When I start XTerm in `my-new-dvm` the new XTerm window starts in a 
disp disposable VM, as it should.


When I start Firefox in `my-new-dvm`, however, Firefox starts up in 
the underlying `my-new-dvm` template, not in a disp disposable VM. 
This means that the Firefox browsing history and prefs are saved, any 
malware gets to persist, etc.


Comparing the output of `qvm-prefs my-new-dvm` and `qvm-prefs my-dvm`, 
all settings are identical except for things that should obviously be 
different (the netvm, the GUID, the IP address, etc).


After further testing, the problem does not appear when cloning a Whonix 
workstation dispVM -- the problem only appears when cloning a 
Fedora-based dispVM.

Any idea what the problem could be?
