For this reason, it is strongly recommended that you base the default DVM Template on a trusted TemplateVM.

R4.0 introduces the concept of multiple DVM Templates, whereas R3.2 was limited to only one.

This is a change in behaviour from R3.2, where DispVMs would inherit the settings of the AppVM from which they were launched.

Therefore, launching a DispVM from an AppVM will result in it using the network/firewall settings of the DVM Template on which it is based.

**Warning:** The opposite is also true. This means if you have changed anon-whonix's `default_dispvm` to use the system default, and the system default DispVM uses sys-net, launching a DispVM from inside anon-whonix will result in the DispVM using sys-net.

In particular, the *default* DVM Template is important becuase it is used by the "Open in DisposableVM" feature.
|
||||
This means that it will have access to everything that you open with this feature.
|
||||
For this reason, it is strongly recommended that you base the default DVM Template on a trusted TemplateVM and refrain from making any risky customizations to it.

Disposable VM (DispVM) in Qubes 4.0 can be based on any TemplateBasedVM. You can also choose to use different AppVMs for different Disposable VMs. To prepare AppVM to be a base for Disposable VM, you need to set `template_for_dispvms` property, for example:

- Changing Firefox's default startup settings and homepage.
|

- Changing default editor, image viewer.
|

- Changing the DispVM's default NetVM. For example, you may wish to set the NetVM to "none." Then, whenever you start a new DispVM, you can choose your desired ProxyVM manually (by changing the newly-started DispVMs settings). This is useful if you sometimes wish to use a DispVM with a Whonix Gateway, for example. It is also useful if you sometimes wish to open untrusted files in a network-disconnected DispVM.

The only exception is if you require something like VM to VM communication and have manually edited `iptables` or other items directly inside the firewall AppVM.

By default, a DVM Template named `fedora-XX-dvm` is created on most Qubes installations (where `XX` is the Fedora version of the default TemplateVM).
|

DVM Templates are not [TemplateVMs](#templatevm), since (being TemplateBasedVMs) they do not have root filesystems of their own to provide to other VMs.
|

Rather, DVM Templates are complementary to TemplateVMs insofar as DVM Templates provide their own user filesystems to the DispVMs based on them.

There are two main kinds of DVM Templates:

* **Dedicated** DVM Templates are intended neither for installing nor running software.

Rather, they are intended for *customizing* or *configuring* software that has already been installed on the TemplateVM on which the DVM Template is based (see [DispVM Customization]).

This software is then intended to be run (in its customized state) in DispVMs that are based on the DVM Template.

- Some keyboard layout set by KDE System Settings can cause [keyboard not working at all](https://groups.google.com/group/qubes-devel/browse_thread/thread/77d076b65dda7226). If you hit this issue, you can switch to console (by console login option) and manually edit `/etc/X11/xorg.conf.d/00-system-setup-keyboard.conf` (and `/etc/sysconfig/keyboard`) and place correct keyboard layout settings (details in linked thread). You can check if specific keyboard layout settings are proper using `setxkbmap` tool.

Prior to Qubes Beta1, for both cases, a block device (backed by a file in dom0 with a vfat filesystem on it) was attached to VM, file(s) copied there, and then the device was detached and attached to target VM. In the DispVM case, if a edited file has been modified, another block device is passed to requester VM in order to update the source file.
