asked 2013-09-12 12:27:22 -0500

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.

i use tcpdump to find why.

i find the packet is sent to the gateway, but no message send back.

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.
