Currently the Mageia ifup scripts do no support ipv6 properly. Network Manager does not work with tools that require bridges such as xen. Currently in Mageia 8 I'm using systemd-networkd instead in order to get ipv6 working without using Network Manager. $ cat /etc/systemd/network/10-eth0.network [Match] Name=eth0 [Network] Description=LAN_NIC DNS=::1 DNS=192.168.10.2 DNS=192.168.10.101 DNS=8.8.8.8 Domains=rp4.hodgins.homeip.net DHCP=no LLMNR=false IPv6AcceptRA=yes [Address] Address=192.168.10.101/16 [Route] Gateway=192.168.10.11 I think it would be good for Mageia to keep having an alternative to Network manager. It also supports bridging ... # cat /etc/systemd/network/xenbr.network [Match] Name=xenbr [Network] Description=LAN_NIC DNS=::1 DNS=127.0.0.1 DNS=8.8.8.8 Domains=x3.hodgins.homeip.net DHCP=yes LLMNR=false IPv6AcceptRA=yes [Address] Address=192.168.10.2/16 [Route] Gateway=192.168.10.11 #[DHCPV6]
