Customization of Disposable VM
==============================
It is possible to change application settings for each new DispVM. This can be done by customizin DispVM template:
It is possible to change the settings of each new Disposable VM (DispVM). This can be done by customizing the DispVM template:
1. Start terminal in 'fedora-18-x64-dvm' VM (via command line, it is not listed in Qubes Manager nor system menu):
1. Start a terminal in the `fedora-18-x64-dvm` TemplateVM by running the following command in a dom0 terminal. (By default, this TemplateVM is not shown in Qubes VM Manager. However, it can be shown by selecting "Show/Hide internal VMs.")
``` {.wiki}
qvm-run -a fedora-18-x64-dvm gnome-terminal
```
2. Change application settings (eg you can start firefox and change default search engine, install some plugins etc).
3. Create empty /home/user/.qubes-dispvm-customized file:
2. Change the VM's settings and/or applications, as desired. Note that currently Qubes supports exactly on DispVM template, so any changes you make here will affect all DispVMs. Some examples of changes you may want to make include:
- Changing Firefox's default startup settings and homepage.
- Changing Nautilus' default file preview settings.
- 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 TorVM, for example. It is also useful if you sometimes wish to open untrusted files in a network-disconnected DispVM.
3. Create an empty `/home/user/.qubes-dispvm-customized` file:
``` {.wiki}
touch /home/user/.qubes-dispvm-customized
```
4. Shutdown the VM (either by poweroff from VM terminal, or qvm-shutdown from dom0 terminal).
5. Regenerate DispVM template:
4. Shutdown the VM (either by `poweroff` from VM terminal, or `qvm-shutdown` from dom0 terminal).
5. Regenerate the DispVM template:
``` {.wiki}
qvm-create-default-dvm --default-template --default-script
```
**Note:** All above require at least qubes-core-vm \>= 2.1.2 installed in template.
