You sure about default_dispvm here?

Yes, see logs from qubesmanager tests:
'This qube cannot be removed. It is used as: <br> - <b>default_dispvm</b> for qube <b>anon-whonix</b>

if it's really used as default_dispvm for anon-whonix the removal should be blocked... the only thing that shouldn't be blocked is being a template (only) for preloaded disposables, that you are going to kill/remove below anyway.

Hum, then I need to do it another way because a disposable qube has the default_dispvm property set to its template, so it must be only if those two properties matches.

I don't like the code duplication.
Especially the part some lines below "see 'journalctl'" because not everything is returned to the caller. The preloads are introducing one extra discrepancy on top of device assignment only seen from dom0 journal.
I think there should be an API method to check if the qube is deletale and if not, the (vm, prop) is returned via exception. What do you think?

It's done this way because the caller may not see the whole system (it can be for example a GUIVM with access to a subset of qubes). Returning the whole list may leak info about other qubes that the caller should not see.
The utility function in core-admin-client is supposed to find where the qube is used - based on what the caller actually can see.

Make sense, thanks for the explanation.

All the client tools, qvm-remove and qube-manager show a nice view of dependencies, the journal/logs were not showing them. Discovered that qube names can end with a . dot... I guess and hope : will never be allowed in qube names.

I didn't find a better name than "GLOBAL" for the global property, it is using quotes to distinguish from a qube name. It prints as such:
ERROR: Cannot remove default-dvm as it is used by disp-test:template, sys-firewall:template, sys-usb:template, "GLOBAL":default_dispvm
