Would you please clarify? Thanks! Shixiong Hello, I'm not an expert ;-) but i use libvirt and i had problem with dhcpv6 by default the dhcp clients use duid-llt begining with 00:01:00:01 My solution (because libvirt doesn't accept mac adresse in ipv6 host) is to impose use of dibbler-client with in /etc/dibbler/client.conf: #modifications inactive-mode strict-rfc-no-routing duid-type duid-ll the dhcp-hostfile generated by libvirt is : root@root:~# more /var/lib/libvirt/dnsmasq/default-ipv6.hostsfile 52:54:00:4b:c2:02,192.168.122.2,vm1 52:54:00:4b:c2:03,192.168.122.3,vm2 52:54:00:4b:c2:04,192.168.122.4,vm3 52:54:00:4b:c2:05,192.168.122.5,vm4 52:54:00:4b:c2:06,192.168.122.6,vm5 52:54:00:4b:c2:07,192.168.122.7,vm6 52:54:00:4b:c2:08,192.168.122.8,vm7 52:54:00:4b:c2:09,192.168.122.9,vm8 id:00:03:00:01:52:54:00:4b:c2:02,vm1,[2a00:c70:1:xx:xx:xx:xx:101] id:00:03:00:01:52:54:00:4b:c2:03,vm2,[2a00:c70:1:xx:xx:xx:xx:201] cheers Bertrand ___ Dnsmasq-discuss mailing list Dnsmasq-discuss@lists.thekelleys.org.uk http://lists.thekelleys.org.uk/mailman/listinfo/dnsmasq-discuss
