RHEL克隆虚拟机后改变网卡地址

（一）更改hostname

# vi /etc/sysconfig/network

NETWORKING=yes
HOSTNAME=your-vm-hostname-here

（二）更改网卡地址

在使用virt-manager或virtual-box克隆了RHEL6的虚拟机之后，网卡地址需要手动更改。

首先在virt-manager中查看虚拟机属性： View->Details

Overview  |  Basic Details

                          Name: vm-rhel64-aa

                          UUID: 6529d110-4191-e724-9c4d-aaa5db31fefd

NIC:22:d6:4b |  Virtual Network Interface

                             Source device: Virtual network ;default‘:NAT

                             Device model: virtio

                             MAC address: 52:54:00:22:d6:4b

记下上面的UUID和MAC.

1) 进入虚拟机，编辑文件：

# vi /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0
HWADDR=52:54:00:22:D6:4B
TYPE=Ethernet
UUID=6529d110-4191-e724-9c4d-aaa5db31fefd
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=dhcp

2) 删除文件：70-persistent-net.rules

# rm /etc/udev/rules.d/70-persistent-net.rules

3）重启系统

# reboot

现在虚拟机应该获得了新的hostname和MAC地址。
