  • Deploy vSphere VMs with Ansible!

    calendar Feb 4, 2023 · 3 min read · VMWare Home Lab vSphere FOSS/Linux Ansible Network Automation  ·
    Share on: twitter facebook linkedin copy

    In a previous post, we covered how to create a virtual machine from a VM template in vSphere using Python and the REST API as an example of service-agnostic methods to invoke infrastructure resources. VMware's PowerCLI is a fantastic tool, but it's not for me. Tweaking or porting functionality from PowerCLI to other …

  • Why Automate? VM Deployment with vSphere's REST API

    calendar Jan 5, 2023 · 7 min read · Linux VMWare Home Lab Python FOSS/Linux Jenkins Continuous Delivery JSON Programmability Jinja  ·
    Share on: twitter facebook linkedin copy

    VMware introduced RESTful APIs with their vSphere 7.0 release train; migrating from the old MOB APIs is a welcome choice. REST clients provide a powerful tool for automating processes, but it's important to embody reliable practices when interacting with infrastructure. The neat thing about published and documented …

  • What happens to packets with a VMware vSphere Distributed Switch?

    calendar Dec 26, 2022 · 4 min read · VMWare Home Lab Datacenter Networking Routing & Switching Studies  ·
    Share on: twitter facebook linkedin copy

    Distributed Virtual Port-Groups (dvPGs) in vSphere are a powerful tool for controlling network traffic behavior. vSphere Distributed Switches (vDS) are non-transitive Layer 2 proxies and provide us the ability to modify packets in-flight in a variety of complex ways. Note: Cisco UCS implements something similar with …

  • Security patches are available for VMware vCenter 8.0 - Let's try the new vCenter Lifecycle Manager!

    calendar Dec 17, 2022 · 2 min read · VMWare Home Lab Information Security vSphere  ·

    Let's take a look at the new lifecycle management process for vCenter. The old process via the VAMI was easy to execute - the industry is upping the ante with automated pre- and post-testing. Cisco's NX-OS installer is another example - complex procedures (in Cisco's case, sequential PGA or microcode updates) invite …

  • Using cloud-init with vSphere and openSUSE 15.4

    calendar Sep 23, 2022 · 7 min read · Linux VMWare Home Lab vSphere FOSS/Linux Cloud  ·
    Share on: twitter facebook linkedin copy

    Rapidly deploying Linux servers to meet a whim represents the essence of home lab activities, but we spend a great deal of time spinning/configuring machines to meet our specs. Worse, we lose a great deal of time keeping them properly configured and up to date, and none have the privilege of unlimited lab time. Let's …

  • NSX Data Center 4.0.0.1 is now available!

    Share on: twitter facebook linkedin copy

    NSX 4 is now available, and it was a surprisingly sparse release in terms of new capabilities. NSX 4.0 appears to be a "clean house" initiative, so while it's missing "whizz-bang" new data plane features it does address a variety of issues I am happy to say are now closed: Numerous documented API …

    Share on: twitter facebook linkedin copy

    VMware's vDS is a bit of a misnomer In a previous post, I covered the concept of transitivity in networking - but in Layer 2 (Ethernet) land, transitivity is critically important to understanding how VMware's Virtual Distributed Switch (vDS) works. The statement "VMware's Virtual Distributed Switch is not a …

    Cisco Modeling Labs (CML) has turned out to be a great tool for deploying virtual network resources, but the "only Cisco VNFs" limitation is a bit much. Let's use this opportunity to really take advantage of the capabilities that NSX-T has for virtual network labs! Overview For the purpose of lab …

    Spanning Tree is the all-important loop prevention method for Layer 2 topologies and source of ire to network engineers worldwide. Usually IT engineers list the Dunning-Kruger Effect in a negative context, depicting an oblivious junior or an unaware manager, but I like to focus on the opposite end of the curve with …
