In that case you have two options:<br><br>1) use floating ips <br>2) create a provider network that bridges to the same physical of the hosts that you want to be able to contact your vms. <br><br>Aaron<br><br><div class="gmail_quote">

<div>Could you please tell me your "physical

Anyway, what you need is not requiring having a floating IP pool
inside the same network, you can also play with static routing :
if your physical host does have a default gw, you can create a
static route from this gw to the VM network gateway. And on the VM
network gateway, do the same...<br>

<div>Hey Sylvain,</div>
</div>
<div><br>
</div>
<div>Basically what I need is to have the VMs mapped
to my physical network so that my physical hosts can
directly access the VMs. How can I do this?</div>

<div>Hi,<br>
<br>
I don't understand your business. Should you have a <a href="http://192.168.1.0/24" target="_blank">192.168.1.0/24</a> network for
management, you could also assign an external network
with Quantum based on the same subnet (ie. <a href="http://192.168.1.0/24" target="_blank">192.168.1.0/24</a>). <br>
When creating a floating IP pool, Quantum does require
at least 3 things : <br>
- the CIDR<br>
- the beginning and ending IPs <br>
- the external gateway <br>
<br>
So, based on what I previously said, you only need to
create a <a href="http://192.168.1.0/24" target="_blank">192.168.1.0/24</a>
in Quantum with .1-.100 (for example) as the range,
.254 being the external gateway.<br>
<br>
Thanks,<br>

<div dir="ltr">After reading a little bit
more, I think I have found what I need.
It is a provider network that I need
for the VMs so that they can get access
to the other resources in my main
network ( such as other physical hosts
that are connected to the same network
).
<div> <br>

<div>My question is, is it possible to
do this alongside the use case that I
have followed ( Provider router with
private networks)?</div>

<div>Hello,</div>

<div>I want to know how I
can allocate a dynamic
IP to the VM from the
same network as the
openstack hosts
(controller/network-node/compute
node) network/management
network . For example,
in virtual box you can
give your VM an IP from
the host's network using
a Bridge adapter. How
can I do this in
openstack?</div>
<div><br>
</div>
<div>From what I
understand floating IP's
are used when you have a
public IP </div>
<div> (which is static) to
be allocated to VM's.</div>
