Proxmox KVM - Reach VNC in IPv6

These days, I am playing with Proxmox, a free and open-source Linux distribution which provides an easy solution for virtualization. In fact, they include:

• a linux kernel with KVM (full virtualization) and OpenVZ (containers)
• an interface to manage kvm, openvz, storage, backups and also monitoring

You can create, start, stop your virtual machines or containers via the web interface. For a KVM, they even provide a VNC java applet to see the screen of your virtual machine. This is amazing!

IPv6 NDP Proxy

A few days ago, I wrote an article about IPv6 NDP Proxy for a blog that I love to read. The problem discussed is that some routers who provide you an IPv6 prefix want to see the IPv6 addresses on the same L2 segment, so you can't use routing directly.

This problem can be encountered at OVH - an European dedicated server provider - if you want to set up virtual machines with IPv6 routing; or, if you have a Freebox - the set-top box provided by Free.fr provider - and want to use your own router behind.

In the article, I explain a solution based on the use of the NDP Proxy included in the linux kernel, with the example of a dedicated server at OVH.
