IPv6 (2005.12.06 18:01:06)

We currently migrate to MediaWiki from our old installation, but not all content has been migrated yet. Take a look at the Wiki Team page for instructions how to help or browse through our new wiki at wiki.linux-vserver.org to find the information already migrated.

IPv6 support for guests in Linux Vserver is supported through experimental patches.

Bruno Premont has written a patch for vserver, and you can find the latest version here: http://homepage.internet.lu/brunop/vserver/

The steps for getting it working are:

• Download the latest patch (probably the one with the latest kernel version - the one I used was IPv6 patch against linux-2.6.16.20-vs-2.1.1-rc22)
• Download the appropriate kernel from kernel.org (e.g. 2.6.16.20 )
• Download the appropriate vserver patch from http://vserver.13thfloor.at/Experimental/ ( e.g. vs-2.1.1-rc22 )

• Untar the kernel.
• cd into it. patch -p1 <../path-to-vserver-patch
• patch -p1 <../path-to-ipv6-patch

You should get no errors or rejected hunks.

Check the menuconfig, and build your kernel and modules as normal. Reboot, and boot into the new kernel.

When your machine has rebooted, and your vservers are running sucessfully, you need to assign your v6 address to the guest.

• First, add it to the host. ifconfig eth0 add 2001::1/64
• Download chbind6 from http://daniel.hozac.com/vserver/chbind6.c
• Compile it thusly: gcc -lvserver -I/usr/src/linux/include -o chbind6 chbind6.c (assuming you have the linux symlink pointing to the kernel you just compiled)
• Add the IPv6 to your vserver: ./chbind6 -n <context-id> -a -6 2001::1/64

Then, duck into your vserver ( vserver name enter ), and see your v6 address there.
