Virtual Network card usage notes

If the NIC error when restarting, said to find no device.

We need to check the following 3 places.

One, the virtual machine link mode:

1. Bridge connection

2. Nat

Second, ifconfig corresponding to the ETH relationship, such as eth1, and 0, and 2 and the like, usually error is not corresponding

Third, /etc/udev/rules.d/70-persistent-net.rules

There is a problem gave words, side see ifconfig out of the network card name, and the name of the above path is the same, if not good, then modify the same.

Modify and then go to/etc/sysconfig/network-scripts to modify the corresponding NIC name

One thing to remember, this type of error should be added to the new virtual machine network card caused, so to go to the ifconfig to the MAC address copied to /etc/sysconfig/network-scripts replace the corresponding network card.
