Disp VM's starting automatically after 4.3 upgrade

JaanK · May 13, 2026, 1:01pm

Qubes 4.3 (in-place upgrade from 4.2). Upgrade went smooth, but there is something strange. At system startup two disposable VM’s open up automatically and go to “paused” state. No input from me, default-dvm has “start cube automatically on boot” option turned off. If I kill them, and suspend the system, after wake-up they are back (with different numbers ofc). Any ideas where to look for solution ?

Depends: - https://github.com/QubesOS/qubes-attachment/pull/75 - https://git…hub.com/QubesOS/qubes-core-admin/pull/721 - https://github.com/QubesOS/qubes-issues/issues/10282 - https://github.com/QubesOS/qubes-attachment/pull/77 Graphs are finished, they should be added to `qubes-attachment` and also, I think it is a good idea to update the disposable documentation before this post is published, because the docs is outdated, I will do it this week and reference bits of the documentation in this post.

Its not a case of “[WTF]” … it’s a classic “RTFM”!

In retrospect - true

C: Qubes GUI tools ux P: default diagnosed pr submitted affects-4.3

### Qubes OS release Qubes OS 4.3 ### Brief summary My initial idea was that …such thing would not be necessary, I thought that by making it internal, people would just let it be. I guess the combination of curious people that do not read the release notes is very high. I think this will become worse once the there is no more preloaded disposable in release notes, and a new release comes some time from now. ### Steps to reproduce 1. See paused disposable qubes in the system tray, shown as internal, what does that mean? 2. See internal qubes after enabling it in qube manager, what are those paused disposable qubes? ### Expected behavior User understands that these qubes are manager by the system and what they are. ### Actual behavior User knows it is manager by the system, but is still curious to know what it is and how to control it. ### Additional information - https://forum.qubes-os.org/t/paused-and-hidden-disp-qubes/39034/7 It is kinda limited what I can do: - system tray tooltip can have markup (links), but leaving the widget hides the tooltip, meaning it is not clickable. - qube manager doesn't have tooltips on the rows Therefore, some tools can have a large explanation and pointers, while other tools can only have a brief text "Preloaded disposable", which will be let to the user to search on the docs for that string.

Note: I removed “[WTF]” from the title.
