[lxc-devel] A few fixes for lxc-fedora template
Hi, I was setting up a Fedora container on my Ubuntu 11.10 system, but ran into some problems with the lxc-fedora template. I tried with the latest version from the git master, but it also needed some small fixes to get it working. So here are the fixes that I did. Hopefully someone else also finds these useful. -- Tuomas Suutari -- The demand for IT networking professionals continues to grow, and the demand for specialized networking skills is growing even more rapidly.

[lxc-devel] [PATCH 3/3] lxc-fedora.in: Fix fetching of the fedora-release rpm
The hardcoded URL seems to be broken and 404 error was not checked. Now the mirror is selected from mirrorlist (instead of hardcoding to funet.fi) and fetch errors are checked. Also added a retry loop (with 3 tries) to find a working mirror, since some of the mirrors are not OK.

[lxc-devel] [PATCH 0/3] The poor man's attach
Often people want to launch a command in an already running container. This can be achieved with the lxc-attach command, provided you have a patched kernel with full setns() support. For those who won't rebuild a kernel, we introduce the lxc-rexec command to be used in place of lxc-attach. The principle is to embed a minimal unix socket server in lxc-init that launch commands when asked to by a lxc-rexec client. For the moment, this feature only works for application containers started with lxc-execute. Some more work would be needed to have something similar for system containers (and by the way, system containers with network support may rely on rsh-like services to do the trick). The first two patches add a mainloop and logging features to lxc-init, and the last patch brings lxc-rexec. --- Greg Kurz (3): lxc: introduce lxc-rexec lxc-init: use lxc logging infrastructure lxc-init: use lxc_mainloop configure.ac |1 doc/Makefile.am |1 doc/lxc-rexec.sgml.in | 151 ++ src/lxc/Makefile.am |7 - src/lxc/arguments.h |3 src/lxc/error.c | 23 ++ src/lxc/error.h |3 src/lxc/execute.c | 66 ++ src/lxc/execute.h | 28 +++ src/lxc/lxc.h |1 src/lxc/lxc_execute.c |3 src/lxc/lxc_init.c| 511 ++--- src/lxc/lxc_rexec.c | 337 13 files changed, 1014 insertions(+), 121 deletions(-) create mode 100644 doc/lxc-rexec.sgml.in create mode 100644 src/lxc/execute.h create mode 100644 src/lxc/lxc_rexec.c -- Greg -- The demand for IT networking professionals continues to grow, and the demand for specialized networking skills is growing even more rapidly.

[lxc-devel] [PATCH 1/3] lxc-init: use lxc_mainloop
The goal here is to be able to multiplex several event sources in
lxc-init. It will be a lot easier to add I/O driven features: for
example, a rexec-like service to start extra commands in a
container.

[lxc-devel] [PATCH 3/3] lxc: introduce lxc-rexec
The lxc-rexec command connects to the lxc-init process on an
AF_UNIX socket to spawn commands inside the container. Signals
are forwarded from lxc-rexec to the command and the exit code
is sent back to lxc-rexec. The command also runs in its own
session with its own ctty.
Multiple commands can be attached to the container.
Caveats :
- environment and current dir is not propagated
- the container exits only when the last attached command dies
- attachement between containers is possible

+
+ lxc-rexec runs the specified

+
+
+
+ The lxc-rexec command is to be used with
+ application containers, started by
+ the lxc-execute
+ command. lxc-execute spawns a custom init
+ process lxc-init which is also used to exec
+ processes inside the container. The launched process is
+ reparented to lxc-init, as a daemon.
+
+
+ The lxc-rexec command forwards received
+ signals to the command running inside the container and returns
+ its exit code with it dies.
+
+
+
+
+Options
+
+
+
+ --
+
+
+ Signal the end of options and disables further option
+ processing. Any arguments after the -- are treated as

[lxc-devel] [lxc-dev]how to use lxc directly in kernel
Hi I am a newbie to Linux container. Recently,I decide to using lxc derectly on linux kernel,but find it hard to install. (so far as I know,lxc tools is based on GUI Linux distribution). Anyone has this experience? or give me a hint on how to use the lxc directly on linux kernel without the lxc tools?
