Using Disposable VMs
|
||
====================
|
||
|
||
Background
|
||
----------
|
||
|
||
See [this article](http://theinvisiblethings.blogspot.com/2010/06/disposable-vms.html) for a background on why would one want to use a Disposable VM and what it is.
|
||
|
||
Opening a file in a Disposable VM (via GUI)
|
||
-------------------------------------------
|
||
|
||
In some AppVM, right click on the file you wish to open in a Disposable VM (in the Nautilus file manager), then choose Scripts -\> Open in Disposable VM. Wait a few seconds and an default application for this file type should appear displaying the file content. This app is running in a whole new VM -- a disposable VM created for the purpose of view this very file. Once you close the viewing application then whole Disposable VM will get destroyed.

||
|
||
Opening a fresh web browser instance in a new Disposable VM
|
||
-----------------------------------------------------------
|
||
|
||
Sometimes it is convenient to open a fresh instance of Firefox within a new fresh Disposable VM. This can be easily done by using the Start Menu: just go to Start -\> Disposable VM -\> Firefox and wait a few seconds until a web browser starts. Once you close the viewing application then whole Disposable VM will get destroyed.

|
||
|
||
Opening a file in a Disposable VM via command line (from AppVM)
|
||
---------------------------------------------------------------
|
||
|
||
Use the `qvm-open-in-dvm` command line (from your AppVM), e.g.:
|
||
|
||
``` {.wiki}
|
||
[user@work-pub ~]$ qvm-open-in-dvm Downloads/apple-sandbox.pdf
|
||
```
|
||
|
||
The qvm-open-in-dvm will not exit until you close the application in the Disposable VM.
|
||
|
||
Starting an arbitrary application in a disposable VM via command line (from Dom0)
|
||
---------------------------------------------------------------------------------
|
||
|
||
**Note:** Normally there should be no need for doing this -- this is just for Qubes hackers ;)
|
||
|
||
``` {.wiki}
|
||
[joanna@dom0 applications]$ echo gnome-terminal | /usr/lib/qubes/qfile-daemon-dvm qubes.VMShell dom0 DEFAULT red
|
||
```
|
||
|
||
In fact the Disposable VM appmenu used for starting Firefox contains a very similar command to the above. Please note, however, that it generally makes little sense to start any other application other than a Web Browser this way...
