Frank, First let me make a disclaimer: I don't have much experience with virtualization, but I do have some. That experience is a bit rusty. I don't have much experience with cobbler, but I do have some. That experience, too, is rusty. And I'm accordingly rusty with networking as it applies to virtual machines. A little reading tonight has helped me understand more about that. With all that said, I think I can give you a pretty good analogy that makes your goal easier to understand.
Let's imagine you are in New Jersey at Hazard's Dock in the year 1870 and you look across the Hudson River towards New York. You realize that day that one can save a lot of time in going to and from New York if only there were a bridge across the river there that pedestrians, horses, and railroad traffic could use, and ships could still pass under. Well, the VPS ethernet connection is like Hazard's Dock that year: real busy, but no packets are getting to New York yet. Think of the landing point in New York as the ethernet connection of the physical host computer. No packets from that are getting to New Jersey, either. They are waiting for a bridge so they can cross and there can be two way traffic over the river. You want to allow ethernet traffic to pass between the host computer's physical ethernet adapter and your virtual adapter on the VPS. That will let networking happen. That in turn will let DHCP services happen. Now the person who made the post you are referencing on the OpenVz forums is talking specifically about a CentOS 5.2 kernel. The CentOS kernels are all based on Red Hat Enterprise Linux versions. So the kernels are all generically "Red Hat" kernels. The poster for that checked the Red Hat Enterprise Linux documentation for building an ethernet "bridge" adapter between the VPS and the physical ethernet adapter on the physical host computer (eth0). Red Hat has loads of documentation for their Red Hat Enterprise Linux product; and CentOS points to it on their website at http://www.centos.org/ Is your host kernel a Red Hat-produced kernel? If not, you will have to consult the documentation for your specific host kernel for how to build a bridge ethernet adapter. That is one of the issues here, I think. So, what kernel are you running on your host computer? And what kernel are you running for your VPS? With a bit of study of the documentation for these kernels, you should be able to code and test a network bridge between the two.
