Centos Virtual Machine for host access

The centos virtual machine requires two NICs (one nat and one bridging) to access the host machine. I used virtualbox to find ifcfg-ethX in/etc/sysconfig/network-scripts, X indicates the number of the network card, eth0, eth1 and so on, according to the number of the network card installed, this side appears in turn if there is no eth1, then cp ifcfg-eth0 ifcfg-eth1, and then modify the name and mac address, the mac address of eth1 is the address of the second network card of the VM. After modification, wq will save and quit service network restart and restart the network card. OK, I hope it will be useful to you.
