Redhat virtual machine configuration bridging method Device eth0 does not seem to be present, dela

The Redhat Virtual Machine configures the bridging mode Device eth0 does not seem to be present. delaying initialization imports an existing RHEL6.x Virtual Machine in Virt-manager. After the VM is started, it is found that the NIC is not started. Restart the network service and find the error message "Device eth0 does not seem to be present, delaying initialization. "solution: 1. delete/etc/udev/rules. d/70-persistent-net.rules and restart the machine. The file 70-persistent-net.rules determines the binding between the nic and the MAC address. After the existing virtual machine is imported, the MAC address of the NIC changes, so the system determines that the network device does not exist. 2. After such processing, eth0 cannot be started normally. You need to set/etc/udev/rules. d/70-persistent-net.rules the last modification in the file "eth1" to "eth0", then change the MAC address in/etc/sysconfig/network-scripts/ifcfg-eth0 to/etc/udev/rules. the address recorded in the d/70-persistent-net.rules file, and then restart the machine. eth0 can be started normally.
