网络

更改kvm的网络模式

由于kvm的网络模式默认是nat的，可以参照如下方法修改为bridge模式：

[root@bogon ~]#cd /etc/sysconfig/network-scripts/
[root@bogon ~]# cp ifcfg-eth0 ifcfg-br0
[root@bogon ~]# cat /etc/sysconfig/network-scripts/ifcfg-br0 
DEVICE=br0
TYPE=Bridge
BOOTPROTO=static
ONBOOT=yes
NM_CONTROLLED=no
IPADDR=192.168.1.20
NETMASK=255.255.255.0
GATEWAY=192.168.1.1
DNS1=114.114.114.114
[root@bogon ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0 
NAME=eth0
DEVICE=eth0
TYPE=Ethernet
BOOTPROTO=none
BRIDGE=br0
ONBOOT=yes
NM_CONTROLLED=no
[root@bogon ~]# systemctl restart network

删除NAT网络

# virsh net-destroy default
# virsh net-undefine default
# service libvirtd restart
