I am trying to set up a virtualized environment for SDN, I am trying to connect 2 hosts which are 2 machines in Windows 10 and than connect it with an SDN controller, I am trying to connect them with an Open vSwitch but unfortunately the controller connection is still not set up. I would like to ask for some help on how to set it up and more ideas on how I can do this set up any help would be very appreciated.GNS3 SETUP

I install latest Ryu controller from pip install(Python3) in Ubuntu 14.04 on VM(VM-A), and NIC configure as bridge mode(192.168.88.252).
I assume VM-A's host is "Host-A"
And connect physical Zodiac FX Openflow switch, port4(reserve for connect with controller, 192.168.88.252) to router(192.168.88.0/24)
Zodiac FX port3 connect to router(192.168.88.0/24)
And connect Two RPI(AKA Host-B,C) on Zodiac FX port 1,2(so, two rpi will get 192.168.88.250, 192.168.88.249)
And connect controller Host-A to router(192.168.88.253)
It work fine, and two rpi able to connect internet.
Host-A able to connect two rpi.
But if I trying to use VM-A to do any kind of connect with two rpi.
Hole controller will stuck for few minute, an get message:
DPSET: Multiple connections {dpid}
I wounder to know there is illegal when I using SDN controller to communicate with openflow networking devices?
In my case, my ryu app run simple_switch_13.py.
Thanks!
If I spread another subnet(192.168.80.0/24) for sdn switch communicate with controller.
This problem solved!, SDN controller need another NIC to connect another subnet.
I still can using SDN controller access 192.168.88.0/24 without DPSET problem.
as stated in my question. I'm trying to have connection to a virtual machine remotely without enabling virtualbox remote desktop screen. using the network host only. but I could not make this connection without having to enable the option on the screen.
according to my research it is possible because applications as Andy or genymotion does this.
if anyone knows the subject. appreciate your help
Networking is not a strong skill set of mine and I'm new to VirtualBox..so here we go -
I've got a Windows (XP) VM running on VirtualBox. I am able to use remote desktop to connect to the VM with no problems.
The Problem: I need to connect to another network via VPN on the virtual machine. However, once connected, all local network resources become unavailable. As a result, my remote desktop session is disconnected.
Question: Is there another way to remotely access the VM? Is there some way that VirtualBox can route me to the VM without using the Windows RDC functionality so that I can have an active VPN connection but still control the VM remotely.
Should have done some more research. This feature is already built into VirtualBox. You can log into the VM through the host machine.
All you have to do is turn on remote display in the settings for the VM and choose the port that you want to use (make sure to make appropriate firewall changes). Then you remote to that port on the host machine.
Ex: Host machine has an IP of 192.168.1.200 and you set up port 3395 for the remote display - you would open Remote Desktop Connection and use 192.168.1.200:3395 and it would open the VM.
More detail from the VirtualBox site.

I'm trying to develop an interface to an application that doesn't run on Windows 8. Hence, I've created a VM with Windows 7 running the integration service and another service running on the Windows 8 host.
I have three Virtual Network scenarios configured for Hyper-V: Wireless, Shared and Internal. Where Wireless allows all VMs and the host to connect to a wireless network (External), Shared let's the VMs connect through the host via a VPN (Internal) and Internal creates a network within the host where the VMs don't have network access (Private).
When I'm in Wireless (External) mode and there's a wireless network to connect to, everything works fine as if I were testing using to physical PCs on a wireless network. However, today I had a situation where I wasn't connected to a network but still wanted to do some testing and I could not get the VM to see the host and vice-versa. This scenario was quite straight forward to create on VMware which I used before switching to Hyper-V...
Has anyone managed to make Client Hyper-V VMs and the host communicate without a network? Can you guide me how to set it up?
Wireless networking under Windows 8 Hyper V can not communicate with multiple VM the Wireless NIC is assign to only one Hyper V internet connection,
Meaning only one Hyper V can connect to the Internet preventing others from connecting unless you use multiple Nic's Wireless Network Cards or USB Wireless Network.
It is only after you restart or shut down your computer that Hyper-V problems start.
So if you can not connect any of your Hyper VMs then you problem could be due to a shutdown error that Hyper-v in counted Try restarting the whole computer then Hyper- VMs your problem should fix itself.
Might want to try this. I am having similar problems as you and all signs point to this particular solution working, but for me it is not. Might help you, though.

The solution that DID end up working for me was this:

My situation:
I am running (evaluating) Windows 8 (RTM) on my Laptop.
I am connected to a LAN which has NO access to the internet (DEV-LAN).
I am running a virtual machine (VMware Workstation) which is connected via Bridge Mode to the DEV-LAN. This virtual machine has no access to the internet.
Before, with Windows 7 I was able to connect the host via UMTS to the internet while the virtual machine still was connected to the DEV-LAN. So I could keep working within the virtual machine while doing research (MSDN, Google, Stackoverflow) in the internet on the host.
When I now connect the Windows 8 host to the mobile broadband, nothing changes in the runtime behaviour. The whole Network communication is still running over DEV-LAN. Windows 8 tells me in the Network Sidebar that mobile broadband is connected, but it does not use it. When I remove the network plug of DEV-LAN, THEN the broadband connection will be used. But then obviously, I cannot work in my virtual machine, which depends on DEV-LAN.
Question:
Is there any switch in windows 8 that I can use to tell the system to use broadband over LAN, when available?
Thanks a lot!

edit for the comment of pst: the following metrics are given
IPv4-Routentabelle
===========================================================================
Aktive Routen:
Netzwerkziel Netzwerkmaske Gateway Schnittstelle Metrik
0.0.0.0 0.0.0.0 192.168.23.1 192.168.23.12 25
0.0.0.0 0.0.0.0 77.24.97.50 77.24.97.49 296
It finally works :-)
I set the metric of my LAN-Adapter to 999 and everything is as I want it to be.
Any change of the UMTS Adapter to a lower metric was unsuccessful.
Even when I set the metric to 1 or 5 or 10, netstat /rn told me a metric > 50.
So when I cannot lower the one metric, I have to raise the other one ;-)
The metric can be easily changed like follows:
System Settings
Network and Internet
Network Connections
Ethernet -> Context Menu -> Properties
Select Internet Protocol (v4) -> Properties
Advanced
Automatic Metric off and manually set to 999
