今天早上開啟xshell連結虛擬機器，突然連結不上。然後進入虛擬機器執行 ifconfig 或者 ip addr list 命令發現eth0 不見。然後執行重啟網卡命令發現

解決辦法： 　　首先，開啟/etc/udev/rules.d/70-persistent-net.rules內容如下面例子所示：

　　#vi/etc/udev/rules.d/70-persistent-net.rules　　#Thisfilewasautomaticallygeneratedbythe/lib/udev/write_net_rules　　#program,runbythepersistent-net-generator.rulesrulesfile.　　#　　#Youcanmodifyit,aslongasyoukeepeachruleonasingle　　#line,andchangeonlythevalueoftheNAME=key.　　#PCIdevice0x1022:0x2000(pcnet32)　　SUBSYSTEM=="net",ACTION=="add",DRIVERS=="?*",ATTR{address}=="00:0c:29:8f:89:9　　7",ATTR{type}=="1",KERNEL=="eth*",NAME="eth0"　　#PCIdevice0x1022:0x2000(pcnet32)　　SUBSYSTEM=="net",ACTION=="add",DRIVERS=="?*",ATTR{address}=="00:0c:29:50:bd:1　　7",ATTR{type}=="1",KERNEL=="eth*",NAME="eth1"

　　記錄下，eth1網卡的mac地址00:0c:29:50:bd:17 　　接下來，開啟/etc/sysconfig/network-scripts/ifcfg-eth0 　　

#vi/etc/sysconfig/network-scripts/ifcfg-eth0　　將DEVICE="eth0"改成DEVICE="eth1",　　將HWADDR="00:0c:29:8f:89:97"改成上面的mac地址HWADDR="00:0c:29:50:bd:17"　　最後，重啟網路　　#servicenetworkrestart　　或者　　#/etc/init.d/networkrestart

　然後瞬間就滿血複活，xshell連結也正常了。
