Asked by 贾宁

In a host, only one vm can access the internet.

if the host can access the internet, all vm can not access internet.

i don't know why.

hi 贾宁，

我可能误解了你的意思，你是说你有一台宿主机，其中只有一台虚拟机可以访问外网。
但是如果这台宿主机可以访问外网，其上得所有虚拟机都不能访问外网？是这样吗？

By the way, you can recheck these config items in nova.conf.
public_interface, flat_interface.

Hoping this help you.

regards,
gtt
