如何在 Vagrant 和 VirtualBox 中使用 ipv6？

Question

我有一个在 VirtualBox 中运行 Ubuntu 的 Vagrant 设置。我正在尝试创建一个可以从主机访问的公共虚拟网络接口。我用 ipv4 做这个没有问题。使用 ipv6 我将界面设置为：

guest$ ip link add derpcraft link eth1 type macvlan mode bridge;    
guest$ ip -6 addr add fdfe:dcba:9876:ffff::/64 dev derpcraft
guest$ ip link set derpcraft up

界面看起来像：

        derpcraft Link encap:Ethernet  HWaddr 26:22:d5:54:95:00  
                  inet6 addr: fe80::2422:d5ff:fe54:9500/64 Scope:Link
                  inet6 addr: fdfe:dcba:9876:ffff::/64 Scope:Global
                  UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
                  RX packets:264 errors:0 dropped:0 overruns:0 frame:0
                  TX packets:24 errors:0 dropped:0 overruns:0 carrier:0
                  collisions:0 txqueuelen:0 
                  RX bytes:52989 (52.9 KB)  TX bytes:2040 (2.0 KB)

从主机上，我似乎无法在接口上 ping 这个地址。

host$ ping6 fe80::2422:d5ff:fe54:9500
ping6: UDP connect: No route to host
host$ ping6 fe80::2422:d5ff:fe54:9500%::1
ping6: UDP connect: No route to host
host$ ping6 fdfe:dcba:9876:ffff::
ping6: UDP connect: No route to host
host$ ping6 fdfe:dcba:9876:ffff::%::1
ping6: UDP connect: No route to host

我想我可能需要配置 Vagrant 或 VirtualBox 以接受 ipv6 连接。

还有一点。我目前的 ISP 还不是 ipv6 友好的。我不怀疑这与它有任何关系，因为这都应该是本地请求。

更新：为了更好的衡量，我给了接口一个 ipv4 地址，如：

guest$ ip address add 192.168.33.11/24 broadcast 192.168.33.255 dev derpcraft
guest$ ifconfig
derpcraft Link encap:Ethernet  HWaddr 26:22:d5:54:95:00  
          inet addr:192.168.33.11  Bcast:192.168.33.255  Mask:255.255.255.0
          inet6 addr: fe80::2422:d5ff:fe54:9500/64 Scope:Link
          inet6 addr: fdfe:dcba:9876:ffff::/64 Scope:Global
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:1736 errors:0 dropped:0 overruns:0 frame:0
          TX packets:24 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:418224 (418.2 KB)  TX bytes:2040 (2.0 KB)

我可以从主机 ping 没问题：

host$ ping 192.168.33.11
PING 192.168.33.11 (192.168.33.11): 56 data bytes

更新：主机界面如下所示：

host$ ifconfig
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
    options=3<RXCSUM,TXCSUM>
    inet6 fe80::1%lo0 prefixlen 64 scopeid 0x1 
    inet 127.0.0.1 netmask 0xff000000 
    inet6 ::1 prefixlen 128

    inet 192.168.1.72 netmask 0xffffff00 broadcast 192.168.1.255
    media: autoselect
    status: active

vboxnet1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
    ether 0a:00:27:00:00:01 
    inet 192.168.33.1 netmask 0xffffff00 broadcast 192.168.33.255

这表明 VirtualBox 接口都没有 inet6，这可能是问题所在，但我不确定如何启用它。

看起来使用 vagrantspublic_network选项会将 virtualbox 接口桥接到支持 IPV6 的主机接口
