Hi All, A new version of the liblxc has been released, lxc-0.6.0. This version provides a new set of features: * take into account the devpts new instance * we can log to the container with the tty, lxc-console * we can use a directory or a block device as a rootfs * lxc-debian script build a lenny debian * various fix and improvement One important information: ========================== *** lxc will no longer need a patched kernel, all the kernel features are available in the 2.6.29 kernel *** Thanks for the contributions and the feedbacks. Below a detailed log of the modifications: 2009-02-20 15:13 dlezcano * scripts/lxc-debian.in: Add the pts configuration for lxc-debian From: Daniel Lezcano <dlezcano@xxxxxxxxxx> Add the pts configuration when creating a debian container. Signed-off-by: Daniel Lezcano <dlezcano@xxxxxxxxxx> 2009-02-16 12:25 dlezcano * src/lxc/: parse.c, parse.h: Add missing files to CVS 2009-02-16 11:22 dlezcano * src/lxc/: Makefile.am, lxc_conf.c, lxc_config.c, lxc_unshare.c: Factor out some code From: Daniel Lezcano <daniel.lezcano@xxxxxxx> Factor out some code and especially the parsing of text file functions. Signed-off-by: Daniel Lezcano <dlezcano@xxxxxxxxxx> 2009-02-16 11:21 dlezcano * src/lxc/lxc_conf.c: Support block device for the rootfs From: Daniel Lezcano <dlezcano@xxxxxxxxxx> Allow to specify a block device as the rootfs. The creation of the container will try with brute force to determine the file system type. Signed-off-by: Daniel Lezcano <dlezcano@xxxxxxxxxx> 2009-02-16 11:19 dlezcano * lxc.spec.in, src/lxc/Makefile.am: Add more capabilities From: Daniel Lezcano <daniel.lezcano@xxxxxxx> lxc-execute and lxc-create need capability to mount. Signed-off-by: Daniel Lezcano <dlezcano@xxxxxxxxxx> 2009-02-16 11:14 dlezcano * src/lxc/lxc_conf.c: Make use of realpath From: Daniel Lezcano <daniel.lezcano@xxxxxxx> The realpath function is more convenient to build the absolute path of the rootfs. Signed-off-by: Daniel Lezcano <dlezcano@xxxxxxxxxx> 2009-02-16 11:13 dlezcano * src/lxc/lxc_conf.c: Mount bind the rootfs directory From: Daniel Lezcano <daniel.lezcano@xxxxxxx> Instead of using a symlink to the rootfs, just mount bind the rootfs directory. Signed-off-by: Daniel Lezcano <dlezcano@xxxxxxxxxx> 2009-02-16 11:11 dlezcano * scripts/lxc-debian.in: Remove some pointless debian services From: Daniel Lezcano <daniel.lezcano@xxxxxxx> Remove some debian services because they don't have sense in a container, like the hw clock or the unmount of the file systems. Signed-off-by: Daniel Lezcano <dlezcano@xxxxxxxxxx> 2009-02-12 15:48 dlezcano * doc/lxc.conf.sgml.in: Update the man according new devpts instance From: Daniel Lezcano <dlezcano@xxxxxxxxxx> Update the man page with the new devpts instance option. Signed-off-by: Daniel Lezcano <dlezcano@xxxxxxxxxx> 2009-02-12 15:48 dlezcano * src/lxc/lxc_conf.c: setup the new pts instance From: Daniel Lezcano <dlezcano@xxxxxxxxxx> The pts new instance is setup conforming the documentation in the kernel sources, Documentation/filesystems/devpts.txt. Signed-off-by: Daniel Lezcano <dlezcano@xxxxxxxxxx> 2009-02-12 15:47 dlezcano * src/lxc/: error.c, error.h, lxc_conf.c, lxc_conf.h, lxc_config.c: add the new pts instance configuration From: Daniel Lezcano <dlezcano@xxxxxxxxxx> This patch adds the configuration for a new pts instance. Signed-off-by: Daniel Lezcano <dlezcano@xxxxxxxxxx> 2009-02-12 15:47 dlezcano * src/lxc/lxc_conf.c: build a set of flags for the different enabled subsystems From: Daniel Lezcano <dlezcano@xxxxxxxxxx> When we want to check if a subsystem is enabled, we look at the presence of a file/directory in the configuration tree files. That works until we chroot into the rootfs. Some subsystem should be preferably setup after the chrootfs, making the code simpler and easier to read. So before setup the different subsystem, I build a flags set and reuse it later to check if the subsystem is enabled or not.

Signed-off-by: Daniel Lezcano <dlezcano@xxxxxxxxxx> 2009-02-09 18:11 dlezcano * scripts/lxc-debian.in: add missing ifupdown package to debootstrap From: Daniel Lezcano <dlezcano@xxxxxxxxxx> Add the ifupdown missing package. Signed-off-by: Daniel Lezcano <dlezcano@xxxxxxxxxx> 2009-02-09 18:10 dlezcano * scripts/lxc-debian.in: Update lxc-debian to use the lenny release From: Matt Helsley <matthltc@xxxxxxxxxx> With the release of lenny nearing this patch may soon be useful. Signed-off-by: Matt Helsley <matthltc@xxxxxxxxxx> Signed-off-by: Daniel Lezcano <dlezcano@xxxxxxxxxx> 2009-02-09 18:10 dlezcano * bootstrap: Create the m4 directory if it does not exist From: Daniel Lezcano <dlezcano@xxxxxxxxxx> Create the m4 directory if it does not exist Reported-by: Dietmar Maurer <dietmar@xxxxxxxxxxx> Signed-off-by: Daniel Lezcano <dlezcano@xxxxxxxxxx> 2009-02-05 13:03 dlezcano * scripts/lxc-debian.in: handle interruption/failure of lxc-debian more gracefully From: Matt Helsley <matthltc@xxxxxxxxxx> If lxc-debian fails or is interrupted during debootstrap then the next invocation of lxc-debian breaks because it only checks for the existence of the directory. This forces the user to remove the cache by hand to retry the create step. Let's allow the user to re-run lxc-debian to resume/retry. Store the cache in a partial-$ARCH directory until debootstrap succeeds. Then move the valid cache to its final destination.

We want to use this debian version with a newer kernel. This patch gives the signalfd function prototype, because the function is available in the glibc-2.7 which is the version coming with debian Lenny. Signed-off-by: Dietmar Maurer <dietmar@xxxxxxxxxxx> Signed-off-by: Daniel Lezcano <dlezcano@xxxxxxxxxx> 2009-01-29 11:50 dlezcano * scripts/lxc-debian.in: Complete use of autoconf prefix in lxc-debian From: Matt Helsley <matthltc@xxxxxxxxxx> The lxc-debian script does not consistently address the lxc lock as @LOCALSTATEDIR@/lock/subsys/lxc. Make consistent use of the autotools substitution to completely enable configure --prefixes. I also added a comment explaining why some of the paths didn't need autoconf substitutions for anyone who wants to understand the script. Also, to separate it from the container contents proper, I moved the CACHE variable initialization above the container-internal path variables.

On the powerpc architecture, that leads to an infinite loop in the getopt inspection because getopt returns 255 instead of -1 as expected. The opt variable should be an int and not a char.

Until this version the network devices have to be destroyed by lxc. This modification checks the version of the kernel to make lxc to destroy the network devices or not.

At this point, we are able in the container to add the ttys in the inittab file. The configuration should specify how many tty we want in the container. Rights are not yet supported - anyone can use the tty of any container. Resizing of the tty is not supported - and probably won't be.
