I am a QubesOS heavy user. I separate almost everything. Because of it I have a ton of VMs I have to switch to Fedora 34. Is there a way to run it in one single command from dom0?
Note: I have ~20 VMs called storage-XX.
My idea was: qvm-prefs storage* template fedora-34
Unfortunately, this does not work. Also, I would have to match a number of groups. Much more advanced would be a command that simply matches each VM on fedora-33 and switches to fedora-34.
I am familiar with the in-place upgrade method. However, I’m looking more for a quick and dirty method without much risk of screwing something up:
You also can do this in the GUI, means open Qubes Manager > System > Manage Templates for Qubes. Then select all qubes, which have to be changed and down on the list change the drop down list to the desired template… click ok
