Public bug reported:

 
I found that the cloud host I created cannot connect to the network. The network type is VXLAN, and it cannot even access cloud init
I used this installation document (partially in Chinese) and it was normal around 2022, but it cannot be used after updating the software source recently.

The use of VXLAN in cloud hosts has the following faults
(1) Unable to access network resources other than ICMP (ping), and even curl http://169.254.169.254 (This also leads to the inability to use cloud init)
(2) Sometimes unable to ping 169.254.169.254 for unknown reasons.

All firewalls and security groups are allowed or closed.

My network situation is as follows
Internal (vxlan) 10.0.0.0/24 Gateway 10.0.0.1
Router gateway 10.0.0.1 → 192.168.10.121
External (flat) 192.168.10.11.0/24 Gateway 192.168.10.1.1

If any other information is needed, I can provide it and hope to fix
this error.

system version:ubuntu 22.04 last  version (online )
openstack Y version
