KVM Ubuntu Guest IPV6 DHCP не работает

Question

KVM Ubuntu Guest IPV6 DHCP не работает

У меня есть сервер KVM, сидящий на сервере Debian.

Настройка сети через модель устройства Macvtap/ Bridge rtl8139

Я установил Ubuntu Server 18.10 без X.

/etc/netplan/50-cloud-init.yaml
network:
    version: 2
    ethernets:
        ens3:
            addresses:
            - 192.168.1.236/24
            dhcp4: false
            dhcp6: true
            gateway4: 192.168.1.1
            nameservers:
                addresses:
                - 1.1.1.1
                - 8.8.8.8
                - 8.8.4.4
                search:
                - jlbprof.com

IPV4 работает отлично, я могу пинговать мир, но ipv6 не так много

Здесь я могу пинговать шлюз настройки

У меня есть другие настройки VM, которые отлично работают, если я ничего не делаю с конфигом (где все по умолчанию, я полагаю, dhcp4 и 6), но netplan в основном и пустой файл.

Что не так с моей настройкой IPV6?
