2015-10-22 07:00:08 -0600 asked a question HEAT OS::Nova::Flavor doesn't exist in Kilo


According to the HEAT resources (documentation), in the Kilo version HEAT supports the OS::Nova::Flavor resource.

But in my OpenStack (Kilo version) I don't see that resource at the "Resource Types" listing and when I try to create a stack with a template using that resource, Heat shows "ERROR: Unknown resource Type : OS::Nova::Flavor".

Is the documentation correct? Do I need to do something to enable this resource?

2015-05-13 13:44:22 -0600 asked a question Update floating ip pool range

I need to add more floating IPs to the external network pool, but I don't want to mess with the already allocated floating IPs.

It's possible to add more floating IPs to the external network pool without deleting it or deallocate the already allocated floating IPs?

2014-11-06 09:52:22 -0600 asked a question Is there a OpenVPN driver for VPNaaS?

The title says it all.

I'm using the Openswan driver. Is there an OpenVPN driver?

Where can I see list of available drivers for VPNaaS?

I guess that this problem is regarding communication with VLAN and your guide doesn't cover that.

2014-10-13 07:20:09 -0600 commented question Set up devstack with two ethernet interfaces

I installed Wireshark and checked that when I ping from the physical machine to the router/ VM inside devstack there is an ARP communication (request and reply) and my physical machine stores the MAC address inside the arp table. But the ICMP PING or other kind of communication, doesn't get through

2014-10-03 11:00:15 -0600 asked a question Set up devstack with two ethernet interfaces

I'm trying to setup a devstack VM using virt-manager. The VM must have two interfaces: 1 interface to internet (eth0) and 1 interface to connect to another physical machine (eth1). I setup this at my local.conf:




# Passwords and token

# Fixed and floating subnets

# Reclone each time

# Disable Nova Networking
disable_service n-net

# Neutron - Networking Service
enable_service q-svc
enable_service q-agt
enable_service q-dhcp
enable_service q-l3
enable_service q-meta
enable_service q-metering
enable_service neutron

# Neutron - VPN as a Service
enable_service q-vpn


The devstack buildss successfuly. The instances created in openstack have internet communication. I then create a provider network that maps with physnet1:

neutron net-create provider --shared --provider:network_type vlan --provider:physical_network physnet1 --provider:segmentation_id 3500

And create a subnet:

neutron subnet-create --name provider_subnet provider

I launch a VM and a router in this new network and they ping each other. Then I add eth1 to br-eth1 with:

ovs-vsctl add-br br-eth1 eth1

So that network maps in the eth1 interface. Then I connect a physical machine to eth1 with a network cable and set the the vlan ID 3500 for the interface. When I try to ping from the physical machine to the router or the VM inside devstack I don't get communication.

Is there any missing configuration in devstack local.conf?

Thank you

2014-02-26 10:44:05 -0600 commented question Problem with bridging two networks with a VM

So, do I need to disable security groups in horizon? I've found this Or do I need to clear the iptables relating to that VM interfaces. My VM don't have ip address, so only do layer 2 communication. Do I need to use iptables or ebtables?

2014-02-25 07:19:21 -0600 commented question Problem with bridging two networks with a VM

Thank you for your help. I did turned off hairpin and the "ARP craziness" stopped. My VM in the green network receives the ARP Reply from the router. It populates it's arp table. But for the ICMP packets (ping), I can they are going out but the VM connecting the two networks don't see that packets.

2014-02-24 07:09:41 -0600 commented question Problem with bridging two networks with a VM

I am doing virtualization of network functions (NFV). In this scenario I'm trying to implement a WOC (WAN Optimization Controllers). A WOC needs a layer 2 VM that can connect two network segments.

2014-02-21 10:04:59 -0600 asked a question Problem with bridging two networks with a VM


I'm struggling with this problem the last two weeks.

I'm using Openstack Havana and I want to implement this network topology. (image description)

The network configuration is the follow:

  • All the VM's are using Ubuntu Server 12.04;
  • The orange network have a DHCP server and the gateway is the router connected to this network;
  • The green network don't have DHCP Server as I configure a static IP in the VM connected to this network.
  • The VM with a blue circle have eth0 connected to orange network and eth1 connected to green network.

I want the VM from the green network to be able to talk to other VM's from orange network and to the router. All the comunications will go through the VM (blue circle) that are connecting the two networks, like a layer 2 bridge.

Info: Don't tell me that I can use a router to connect the two networks, as I need it to be connected using a VM.

All the VM's from orange network are talking with each other and with the Internet. All is good.

So, I need to configure the bridge VM (blue circle VM) to act like a layer 2 bridge. This is done inside the VM:

sudo ifconfig eth0 down
sudo ifconfig eth1 down
sudo brctl addbr br0
sudo brctl addif br0 eth0
sudo brctl addif br0 eth1
sudo ifconfig eth0 promisc up
sudo ifconfig eth1 promisc up
sudo ifconfig br0 promisc up

Ok, now I have the two interfaces bridged and theoretically all the packets can be passed from one network to the other network, because of the promisc mode....theoretically.

Next I go inside the VM connected in the green network and do this:

sudo ifconfig netmask
sudo route add default gw

I give it an IP and I add a default gateway, that is the router in the orange network.

Now it's time to test the connection. I place tshark in one of the tap network in the bridge VM

sudo tshark -n -i tap383f8a7c-86

And I do a ping from the VM that are connected to the green network

ping (This is the IP of the router)

This is when the strange things happen. The network traffic at the bridge goes crazy. So as you can see I created a pastebin output. (ARP craziness)

With the tshark information, I can see that the bridge catches the ARP Request (broadcast) and the ARP Reply (unicast)

But the VM in the green network outputs me this:

PING ( 56(84) bytes of data.
From icmp_seq=1 Destination Host Unreachable
From icmp_seq=2 Destination Host Unreachable
From ...
