[ovirt-users] ipv6 in guests not worknig

[Peter Hudec]

Hi,

maybe there was some similar problem in past, but I haven't found any
solution for this.

I want to user IPv6 in our guest but it's not working.

When I try to ping the guest from out side world I see on the ovirt node
(3.5) following:

[root at dipovirt01 ~]# brctl show servers_dmz
bridge name    bridge id        STP enabled    interfaces
servers_dmz        8000.00269e02b640    no        bond0.30
                            vnet0

[root at dipovirt01 ~]# tcpdump -i bond0.30 -n icmp6
tcpdump: WARNING: bond0.30: no IPv4 address assigned
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on bond0.30, link-type EN10MB (Ethernet), capture size 65535 bytes

[root at dipovirt01 ~]# tcpdump -i servers_dmz -n icmp6
tcpdump: WARNING: servers_dmz: no IPv4 address assigned

09:32:45.683960 IP6 2a02:6300:0:21e::1 > ff02::1:ff00:b: ICMP6, neighbor
solicitation, who has 2a02:6300:0:21e::b, length 32


[root at dipovirt01 ~]# tcpdump -i vnet0 -n icmp6
tcpdump: WARNING: vnet0: no IPv4 address assigned
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on vnet0, link-type EN10MB (Ethernet), capture size 65535 bytes


On the vnet0 interface I do not see any IPv6 ICMP ND packets, so in the
virtual machine.
I allowed IPv6 forwarding in sysctl and rebooted the node /to be sure/

[root at dipovirt01 ~]# cat /etc/sysctl.d/ipv6.conf
net.ipv6.conf.all.forwarding = 1
net.ipv6.conf.default.forwarding = 1

Any suggestion what's wrong?

    bets regards
        Peter
