结果谷歌一系列的查找资料，最后还是到了hetzner的wiki找到了解决办法。

1.proxmox桥接网卡配置：

# /etc/network/interfaces
### Hetzner Online GmbH - installimage
# Loopback device:
auto lo
iface lo inet loopback
#
# device: eth0
auto  eth0
iface eth0 inet static
       address   <Main IP>
       netmask   255.255.255.255
       pointopoint   <Gateway>
       gateway   <Gateway>
#
iface eth0 inet6 static
       address   <Address from the IPv6 Subnet> #eg: 2001:db8::2
       netmask   128
       gateway   fe80::1
       up sysctl -p
# for single IPs
auto vmbr0
iface vmbr0 inet static
        address  10.0.1.1
        netmask  255.255.255.0
        bridge_ports none
        bridge_stp off
        bridge_fd 0
#
iface vmbr0 inet6 static
       address   <Address from the IPv6 Subnet> #eg: 2001:db8::2
       netmask   64

关于Nat链接网络请使用iptables实现。

2.solusvm下网卡配置：

主网卡中默认配置请不要修改，仅需将IPV6ADDR的/64换为/128
例如：IPV6ADDR= 2001:db8::2/128
然后将桥接网卡更改为：

DEVICE=br0
ONBOOT=yes
TYPE=Bridge
BOOTPROTO=static
IPADDR=10.0.1.1
NETMASK=255.255.255.0
IPV6ADDR=2001:db8::2/64

关于联网与端口映射请使用iptables

3.关于虚拟机（kvm）的配置：

这里拿2001:db8::此ipv6做示范
Debian or Ubuntu：

iface eth0 inet6 static
       address    2001:db8::f001
       netmask   64
       gateway   2001:db8::2

Centos:

IPV6INIT=yes
IPV6ADDR=2001:db8::f001/64
IPV6_DEFAULTGW=2001:db8::2
