Hi, Bob, Thanks for your response. Finally I find the problem, it's the "Open Files Limit problem". I track the error log of ovs-vswitchd process and get this error log. After following the steps in https://rtcamp.com/tutorials/linux/increase-open-files-limit/, the problem is solved. @Ben, sorry for annoying you.
