Hi, Sergey,
I remember I had similar problem when I switched to quantum(neutron's
previous name) from nova-network.
But, I can't recall how I solved it exactly, it would be something like
previous nova-network NAT caused the problem, so, if you switched to
neutron from nova-network at the same system, you might want to look at
your NAT to see if you still have some NAT setup remaining that came
from nova-network, and (e.g. redirect :80 to 0.0.0.0:8775)
> I guess, metadata service is supposed to listen on 192.168.0.2,
but it's not.
Yes, it's not, if I understand it correctly, it will be redirected to
metadata port in name space, so, you won't see it actually listens on 80
port.
Best regards,

Hi, Mike.
There are no routes in my VM's except for the default one. Private
subnet I'm using is 192.168.0.0/24 <http://192.168.0.0/24> with
neutron router on 192.168.0.1.

Following is a part of Fedora cloud-init script output. Instance
tries to get info from 169.254.169.254 and then switches to
192.168.0.2, which is an interface with dnsmasq injected by neutron.
I guess, metadata service is supposed to listen on 192.168.0.2, but
it's not.

Did yo look to see if there is a wrong route in your VM?
�Sometimes I find the metadata service is messed up by a bogus
entry in the VM's routing table.
