2.linux克隆虚拟机出现问题bringing up interface eth0:device eth0
[root@centos6 yum.repos.d]# service network restart

[ OK ]
Bringing up interface eth1: Device eth1 does not seem to be present, delaying initialization.
[FAILED]
#解决办法
此问题是因为我有两个网络配置文件冲突所造成
[root@centos6 yum.repos.d]# vim /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
TYPE=Ethernet
UUID=df653bc8-b366-48ea-996d-a3e3dda7f28c #删除UUID
ONBOOT=yes
BOOTPROTO=none
HWADDR=00:0C:29:E8:7D:BB #删除HWADDR
NAME="System eth0"
IPADDR=192.168.37.6
GATEWAY=192.168.37.2
DNS1=114.114.114.114
PREFIX=24
#删除网卡2配置文件
[root@centos6 yum.repos.d]# rm -rf /etc/sysconfig/network-scripts/ifcfg-eth1
#重启网络就可以了
[root@centos6 yum.repos.d]# service network restart
Shutting down interface eth0: [ OK ]
Shutting down loopback interface: [ OK ]
Bringing up loopback interface: [ OK ]
Bringing up interface eth0: Determining if ip address 192.168.37.6 is already in use for device eth0...
[ OK ]
或者执行【待测试】
[root@centos6 ~]# rm -rf /etc/udev/rules.d/70-persistent-net.rules
[root@centos6 ~]# reboot
[root@centos6 ~]# service network restart
3.YUM解决办法：
参考阿里云网站：
developer.aliyun.com/mirror/
#创建文件夹
[root@centos6 ~]# mkdir -p /etc/yum.repos.d/bak
#把/yum.repo.d/目录下文件移到yum.repos.d/bak下
[root@centos6 ~]# mv /etc/yum.repos.d/* /etc/yum.repos.d/bak
#替换为阿里云Vault镜像
wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-6.10.repo
#epel阿里云
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-archive-6.repo
#查看一下
[root@centos6 ~]# ls /etc/yum.repos.d/
bak CentOS-Base.repo epel.repo
