VyOS Quick Start This article is intended to provide very basic configuration to get us started with VyOS. Our VyOS is installed in vSphere, specs below:   After VyOS is installed needs to be configured. It comes pretty blank so everything needs to be configured from scratch. This includes: User creation Remote access via ssh Basic firewall settings to allow remote access via ssh and respond to icmp echo requests  Interface configuration Before we begin we need to understand how VyOS works at a very fundamental level and learn few commands first. Vyos has two modes: Operational mode Configuration mode  Operational mode is the one where you usually display things and use show commands, similar to IOS. Operational mode is indicated by the $ at command prompt. Note, to descend back to operational mode from configuration mode use the exit command: Configuration mode is the one where you usually configure the router. All commands following th...

ESXi on KVM with Nested support. Installing ESXi on KVM is fairly easy task. Maybe because it belongs there? :) There are only few important things that have to be done right, rest is next next deploy. In this article we used ESXi 6.5 image. At the time of writing that is the latest and greatest ESXi version available. It comes with the WebClient naturally. In fact the WebClient has been officially around since 6.2 (optionally available since 5.5 & 6.0). Let me tell you however, it is still full of bugs. I am a Linux user, hence I couldn't test IE (all MS must die! :) but having a go with Epiphany, Firefox and Chromium  can confirm that Firefox works better than the rest most of the time. Chrome/Chromium often gets into "unexpected error - reload?" which most of the time cannot be even solved bu thrashing cache and history but requires more extreme measures such as deleting preferences or even reinstalling the browser. It is a lame provided the vmware corp...

Simple guide for creating a VM using oVIRT In this step by step guide we will create a VM using oVirt and highlight the differences between oVirt and vCenter as necessary to help admins migrate vSphere skills to oVirt with ease Here is discussed the whole process from transferring files to running a VM for the first time. On each step we elaborate below: STEP1: Downloading and uploading your ISO. First we make a decision on what VM we want to install. In this scenario we will grab Server 2012 as we already have license for one. Once the ISO is downloaded from Microsoft or elsewhere we need to upload the ISO to oVirt. This is plain file transfer between two machines, feel free to use SFTP, SCP, FTP as suitable. In our scenario SCP is used as the transfer is between to Linux client and SCP is built in CLI package to move files across.- - Check we have the ISO in our Documents directory - Upload the file to the ovirt server in then ISOs directory - Login to the...

.NET 3.5 on Windows Server 2012 with or without source ISO   When working on Windows Server where you do not have full control can be very tricky to install .NET 3.5 framework. This is especially the case when you are setting up a system for a customer on a cloud hosted server for example. You get your server from your cloud provider and you get credentials to login and thats all. No control over virtual environment.  Why would you need .NET 3.5 framework? - There are tons of applications that still use and are built on .NET 3.5 still and yes all those applications are current releases. Now, lets get down to business. You have two options to enable/install .NET 3.5 on server 2012 / 2012 R2 using few fairly simple steps. Both of this options are discussed below in its own separate section. Install .NET 3.5 framework on Server 2012 with INTERNET access In this scenario your server has Internet access. You do not have access to the source ISO o...

oVirt ISO Storage Domain In oVirt, since version 4 there is a new version type introduced " POSIX Compliant File System Storage". This means that now you can use standard linux file structure such ext4 to map storage to the cluster. This sounds like a vSphere now.  Remember how you can have combination of vSAN Datastore and Local Datastore available to ESXi? Does this means that we can now create partition on oVirt Node (KVM) an mount this as storage domain to the cluster? - Not so quick. oVirt is made for High Availability and builds on that concept. All hosts in the cluster MUST be able to see the storage domain. Even if you manage to add a local storage domain to oVirt, lets say ISO Storage Domain which makes perfect sense, you'll most likely end-up with orphaned cluster. All hosts unable to see the new storage domain will be kicked out of the Cluster. Now, since we've seen that POSIX Compliant File System Storage does not really make much sense ...
