[libvirt-users] Assigning IPv6 address to guest
Hello, I am trying to assign an IPv6 address to one of my guests. I followed the following guide, unsuccessfully: https://www.berrange.com/posts/2011/06/16/providing-ipv6-connectivity-to-vir... . I have the following config files: dumpxml of the guest `deb`: http://sprunge.us/iUef net-dumpxml of network `default`: http://sprunge.us/WTfH net-dumpxml of network `ip6`: http://sprunge.us/YEXc Host: ifconfig: http://sprunge.us/cJOg Routing table: IPv6: http://sprunge.us/GChZ IPv4: http://sprunge.us/dACN /etc/network/interfaces: http://sprunge.us/fHcf /var/lib/libvirt/radvd/ip6-radvd.conf: http://sprunge.us/JcfF ip6tables: http://sprunge.us/JGBG uname -a: http://sprunge.us/acFF Guest: ifconfig: http://sprunge.us/JIFN Routing table: IPv6: http://sprunge.us/ZPfT IPv4: http://sprunge.us/gbXA /etc/network/interfaces: http://sprunge.us/ZaBB uname -a: http://sprunge.us/CFFL Both machines are running Debian Wheezy. virsh version is 0.9.12.3. The IP address I'm trying to assign to the guest is "2607:5300:60:1156::2/64". Forgive me if I'm making some trivial mistake, but this is more or less the first time I'm productively using IPv6. Thanks

I assume you are using two different IPV6 address for the two machines. I gave a quick scan of your mail but could not find what exactly is the issue you are facing ? Are you not able to ping ? Is the IP not getting assigned ? Are you able to ping link-local addresses ? what does this command output look like ? ip -6 nei

Hi, Your setup shows virbr2 and br0 both on the same network 2607:5300:60:1156::2/64 which will cause issues with routing. This however must not affect the pinging of link-local addresses ON the virtual machine: ping -I <eth0> <link-local of server> must work. If not check both side link-local addresses if they are set. A quick way to check with "any-body on the segment please reply" is to on virtual machine ping6 -I <eth0> ff02::1 You must see 2 addresses (one is your own link-local and the other is the address on the server) Example in my case is pasted (there are 4 machines): $ ping6 -I n1 ff02::1 PING ff02::1(ff02::1) from fe80::2c3b:53ff:fea0:9d26 n1: 56 data bytes 64 bytes from fe80::2c3b:53ff:fea0:9d26: icmp_seq=1 ttl=64 time=0.099 ms 64 bytes from fe80::c4a2:78ff:fe7d:af8d: icmp_seq=1 ttl=64 time=0.590 ms (DUP!) 64 bytes from fe80::5054:ff:fe12:3456: icmp_seq=1 ttl=64 time=0.967 ms (DUP!) 64 bytes from fe80::5054:ff:fe12:3457: icmp_seq=1 ttl=64 time=2.10 ms (DUP!) 64 bytes from fe80::2c3b:53ff:fea0:9d26: icmp_seq=2 ttl=64 time=0.097 ms 64 bytes from fe80::c4a2:78ff:fe7d:af8d: icmp_seq=2 ttl=64 time=0.318 ms (DUP!) 64 bytes from fe80::5054:ff:fe12:3456: icmp_seq=2 ttl=64 time=0.701 ms (DUP!) 64 bytes from fe80::5054:ff:fe12:3457: icmp_seq=2 ttl=64 time=1.06 ms (DUP!) ^C --- ff02::1 ping statistics --- 2 packets transmitted, 2 received, +6 duplicates, 0% packet loss, time 1001ms If link-local address cannot be ping-ed then try pinging ::1.

Hi,

ON the virtual machine: ping -I <eth0> <link-local of server> must work. If not check both side link-local addresses if they are set.
A quick way to check with "any-body on the segment please reply" is to on virtual machine ping6 -I <eth0> ff02::1 You must see 2 addresses (one is your own link-local and the other is the address on the server)
Example in my case is pasted (there are 4 machines):
$ ping6 -I n1 ff02::1 PING ff02::1(ff02::1) from fe80::2c3b:53ff:fea0:9d26 n1: 56 data bytes 64 bytes from fe80::2c3b:53ff:fea0:9d26: icmp_seq=1 ttl=64 time=0.099 ms 64 bytes from fe80::c4a2:78ff:fe7d:af8d: icmp_seq=1 ttl=64 time=0.590 ms (DUP!) 64 bytes from fe80::5054:ff:fe12:3456: icmp_seq=1 ttl=64 time=0.967 ms (DUP!) 64 bytes from fe80::5054:ff:fe12:3457: icmp_seq=1 ttl=64 time=2.10 ms (DUP!) 64 bytes from fe80::2c3b:53ff:fea0:9d26: icmp_seq=2 ttl=64 time=0.097 ms 64 bytes from fe80::c4a2:78ff:fe7d:af8d: icmp_seq=2 ttl=64 time=0.318 ms (DUP!) 64 bytes from fe80::5054:ff:fe12:3456: icmp_seq=2 ttl=64 time=0.701 ms (DUP!) 64 bytes from fe80::5054:ff:fe12:3457: icmp_seq=2 ttl=64 time=1.06 ms (DUP!) ^C --- ff02::1 ping statistics --- 2 packets transmitted, 2 received, +6 duplicates, 0% packet loss, time 1001ms
If link-local address cannot be ping-ed then try pinging ::1.
Pinging link-local address via `ping6 -I eth1 fe80::5054:ff:fe1d:a4bb` works now. Could you elaborate on virbr2 and br0 being on the same network please? As per the networking rules, there can be only one network segment on a given device. i.e there must not be a ambiguity on which interface to take to reach a network. This is the exact same rules which apply to an IPV4 network.
Now that the link-local addresses can be ping-ed, these addresses can be used to route packets to outside of the VM. The IP on the VMs must be 2 different IPs and the 3rd common IP (say 2607:5300:60:1156::3/64 ) can be assigned to either br0 or virbr0 whichever is common bridge to both the VMs. Once this is achieved then you will start seeing packets going through fine. Because if I'm seeing this correctly, br0 has
`2607:5300:60:1156::1/64` and virbr2 has `2607:5300:60:1156::2/64` and those are two completely different addresses, right?
They indeed are 2 different IPs but they belong to the same subnet. So the machine is confused on which interface to use when it has to reach a host on a network (there are some very complicated redundant link networks which use this kind of networking but I guess what we are discussing does not fall under this) May be this will help: http://www.youtube.com/watch?v=EkNq4TrHP_U
