Hello Nicolas,

Is it possible to use ovs-toolbox to connect 2 external VM(VMware) to OVS based on Ubuntu?

Proposed architecture:
Vm1-Web1(VMware)-(port 80)
Vm2-Web2(VMware)-(Port 80)
Vm3(OVS-Switch with Open Day Light Controller) with 1 interface(ens33) bridge to host(hypervisor)
A bridge is used to connect Vm1-Web1(VMware) and Vm2-Web2(VMware) deployed on Vm3 using tun tap virtual port.(ip tuntap add mode tap vport1)
Interface ens33 is connected to the bridge.
Interface ens33 should be able to communicate with hypervisor(Windows 11).
VM3 should be able to communicate to the Internet also.
Hence the hypervisor(windows 11) should be able to communicated to the bridge.(To connect to the 2 web servers).

I am have been able to manually setup the above configurations using reference video such as:
https://www.howtoforge.com/tutorial/software-defined-networking-sdn-openflow-and-ovsdb-connection/
https://www.youtube.com/watch?v=Gud2GoI-W_w
https://www.youtube.com/watch?v=rYW7kQRyUvA&t=4s

Can you please confirm we can can setup the above configurations using the ovs-toolbox?
Can you also please indicate any steps required to configured the above configuration?
I also did not identify any method to allow interface to get IP from dhcp.(Example on ubuntu using command dhclient ens33)

Thank you in advance Nicolas for your help,
Thank you,
Dheeraaj

Hello,

Do you think you might be able to help me figure out if I have done something incorrectly or if there is an actual issue?

I am trying to run ovs-toolbox on CentOS 7, and I think I followed the directions properly from the install directions at https://github.com/nbonnand/ovs-toolbox/blob/master/INSTALL

More specifically, it looks like I am running the following versions after installing it:

• CentOS Linux release 7.8.2003 (Core)
• python3.6 / python3.6m and python 2.7
• PyQt5 python3.6/site-packages (5.15.2) and python3.6/site-packages (from PyQt5) (12.8.1)
• paramiko python3.6/site-packages (from paramiko) (1.4.0) and python3.6/site-packages (from paramiko) (3.2.0) and (3.2.1)

When I attempt to run the Python Script ending in .py that is:

"./ovs-toolbox.py" at the Linux Command Line Prompt: # ./ovs-toolbox.py

I get the following errors/outputs:

]# ./ovs-toolbox.py
qt.qpa.xcb: could not connect to display
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, webgl, xcb.

Aborted (core dumped)
]#

Looking through Google, I am finding a decent amount of results, but I am not sure how relevant they are. What exactly is it asking to re-install, "Python, the ovs-toolbox, qt.qpa.xcb," or what? I attempted to re-install the python from sudo yum reinstall ..., and I re-downloaded and re-ran the shell to install the toolbox.

Do you have any ideas on how I might get this fixed?

I greatly appreciate any help that you can provide.

Thanks in advance,

Hello,

Do you have a transaction logs, which saves all the commend send to the OVS ?
Where we review all the commands and send for potential error?
The same transaction logs can be used as export or import for future projects.

Thank you,

Hello Nicolas,

The first step to use the tool-box is to create a profile.
If I have already a bridge configured with OVS running on Ubuntu.
How to connect the tool to an existing bridge which is already running?
Does it has the capacity to identify existing OVS configuration made:
Existing bridge created with tap interfaces?

Thank you,
Dheeraaj

how to change the ssh port?

Just thought I'd ask if there would be any possibility to add LXD container support for OVS-Toolbox?

There is a Python library for interacting with the LXD REST API: https://github.com/lxc/pylxd

What is LXD? LXD: Introduction

PyLXD API Documentation: http://pylxd.readthedocs.io/en/latest/

This is a test

Hello,Would you mind share the platform of fedora and ovs ans so on .you know if we get the wrong version of the environment ,we will face many problem.
