Hi Peter,

Can anyone confirm this?

Yes. Check out:

http://www.13thfloor.at/vserver/s_release/v1.28/patch-2.4.27-rc2-vs1.28.diff

I don't see anything in the mailing list or
kernel changelogs.  E.g.,
http://www.kernel.org/pub/linux/kernel/v2.4/testing/patch-2.4.27.log.

It's because VServer is not part of the official kernel ;).

Linux Virtual Server extends the Linux kernel to provide the ability to
run several virtual servers on a single host system. In contrast to
other virtualization attempts Linux Virtual Server uses a split-
userland architechture under a single kernel to optimize sharing of all
resources and reduce resource consumption overhead per VM to the
absolute minimum.
http://www.linux-vserver.org/

Check the URL again. It's also a very nice project except all the syscalls introduced ;).

Cheers,
Roberto Nibali, ratz
