I removed most of the other options. After rebuilding a new kernel, I restarted the machine. Before I started, I entered the following Sysctl command (and, of course, I put them in the/etc/sysctl.conf):
Sysctl net.link.ether.bridge_cfg=xl0:0,xl1:0
Sysctl net.link.ether.bridge_ipf=1

CentOS configuration of static IP addresses in VMware Bridge Mode
To solve this problem, we used the NAT mode When configuring a hadoop cluster under a virtual machine. However, there is another physical host in the LAN, we hope this physical host can communicate with the virtual machine. Then I decided to use the Bridged method and put them all in a network segment.
