Hi, This is my 1st unprivileged container.
Host is Ubuntu 14.04 64 bit. Container is Ubuntu 16.04 64 bit. It was created by lxc-create. LXC version is: 2.0.3. "nincs csatolva" means in English: not mounted. rattila@fcubi:~$ lxc-start -F -n lub8 umount: /usr/lib/x86_64-linux-gnu/lxc/sys/fs/cgroup/blkio/user/1000.user/c4.session/lxc/lub8 nincs csatolva umount: /usr/lib/x86_64-linux-gnu/lxc/sys/fs/cgroup/cpuset/user/1000.user/c4.session/lxc/lub8 nincs csatolva umount: /usr/lib/x86_64-linux-gnu/lxc/sys/fs/cgroup/cpu/user/1000.user/c4.session/lxc/lub8 nincs csatolva umount: /usr/lib/x86_64-linux-gnu/lxc/sys/fs/cgroup/cpuacct/user/1000.user/c4.session/lxc/lub8 nincs csatolva umount: /usr/lib/x86_64-linux-gnu/lxc/sys/fs/cgroup/devices/user/1000.user/c4.session/lxc/lub8 nincs csatolva umount: /usr/lib/x86_64-linux-gnu/lxc/sys/fs/cgroup/freezer/user/rattila/1/lxc/lub8 nincs csatolva umount: /usr/lib/x86_64-linux-gnu/lxc/sys/fs/cgroup/hugetlb/user/1000.user/c4.session/lxc/lub8 nincs csatolva umount: /usr/lib/x86_64-linux-gnu/lxc/sys/fs/cgroup/memory/user/rattila/1/lxc/lub8 nincs csatolva umount: /usr/lib/x86_64-linux-gnu/lxc/sys/fs/cgroup/perf_event/user/1000.user/c4.session/lxc/lub8 nincs csatolva umount: /usr/lib/x86_64-linux-gnu/lxc/sys/fs/cgroup/systemd/user/1000.user/c4.session/lxc/lub8 nincs csatolva systemd 229 running in system mode.

Waiting for something. >From the above "[FAILED] Failed to start Raise network interfaces." is true because I haven't configured OVS for this container. Switching off lub8 (finishing the freezing): rattila@fcubi:~/.local/share/lxc/lub8$ lxc-stop -n lub8 lxc-stop: monitor.c: lxc_monitor_read_fdset: 244 No such file or directory - client failed to recv (monitord died?) No such file or directory rattila@fcubi:~/.local/share/lxc/lub8$ Other problem: >From the config file for lub8: # Network configuration lxc.network.type = veth lxc.network.link = vbr0 lxc.network.veth.pair = veth-lub8 lxc.network.flags = up There isn't veth-lub8 interface on host. Instead of this there is the generated Ethernet interface which will be renamed every time when I (re)start lub8: vethSIIWU5 Link encap:Ethernet HWaddr fe:db:7d:ba:17:5a For OVS config I need permanent interface name! Can I solve these problems? TIA, Ruzsi
