Hello, After migrating my templates to Fedora 26, I have also created a new disposable VM, based on a Fedora 26 template.
I have set the new DVM to start, from all other AppVMs, as such the DVM should not be referenced to in any other app vm. I tried to remove the default DVM, but it didn't work. What do I need to do, to get rid of the old (Fedora 25 based) DVM which comes with the default Qubes 4rc3 isntallation ?  my procedure to create a new Fedora 26 DVM: ---8# Create a new Disposable App-VM "my-dvm" which is based on a custom template t-fedora-26 qvm-create --template t-fedora-26 --label red --property template_for_dispvms=True --class=AppVM my-dvm # TEST: Start an application in this dvm qvm-run --dispvm=my-dvm xterm # Fix menu entry from Domain: my-dvm to Disposable: my-dvm # https://groups.google.com/forum/#!msg/qubes-users/gfBfqTNzUIg/sbPp-pyiCAAJ # https://github.com/QubesOS/qubes-issues/issues/1339#issuecomment-338813581 qvm-features vmname appmenus-dispvm 1 qvm-sync-appmenus --regenerate-only my-dvm # Change the Disp-VM from an AppVM (here: my-untrusted) qvm-prefs --set my-untrusted default_dispvm my-dvm # Try to start something from this AppVM in a disposable VM qvm-run --auto my-untrusted 'qvm-open-in-dvm https:/google.de' # This should start a new dispvm which is based on your dvm-App ---8 Gesendet von ProtonMail mobile -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
