Clone centos and SET network connection

Whether it is hyper-V or VMWare,ClonedCentosLinux network cannot be connected

Ifconfig cannot see eth0. the following error occurs when you restart the NIC:
Bringing up interface eth0: Device eth0 does not seem to be present, delaying initialization. [failed]

Solution:

First, open/etc/udev/rules. d/70-persistent-net.rules, as shown in the following example:

VI/etc/udev/rules. d/70-persistent-net.rules

# Net device ()
Subsystem = "Net", Action = "add", drivers = "? * ", ATTR {address} =" 00: 15: 5D: EE: 4d: 03 ", ATTR {type} =" 1 ", kernel = "ETH *", name = "eth0"
# Net device ()
Subsystem = "Net", Action = "add", drivers = "? * ", ATTR {address} =" 00: 15: 5D: EE: 4d: 04 ", ATTR {type} =" 1 ", kernel = "ETH *", name = "eth1"

Record the MAC address of the eth1 NIC: 00: 15: 5D: EE: 4d: 04

Next, open the/etc/sysconfig/network-scripts/ifcfg-eth0

VI/etc/sysconfig/network-scripts/ifcfg-eth0

Change device = "eth0" to device = "eth1 ",
Change hwaddr = "00: 15: 5D: EE: 4d: 03" to the MAC address hwaddr = "00: 15: 5D: EE: 4d: 04"

Finally, restart the network.

Service Network restart
