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 with neutron router on 192.168.0.1.

# route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use
Iface
0.0.0.0         192.168.0.1     0.0.0.0         UG    0      0        0 eth0
192.168.0.0     0.0.0.0         255.255.255.0   U     0      0        0 eth0

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.
