There's been a bunch of reports of VM startup failures on Fedora 31 and elsewhere: https://bugzilla.redhat.com/show_bug.cgi?id=1751120 The reproducer I found is running a mock build, which adds a name=systemd cgroup to /proc/self/cgroup, which messes up libvirt's logic. The first patch has a bit more detail. I'm not positive this is entirely correct... maybe we should be doing something with that cgroup in some way? I'm kinda ignorant here. I also filed a systemd bug incase that behavior is unintentional. We probably want to change libvirt regardless though https://bugzilla.redhat.com/show_bug.cgi?id=1756143 Cole Robinson (2): vircgroupv2: Fix VM startup when legacy cgroups are defined vircgroup: Add some VIR_DEBUG statements src/util/vircgroup.c | 3 ++- src/util/vircgroupv2.c | 15 ++++++++++++++- 2 files changed, 16 insertions(+), 2 deletions(-) -- 2.23.0 -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
