hi regarding the Linux containers

[Harini Donthineni]

hi ,
I have few queries in this area,can u pls help me ?

I am trying to create virtual router using test Linux kernel code 3.8

so my question is

looks like this can be done by container concept.various approaches are

lxc containers,openvz which ur discussing.



so my question is only using the Linux kernel src code can i develop a
virtual router sample program with out using Openvz like using setns and
netns .


is netns supported by Linux kernel latest ?


do i need to exclusively download and incorporate the patches ?

can u pls let me where can i get the documentation with sample examples for
the same.

Thanks & Regards

netns has been supported for quite some time in the kernel, as has
setns() to netns.  You don't need to apply any patches.  For
documentation see the manpages: setns(2), unshare(2), clone(2), and
finally the still-in-development namespaces(7), for which you can
see an early draft at https://lkml.org/lkml/2013/3/15/56

A virtual router can mean a lot of things to different folks, but I
would recommend playing with ip(8) aka iproute2.  The ip netns family of
commands allow you to configure the most common definitions of a virtual
router.
