1. Start a terminal in the `fedora-26-dvm` qube (or another base for DispVM) by running the following command in a dom0 terminal. (If a qube have `appmenus-dispvm` feature set, there is no menu entry to start applications directly in it, instead of Disposable VM based on it). 1.

(If you enable `appmenus-dispvm` feature (as explained at the top), applications menu for this VM (`fedora-26-dvm`) will be "Disposable: fedora-26-dvm" (instead of "Domain: fedora-26-dvm") and entries there will start new DispVM based on that VM (`fedora-26-dvm`). Not in that VM (`fedora-26-dvm`) itself).

- Changing Nautilus' default file preview settings. - 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 DipsVMs 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. - Changing the DispVM's default NetVM. For example, you may wish to set the NetVM to "none."
