there is a trampoline script which can do this:

as specific tool, no

maybe, at least it sounds interesting ...

well, no idea about the debian packages, on mandrake
the package is called util-vserver-devel, and it
basically provides the lib (libvserver.a/so) and a
single include file (/usr/include/vserver.h)

you might want to have a look at the vcmd source too,
although that is a hack tool for testing, but it is
able to generate any kernel syscall command used for
Linux-VServer, and it is supposed to work on all
platforms ...
