1、1Device does not seem to be present1.1現(xiàn)象1.2原因及場景在 VMware 中安裝的 linux 虛擬機(jī)出現(xiàn)了這個問題，問題的產(chǎn)生是因為之間做過部分的修改，clone 等操作。1.3解決方案1.修改 Centos 虛擬機(jī)克隆機(jī)的 HWADDR 為ifconfig-a的MAC地址形如：HWADDR=00:0C:29:90:A7:23然后再做以下操作:；2.2Connection activation failed2.1現(xiàn)象2.2原因及場景在 Redhat6 虛擬機(jī)下啟動（start）eth0 報錯 Error: failed: Device not mana
