创建虚拟网络

  添加子接口

[root@localhost network-scripts]# vi ifcfg-eth1.110

DEVICE=eth1.110
HWADDR=E4:1F:13:62:2B:1E
NM_CONTROLLED=yes
ONBOOT=yes
BOOTPROTO=static
TYPE=Ethernet
IPV6INIT=no
USERCTL=no
VLAN=yes
IPADDR=1.1.1.34
NETMASK=255.255.255.0

 

[root@localhost network-scripts]# vi ifcfg-eth1.20

DEVICE=eth1.20
HWADDR=E4:1F:13:62:2B:1E
NM_CONTROLLED=yes
ONBOOT=yes
BOOTPROTO=static
TYPE=Ethernet
IPV6INIT=no
USERCTL=no

增加网桥

brctl addbr br110
brctl addbr br20

brctl addif br110 eth1.110
brctl addif br20 eth1.20

增加虚拟机硬盘

 

mkdir -p /vm/vm1
mkdir -p /vm/vm2
mkdir -p /vm/vm3
mkdir -p /vm/vm4
mkdir -p /vm/images

qemu-img create /vm/vm1/vm1.img  70G
qemu-img create /vm/vm2/vm2.img  70G
qemu-img create /vm/vm3/vm3.img  120G
qemu-img create /vm/vm4/vm4.img  120G
