I'm trying to fix issue #3303 (inability to use --verify-only with
qvm-backup-restore) but to do that I need to supply vm objects that are not
actual vms. Otherwise, the tool can't cope with archives containing vm names
not present in the live system.
I'm not sure what is the right approach for instantiating 'dummy' vm classes
(or at least ones that will be useful to the restore tool).
Quick-fix me wants to do: dummyvm = qubesadmin.vm.QubesVM(None, "dummy1")
...but I want it to be correct.
This will raise NotImplementedError on the first try to call any
AdminAPI method - like getting property. Better create DummyQubes class,
being subclass of QubesBase (see qubesadmin/app.py), and put empty
qubesd_call method there. Then use that instead of None for QubesVM
constructor. Something like this:
class DummyQubes(qubesadmin.app.QubesBase):
def qubesd_call(self, *args, **kwargs):
pass
dummy_app = DummyQubes()
dummyvm = qubesadmin.vm.QubesVM(dummy_app, "dummy1")
It works, but this seems to work as well:
new_vm = self.backup_app.domains[vm_name]
This may be preferable to adding a dummy class definition.
