Hi again, I did another test by pinning the bookworm packages (7.6.0-1) and testing those. They exhibit the same behaviour as the patched libvirt, that is: in some cases, virsh destroy will show an error, but the container will be removed cleanly nonetheless.
This is an improvement over the previous situation, where it was impossible to destroy a domain. I'd thus suggest to move ahead with the patch, even if imperfect, as it then brings stable to the same state as testing in that regard (and I'll try to prepare a bug report for testing). kind regards, Jonas On Wed, 17 Nov 2021 16:10:57 +0100 Jonas Schäfer <jo...@wielicki.name> wrote: > Hi Guido, > > Thanks for your reply! > > On Wed, 17 Nov 2021 13:11:05 +0100 Guido Günther <g...@godiug.net> wrote: > > here's the missing link: > > > > https://salsa.debian.org/libvirt-team/libvirt/-/merge_requests/116 > > I took the artifacts from there and did another test run.
