Add centos 6 Nic under Virtual Machine

Add a NIC for centos 6 under the virtual machine. You can add a NIC www.2cto.com for the VM "setting" option: I use VMnet2 (it doesn't matter if I select a single virtual machine !! But if you want two eth1 NICs of your two virtual machines to communicate, you must select the same mode !! That is, the two virtual eth1 NICs both choose VMnet2 or VMnet3. In short, they must be the same !!) 2. Check whether the NIC is identified! Vi/etc/udev/rules. d/70-persistent-net.rules # You can see two NICs! Copy the MC address of the eth1 Nic. Next we will create the ifcfg-eht1 file !! (At the beginning, I was depressed for a long time because I couldn't find this file !! Why don't you think about creating it yourself !!....) Three create ifcfg-eht1 Nic configuration file cd/etc/sysconfig/network-scripts/cp ifcfg-eht0 ifcfg-eht1 and then modify the NIC name/MC address/IP address and so on ..!! (Because we copied the eth0 Nic configuration) if we want the eth1 Nic of the two VMS to communicate with each other! You only need to set their eth1 NICs to the same Nic mode, and configure the ip addresses of the same network segment !!
