[Pkg-libvirt-maintainers] Bug#809409: [libvirt-bin] Can't start LXC containers anymore: "error: At least one cgroup controller is required: No such device or address"

[Dirk Heinrichs]

Package: libvirt-bin
Version: 1.2.21-2
Severity: important

--- Please enter the report below this line. ---
I cannot start LXC containers anymore, which worked fine ~10 days ago. When I 
try to start a container today, I get this error:

% virsh --connect lxc:/// start stretch32
error: Failed to start domain stretch32
error: At least one cgroup controller is required: No such device or address

There hasn't been any change in the configuration of any container, nor an 
update of any libvirt or lxc related package since then. There has been a 
kernel update, though. Don't know whether that could be related or not.
