Well after the series regarding integration with a Cisco 9k, I thought that we also needed something regarding Open-Source.
Well VyOS does not get any more open source than that, we will integrate a PVE cluster with a VyOS as a leaf. In addition we will use VyOS as an eBGP peer to access external clients. Read on! Continue reading “PVE SDN VyOS Integration Oh My!”
In the final part of these series, we will integrate a Cisco 9k with a PVE cluster using the previous configurations we did setup.
In part 2 we will continue with integration of a PVE cluster with a Cisco 9kv running NXOS.
Figure 1. shows the network diagram.
We are using the 9000v as an eBGP peer for the PVE cluster. Any device that supports BGP can replace the Cisco 9k. Continue reading “PVE VXLAN NXOS Integration Continued Oh My!”
The purpose of the following proof of concept is to demonstrate integration between Proxmox PVE and a Cisco 9000v.
PVE is a fantastic open-source virtualization environment. Recently it has gained a lot of traction in particular with the issues with VSphere licensing.
However, while I see several blogs and videos regarding it and in particular its SDN capabilities, I have not seen detail setups involving integration with other SDN devices.
This is unfortunate since the Cisco 9000 for example is very prevalent and at one point if someone decides to move to PVE, they will need to integrate Cisco or another device to it.
In any case, from the perspective of learning I think the following will be very instructional. Continue reading “PVE VXLAN NXOS Integration Oh My!”
Hello there,
It has been a while since I posted.
I decided to do DDNS on my home network using Bind9 and the ISC DHCP server.
As always you test on a lab first.
I have EVE-NG and I was running a lab with DDNS and IPV6.
I used Fedora core so to make it like my network I replaced the server with Ubuntu 20.04.
However, I run into an interesting problem.
A few weeks ago, my Internet router died suddenly.
Not that much of an issue unless you use a custom box as a modem and you have your website hosted on it.
The server I was using for this was a Fedora Core 9 machine. I know an ancient OS.
The machine itself was not that old, I found about 4 years a cheap Intel 386 with ISA support so I replaced the really old server I had. I was able to migrate to the new box, I was running a hardware raid setup using an ISA card. Talk about making things complicated.
I initially tried using a virtual server to have things running quickly, I had a backup of the server running on a VMware workstation however, I could not make it a go for reasons that may merit another blog.
However, I had laying around my old media server, 4 Gb of ram and 500 GB of disk space. Too much space but that was the only thing I had. It only had one NIC but I found a USB to Ethernet dongle.
This time I decided to use HAproxy to present my website and blog and have proper SSL certs for each.
You can use a Linux server as a managed bridge if you would want to.
The discerning reader would point out that this is already possible however, without spoiling the ending I will come back to this point at the end.
Keep on reading…

Hello there,
I have used VXLANs with EVPN using Cisco ACI and the APIC controller. While the APIC controller is great, it masks a lot of the configurations done on the spines and leaf devices.
I currently do not use VXLANS at all so I decided to circle back and reacquaint with it. However, since I decided to do this in my home office lab environment I said to myself let’s use CLI commands.
Got the lab working and it was great to a point, run into an issue that drove me crazy for quite a bit.
Hello there,
Recently I encountered an issue, which is rampant, and people complaint a lot about it.
All of a sudden, Chrome would not load. I was getting “Page unresponsive”.
This is happened to me once before, on my work computer Chrome become sluggish as molasses. Try a few of the things you find on the Internet, did not work.
Then as sudden as it started it went away. No explanation.
A few days ago, on my home computer Chrome started to behave that way. Nothing worked.
I started using Firefox again which was fine, this was a clue that the culprit was Chrome.
I know what you are going to say, there was a virus, blah, blah, blah.
Nope, there was no virus. Will not go onto how I was certain, I have AV plus other things and after checking there was no virus.
Finally, I decided to uninstall and reinstall Chrome. No luck.
What was one to do? Then it dawned on me. Why don’t I try the 32-bit version? Yes, you can still get it and it is not as much of a memory hog as the 64-bit version.
So, I did uninstall the 64-bit version and install the 32-bit version.
What do you know it resolved the issue, for a while it seemed that the issue was still there however after a couple of minutes Chrome started to behave normally.
Once again, I have no explanation.
Weird.
Take care.
Ciao.
Hello again,
I have used virtualization for a while now in the enterprise.
Mostly using Esxi and vSphere, using servers with 256 GB of memory and Terabytes of backend space (iSCSI, Fiber, NFS, etc.). Also, some KVM setups when Open Source was the only viable option due to pricing, etc.
At home, I have used either the free version of VM-workstation or VirtualBox.
I have not needed something more powerful. Just enough to test a new Linux distro for example, or run a KVM image.
However, I started to use GNS3 to run big labs at work. Then I switched to EVE-NG. This was not an issue of course since I had the virtual resources.
At home, it was a different story could not run big labs just the simplest ones.
Thus, I started to look to get some computer power. I could have got a server of e-bay for some decent price. However, they are noisy as hell.
