在linux下配置ipv6 互通libvirt

First make sure you have two hosts installed with libvirt, qemu and virt-

manager

首先，确保安装libvirt，qemu，virt-manage等包

首先配置ipv6 

#ip6tables -F

#service libvirtd restart

**on client**

1 configure ipv6 global addr

ifconfig eth0 inet6 add 2004:db8:ac10:fe01::2/64

2 configure server/client ipv6 hostname resolvation

add the following line into /etc/hosts

**2004:db8:ac10:fe01::3 server's hostname**

**2004:db8:ac10:fe01::2 client's hostname**

**on server**

3 configure ipv6 global addr

ifconfig eth0 inet6 add 2004:db8:ac10:fe01::3/64

4. make sure the value of "auth_tcp" in "libvirtd.conf" is "none" 

5. disable "listen_tls" and enable "listen_tcp" in "libvirtd.conf"

6.Enable LIBVIRTD_ARGS="--listen" in /etc/sysconfig/libvirtd

7. configure server/client ipv6 hostname resolvation

add the following line into /etc/hosts

**2004:db8:ac10:fe01::3 server's hostname**

**2004:db8:ac10:fe01::2 client's hostname**

使用ping6 命令验证网络是否互通

8. Restart libvirtd service

# service libvirtd restart

9.prepare a running guest and **make sure its graphic device is listening to
