Re: neutron's OVS based VXLAN seems to be unable to access the network

I found a very strange situation where all services except ICMP are not inaccessible and often times out. Basically, run curl http://169.254.169.254 It will take about one minute. Unable to access external networks (such as linux.com), DNS parsing is difficult, and ping commands can sometimes work. According to the latest documentation, the configuration has been adjusted and the Neutron database has been removed to truly update it
