The neutron DHCP agent does not issue leases for ports that don't exist in
the Neutron DB. There was a time when it would issue a DHCPNAK to other
DHCP traffic[1], but that's been fixed for quite some time now. perhaps
that was the bad behavior in Juno that you observed?

I am not sure if there is any specific d
this is how i do things without dhcp services in the network.
1. enable config-drive within server declaration
2. using cloud-config write out the network l3 information to a file on the
guest.
3. using cloud-config you can then add an user-data script to your
config-drive,
4. the user data script
Robert,
I didn't find any related configuration which blacklist mac address on
Mitaka. also i didn't find any document stated that DHCP agent only
gives ip address to instance mac address.
Do you point me to any doc or any kind of material

Are you sure it was DHCP misbehaving?
Because it could also have been that it tried to takeover the gateway IP.
That would certainly mess with connectivity on the network.
Just mentioning because you gave the example --router:external while I think it
should be --router:external True
Also if it
Robert,
I remembered in JUNO release when i did flat network with my existing
provider LAN then DHCP started giving IPs to my existing LAN clients
and people started yelling their network is down :(
Following networking i configured.

I do not think this should happen.

I am using neutron networking with vlan ( its provider VLAN). We are
not using DHCP but i need some kind of hack to inject IP address in
instance using cloud-init.
We are using cloud-init but i don't know how does it work and get IP
from neutron. I am new with neutron stuff.

solution. We are no using DHCP with openstack (there is an reason) so
not if i boot my VM it didn't getting IP address on eth0 interface so
i have to manually configure IP address.
Is there any script or API which i can put in VM gues
