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

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@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
