First, due to the NIC problem, we can't configure the IP and gateway information for the host during the procedure to install the OS of the host. Then, we have to configure the IP and gateway information mannually.
But at the beginning, we have the wrong configuration for the gateway by recording it in the file/etc/sysconfig/network-scripts/ifcfg-eth0, so even if the real communication is alright between the HOST and the local PC, the installation progress is still failed.
At last, we confirm that we have to configure the IP and gateway by the command "hostconfig" on the HOST, and then the gateway will be recorded in the file /etc/sysconfig/network/routes, with this way, problem can be resolved.
