On Linux systems you should remove SSH host keys, persistent network MAC configuration and user accounts and user data. Windows offers a bunch of tools for this, e.g. sysprep.  For testing purposes it may be useful to use a fully installed OS as a template.   GNU/Linux  Ubuntu: e.g. install with 'OEM mode' (press F4) CentOS7: Most steps in this (https://github.com/rharmonson/richtech/wiki/CentOS-7-1511-Minimal-oVirt-Template) guide are valid for PVE too.  Windows 7  (http://technet.microsoft.com/en-us/library/ee523217(v=ws.10).aspx) Building a Standard Image of Windows 7: Step-by-Step Guide   Deploy a VM from a Template  Right-click the template, and select "Clone".  Full Clone  A full clone VM is a complete copy and is fully independent from the original VM or VM Template, but it requires the same disk space as the original.  Linked Clone  A linked clone VM requires less disk space but cannot run without access to the base VM Template.  Linked Clones works for theses storages: files in raw, qcow2, vmdk format (either on local storage or nfs); LVM-thin, ZFS, rbd, sheepdog, nexenta.  It's not supported with LVM & ISCSI storage.
