[Lxc-users] lxcbr0 versus virbr0 (Ubuntu)
Prologue: I run LXC successful for nearly 2 years on Ubuntu 10.04, using veth / br0. Every container has its own IP address, no NAT. I run production services like http://fex.rus.uni-stuttgart.de/ on it, rocksolid. I have now set up second server with Ubuntu 12.04 and there have changed a lot of things, starting with networking. Reading https://help.ubuntu.com/12.04/serverguide/lxc.html it says one can use lxcbr0 or virbr0 for bridging, but without further explanation. What is "better"? Or is lxcbr0 only for NAT? Is virbr0 the successor of br0? Probably I am missing some basic documentation... The new server has six GbE interfaces and I have set up "ethernet bonding": three real interfaces build one virtual interface. I have successfully assigned a single test-IP to bond1: root@vms3:~# route -n Kernel IP routing table Destination Gateway Genmask Flags Metric RefUse Iface 0.0.0.0 129.69.202.142 0.0.0.0 UG10000 bond0 10.0.3.00.0.0.0 255.255.255.0 U 0 00 lxcbr0 129.69.1.0 0.0.0.0 255.255.255.0 U 0 00 bond1 129.69.202.128 0.0.0.0 255.255.255.240 U 0 00 bond0 169.254.0.0 0.0.0.0 255.255.0.0 U 1000 00 bond0 (lxcbr0 was automaticaly started when I installed lxc) How shall I continue?

Is there a getty or login shell running on /dev/tty1 ?
Do you have /etc/init/tty*.conf ?

lxc-execute operates on a different container than lxc-start.
With lxc-execute you cannot start a programm (like useradd) inside a
already running container.
lxc-start is for booting a whole linux system while lxc-execute starts
only a single programm inside an isolated environment ("container" in lxc
terminolgy).
The lxc-execute man-page needs more explanation on this point.
If you want to execute a programm inside a running container, you have to
use ssh or my lxc script:
lxc -x containter useradd ...

At this point I gave up and tried the Windows problem solving methode: rebooting (the host server). After reboot, I can start and stop containers without any problems. Everything works fine, as it should.

[Lxc-users] Ubuntu /etc/init.d/xinetd kills container's xinetd
I have an Ubuntu LXC hosts with several containers running internet
services via xinetd.
Sometimes the container services died without any reason and no logfile
entry. First, I thought LXC is not that stable as I hoped, but now I
found the bug inside /etc/init.d/xinetd !
The problem is: when I stop xinetd on the host with command
"/etc/init.d/xinetd stop"
this stops all LXC container xinetd processes, too!
/etc/init.d/xinetd contains bad code which does not respect the xinetd
pidfile. See "man man start-stop-daemon":
Note: unless --pidfile is specified, start-stop-daemon behaves similar
to killall(1). start-stop-daemon will scan the process table looking
for any processes which match the process name (...)
The following patch prevents this unwanted behaviour:

Put: lxc.cap.drop = sys_module to your LXC container config file.
