In fact a little issue emerged. I am describing it here just in case it is useful to others.
I have managed to:
- rename my old debian 13 to
debian-13-xfce-new, which is now the template for several VMs - Download the original
debian-13-xfce - Redefine the template for several VMs to be
debian-13-xfce.
However there is an issue now.
If I try to delete debian-13-xfce-new, it gives me this error:
This qube cannot be deleted, it is used as template for
default-mgmt-dvm
After a little search, I have found here that default-mgmt-dvm is a hidden VM. The last post (Dec 2024) proposes a solution to avoid issues, but I assume it has not been implemented yet in Qubes 4.3 rc2.
So I need to redefine the template for default-mgmt-dvm.
This cannot be done with the Qube Manager program, because it hides the default-mgmt-dvm. But it is possible using the terminal as follows:
qvm-pref default-mgmt-dvm template debian-13-xfce
Now I could finally delete debian-13-xfce-new and all is good.
