This morning open Xshell link virtual machine, suddenly link not on. Then go into the virtual machine execution ifconfig or the IP Addr List command to find eth0 missing. Then perform the restart NIC command found 650) this.width=650; "src=" Http://i.imgur.com/8ZI8Ki8.png "style=" margin:0px;padding:0px;border:0px; " alt= "8zi8ki8.png"/>

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

　　# vi /etc/udev/rules.d/70-persistent-net.rules # this file was automatically  generated by the /lib/udev/write_net_rules # program, run by the 　　Persistent-net-generator.rules rules file. # # you can modify it, as long as you keep each rule  on a single # line, and change only the value of the　　 name= key. # pci device 0x1022:0x2000  (pcnet32) subsystem== "NET",  action== "Add",  drivers== "? * ",  attr{address}==" 00:0c:29:8f:89:9 7 ",  attr{type}==" 1 ",  kernel==" eth* ",  name=" eth0 "#  PCI device 0x1022:0x2000  (pcnet32) subsystem== "NET",  action== "Add",  drivers== "? * ",  attr{address}==" 00:0c:29:50:bd:1 7 ",  attr{type}==" 1 ",  kernel==" eth* ",  name=" eth1 "

Record the MAC address of the eth1 Nic 00:0c:29:50:bd:17 Next, open the/etc/sysconfig/network-scripts/ifcfg-eth0

# Vi/etc/sysconfig/network-scripts/ifcfg-eth0 Change device= "eth0" to Device= "eth1" and Change hwaddr= "00:0c:29:8f:89:97" to mac ground above Address hwaddr= "00:0c:29:50:bd:17" Finally, restart the network # Service network restart or #/etc/init.d/network restart

Then instantly the blood is resurrected, and the Xshell link is normal.
