The interface name of a network device increases if the mac address of the physical or virtual network card changes. A common case is if you made a clone of a virtual machine for example via VMware or KVM or replaced a physical network card in a non virtualized server.<\/p>\n

\n

If it\u2019s a CentOS 6 machine you need to change 2 files to rename the interface for example from eth1 back to eth0.<\/p>\n

One file is the udev rule for network devices which is located here:<\/p>\n

\/etc\/udev\/rules.d\/70-persistent-net.rules<\/p><\/blockquote>\n

Copy the new mac address to the line of your eth0 rule and delete the new rule for eth1.<\/p>\n

# PCI device 0x15ad:0x07b0 (vmxnet3)
\nSUBSYSTEM==\u201dnet\u201d, ACTION==\u201dadd\u201d, DRIVERS==\u201d?*\u201d, ATTR{address}==\u201d00:50:56:b2:23:e0\u2033, ATTR{type}==\u201d1\u2033, KERNEL==\u201deth*\u201d, NAME=\u201deth0\u2033<\/p><\/blockquote>\n

Modify the network configuration located under:<\/p>\n

\/etc\/sysconfig\/network-scripts\/ifcfg-eth0<\/p><\/blockquote>\n

and replace the old ip with the new one and the old mac address with the new mac address.<\/p>\n

To be sure everything works fine reboot your machine.<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
