How to file a helpful issue

Qubes OS release

R4.2 (likely R4.1 too)

Brief summary

Setting default-kernel to invalid value prevents starting any qube. qubesd should refuse to set invalid value.

Steps to reproduce

qubes-prefs default-kernel xxx

Expected behavior

xxx value is refused

Actual behavior

Value is accepted and no qube can start due to non-existing kernel.

It appears that the readily available property-pre-set:kernel event and on_property_pre_set_kernel of QubesVM could not be reused here.

Doing it at qubes-core-admin-client level will not be a proper fix?

No, it should be done on the backend side.

It appears that the readily available property-pre-set:kernel event and on_property_pre_set_kernel of QubesVM could not be reused here.

I think it can be extracted to a helper function, and then connected to a property-pre-set:default_kernel event on the app object.

Ok. It is done at Daemon level.
