Tested with the experimental packaging (after getting over the shock at seeing the package explosion), and the VM comes up, so yes, it’s fixed, in experimental. Thanks for the heads-up, I upgraded to that version in the meanwhile. bye, //mirabilos -- tarent solutions GmbH Rochusstraße 2-4, D-53123 Bonn • http://www.tarent.de/ Tel: +49 228 54881-393 • Fax: +49 228 54881-235 HRB 5168 (AG Bonn) • USt-ID (VAT): DE122264941 Geschäftsführer: Dr. Stefan Barth, Kai Ebenrett, Boris Esser, Alexander Steeg

Bug#939983: error: Unable to read from '/sys/fs/cgroup/unified/machine/cgroup.controllers'
Hi, I’ve had to downgrade in the meantime, since #935734 at least has a workaround. FWIW, the GNU Guix people have the same problem, and with a different path, others: https://www.redhat.com/archives/libvir-list/2019-July/msg01310.html https://bugzilla.redhat.com/show_bug.cgi?id=1751120 I have this: tglase@tglase:~ $ mount | fgrep cgroup tmpfs on /sys/fs/cgroup type tmpfs (rw,nosuid,nodev,noexec,mode=755) cgroup2 on /sys/fs/cgroup/unified type cgroup2 (rw,nosuid,nodev,noexec,relatime,nsdelegate) cgroup on /sys/fs/cgroup/elogind type cgroup (rw,nosuid,nodev,noexec,relatime,xattr,release_agent=/lib/elogind/elogind-cgroups-agent,name=elogind) So, s!/machine!! on the path would most likely make it work. bye, //mirabilos -- tarent solutions GmbH Rochusstraße 2-4, D-53123 Bonn • http://www.tarent.de/ Tel: +49 228 54881-393 • Fax: +49 228 54881-235 HRB 5168 (AG Bonn) • USt-ID (VAT): DE122264941 Geschäftsführer: Dr. Stefan Barth, Kai Ebenrett, Boris Esser, Alexander Steeg ** Mit der tarent Academy bieten wir auch Trainings und Schulungen in den Bereichen Softwareentwicklung, Agiles Arbeiten und Zukunftstechnologien an.
