[ANNOUNCE] second stable release of Linux-VServer

[ANNOUNCE] second stable release of Linux-VServer

[Herbert Poetzl]

Well, as the OpenVZ folks announced their release on LKML
I just decided to do similar for the Linux-VServer release,
so please let me know if that is not considered appropriate.

Short Overview:

Linux-VServer, a soft partitioning concept based on Contexts
(Process, Network and Filesystem Isolation) which permits
the creation of many independent Virtual Private Servers (VPS)
that run simultaneously on a single physical server at full
speed, efficiently sharing hardware resources.

A VPS provides an almost identical operating environment as
a conventional Linux Server. All services, such as ssh, mail,
Web and databases, can be started on such a VPS, without
(or in special cases with only minimal) modification, just
like on any real server.

The Project is following the kernel development very closely,
and provides Stable as well as Development patches for 2.6
and 2.4 vanilla kernels.

(more details can be found at http://linux-vserver.org/)

The patch is available here:
http://www.13thfloor.at/vserver/s_rel26/v2.01/

For the lkml folks, the broken out version of the patch
is probably most interesting (if there is some detailed
interest, I'll comment on the patches ...)

http://www.13thfloor.at/vserver/s_rel26/v2.01/split-2.6.14.3-vs2.01.tar.bz2
(IMHO too huge to attach them inline)

best,
Herbert

Since there is a legitimate (and very popular) use case for
virtuozzo / vserver functionality, I think it is a good
thing to get all the code out in the open.

I really hope we will get something like BSD jail functionality
in the Linux kernel.  It makes perfect sense for hosting
environments.

Well a version for 2.6.15-rc2 is still at sf.net/projects/linuxjail.  I
haven't resubmitted to lkml in a long time because I haven't found or
implemented a better solution for the network virtualization, which
Christoph wasn't happy with.  The vserver ngnet or openvz networking may
be a good solution.  Additionally, the pid virtualization we've been
discussing (and which should be submitted soon) would remove the need
for the tasklookup patch, so bsdjail would reduce even further, to
network and simple access controls.

Note that I would prefer to see the full vserver in the kernel...

complete pid virtualization would be interesting for
migration and checkpointing too (not just isolation
and security), so I think that might be something of
interest for a broader audience ...

Just to make sure everybody is aware:
pids are already virtualized in OpenVZ.
If you want to look at the code, it is available
from within diff-openvz-ve patch, see
http://ftp.openvz.org/kernel/broken-out/022stab053.1/

Serge, Kir,

would be great if you both could provide a broken
out version of the pid virtualization for discussion

TIA,
Herbert

Like many needs there are lots of solutions, none of which are perfect, 
or at least without problems the competition says are important ;-) This 
is one more thing to study, but it seems as though there is not an 
overview of the various solutions for easy comparison.

This list is probably incomplete:
  linuxjail - BSD jail is the goal
  VMware - I use this for BSD machines
  xen - the last I looked ran Linux, not Windows or BSD unpatched
  UML - run Linux nicely
  VServer - news to me
