All,
We've been gathering, porting and testing a whole bunch of patchsets
related to namespaces, containers and resource management in what
we call the -lxc patchset.
The purpose of the -lxc patchset is to experiment and test a "fully"
featured linux container solution. this is a large topic but resource
management and container mobility are the main high level features we
are looking at.
We're not there yet but we've done a lot of progress in 2006 and early
2007. It seems a good time to share some this work and see :
* which patchsets can be proposed to andrew
* which patchsets requires more work
* which can be dropped
* what kind of cleanups are still required
* etc.
The latest release 2.6.20-lxc8 contains the following :
* user namespace from Serge E. Hallyn <[EMAIL PROTECTED]>
* bind_ns() syscalls from Cedric Le Goater <[EMAIL PROTECTED]>
* ro bind mount from Dave Hansen <[EMAIL PROTECTED]>
* generic Process containers from Paul Menage <[EMAIL PROTECTED]>
* namespace entering from Serge E. Hallyn <[EMAIL PROTECTED]>
* resource controllers based on process containers from Pavel Emelianov <[EMAIL
PROTECTED]>
* multiple /proc (required for pid namespace) from Dave Hansen <[EMAIL
PROTECTED]>
* pid namespace from Sukadev Bhattiprolu <[EMAIL PROTECTED]>
* L2 network namespace from Eric W. Biederman <[EMAIL PROTECTED]>
* misc fixes and cleanups from others (sorry for not mentioning)
and it's giving some good results on common platforms like i386 and
x86_64.
It's all here :
http://lxc.sourceforge.net/patches/2.6.20/2.6.20-lxc8
Some very basic user space tools to work and test namespaces can
also be found here :
http://lxc.sourceforge.net/patches/2.6.20/2.6.20-lxc8/broken-out/tests/
A lot of work still needs to be done in user space..this is not
the highest priority for the moment but sooner or later we'll
need to spend more time on it.
Hope you find it useful. If you have any issues with sourceforge
download, please tell me. I can move this patchset to a more
convenient site.
Cheers,
C.
