I think the dhcp message is intercepted by your host's dhcp server.

Subject: [Openstack] Networking Issue (of newly launched instance)







Hi All,

I have been able to launch an instance using devstack's dashboard. Now there seems to be networking problem. The log of the launched instance shows the following message repeatedly:

cloud-setup: failed 1/30 : up 1.23. request failed
wget: can't connect to remote host (169.254.169.254): No route to host

and afterwards, the log shows:

Although the dashboard shows an IP of 10.0.0.3 for this instance, yet within the logs ifconfig -a is showing 10.0.3.19. I am not sure how this instance is connected to my host (or how it should be connected to my host). Someone help please, I can not even login to the instance using VNC. (Any insights to the networking part would be really helpful)

This is my setup:
My host VM (which is hosting devstack) has two VNICs: eth0 is NAT (IP:10.0.3.15) and eth1 is host only (IP:192.168.124.2). All devstack's configuration has been done with respect to 10.0.3.15 (i.e all services are bound to this address)
