Hi,<br>
<br>
maybe there was some similar problem in past, but I haven't found
any solution for this.<br>
<br>
I want to user IPv6 in our guest but it's not working.<br>
<br>
When I try to ping the guest from out side world I see on the ovirt
node (3.5) following:<br>
<br>
[root@dipovirt01 ~]# brctl show servers_dmz<br>
bridge name bridge id STP enabled interfaces<br>
servers_dmz 8000.00269e02b640 no bond0.30<br>
vnet0<br>
<br>
[root@dipovirt01 ~]# tcpdump -i bond0.30 -n icmp6<br>
tcpdump: WARNING: bond0.30: no IPv4 address assigned<br>
tcpdump: verbose output suppressed, use -v or -vv for full protocol
decode<br>
listening on bond0.30, link-type EN10MB (Ethernet), capture size
65535 bytes<br>

<br>
[root@dipovirt01 ~]# tcpdump -i servers_dmz -n icmp6<br>

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<br>
<br>
<br>
[root@dipovirt01 ~]# tcpdump -i vnet0 -n icmp6<br>
tcpdump: WARNING: vnet0: no IPv4 address assigned<br>
tcpdump: verbose output suppressed, use -v or -vv for full protocol
decode<br>
listening on vnet0, link-type EN10MB (Ethernet), capture size 65535
bytes<br>
<br>
<br>
On the vnet0 interface I do not see any IPv6 ICMP ND packets, so in
the virtual machine.<br>
I allowed IPv6 forwarding in sysctl and rebooted the node /to be
sure/<br>
<br>
[root@dipovirt01 ~]# cat /etc/sysctl.d/ipv6.conf <br>
net.ipv6.conf.all.forwarding = 1<br>
net.ipv6.conf.default.forwarding = 1<br>
<br>
Any suggestion what's wrong?<br>
<br>
bets regards<br>
Peter<br>
