Hi all,
I still try to get jessie with systemd working in an unprivileged
container, without any luck.
The host system is Debian wheezy with an updated shadow package,
a kernel 3.18.4 with lxcfs-0.5, cgmanager-0.35 and LXC-1.1. But
all I get is (it is wheezy updated to jessie):
$ lxc-start -n wheezy -F
WARN: could not reopen tty: Permission denied
Mounting cgroup to /sys/fs/cgroup/cpu,cpuacct of type cgroup with
options cpu,cpuacct.
Failed to mount cgroup at /sys/fs/cgroup/cpu,cpuacct: Operation not
permitted
Mounting cgroup to /sys/fs/cgroup/net_cls,net_prio of type cgroup
with options net_cls,net_prio.

Detected virtualization 'lxc'.
Detected architecture 'x86-64'.
Welcome to Debian GNU/Linux 8 (jessie)!
Set hostname to <wheezy>.
Failed to configure loopback device: Operation not supported
Using cgroup controller name=systemd. File system hierarchy is at
/sys/fs/cgroup/systemd/wheezy/wheezy-1.
Failed to install release agent, ignoring: No such file or directory
It hangs after "Set hostname to ..." for a few seconds (100% CPU
systemd in container), then there are the two Failed messages and
finally I need a kill -9 to terminate the container.
lxcfs in debug mode shows this:
unique: 46, opcode: GETXATTR (22), nodeid: 23, insize: 68, pid: 9556
unique: 46, error: -38 (Function not implemented), outsize: 16
I'm not sure, if this is really a problem.
The debug-log is attached.
Does anyone have an idea, what is going on? Where's my mistake?
Best regards
Dirk
