Mission Critical Virtual Machines on VMware vSphere

Building Mission Critical VMs on VMware vSphere is pretty simple. There are just a few commonly acknowledged Best Practices with which to adhere, regardless of whether you are installing Windows or Linux:

  • Use Paravirtualized drivers wherever possible
  • Remove unnecessary hardware from the VM (settings)
  • Disable unnecessary or unused devices in BIOS
  • Assign no more resources to the VM than are actually required

In the following steps, I am going to be building a VM to serve as Active Directory Domain Controller for my lab (jb-lab.local) on Windows Server 2012. Continue reading “Mission Critical Virtual Machines on VMware vSphere”

Building Ubuntu Server as a VM on ESXi

Ubuntu is one of the most well-known and useful server Operating Systems available. Today I am going to show you how to build Ubuntu Server 14.04.3 LTS as a Virtual Machine running on VMware vSphere ESXi using the VIrtual Machine Remote Console (VMRC) and ISO Image on local disk. Let’s get started…. Continue reading “Building Ubuntu Server as a VM on ESXi”

Installing open-vm-tools on Ubuntu Server

Most every Virtual Machine needs to have some sort of VMware Tools running. In the “Old Days,” the norm was to mount an ISO provided by VMware and install their version of the VMware Tools. More recently, VMware has been encouraging Operating System vendors and communities to develop their own version of the VMware tools, which are known as the “open-vm-tools.” The VMware Tools (VMware ISO) installations for most Operating Systems are now described as “deprecated”.

In the following steps, we will install open-vm-tools for Ubuntu from the command line. In order to do this, our VM needs to have access to the internet to be able to download the packages from the configured repositories.

Preparing for Disaster

I was in Manhattan during Hurricane Sandy. The path of the storm was clear, and the outcome largely pre-determined. Because the company I work for (VMsources) has many clients in Manhattan, it was decided that the best place for me, were disaster to strike, was right in Manhattan.

Qualifying vSphere releases for use in production

If you have ever wondered when it time to upgrade VMware vSphere; you might want to consider the experience of the unfortunate and unwise early adopters of vSphere 5.1. The time to upgrade is clearly NOT the first public release of any new version of vSphere! Continue reading “Qualifying vSphere releases for use in production”

Diagnosing and fixing Virtual Machine Remote Console MKS problems

vCenter_client_connectionsVirtual Machine Remote Console (VMRC) issues, also known as MKS Errors, seem to be more and more common these days. The causes and solutions to most of these problems are the same for the large-scale user of vSphere Enterprise Plus as they are for the home-lab user on a trial license. It usually boils down to one fulcrum: The client (vSphere Client for Windows or the Web Client) does not “see” your vSphere Cluster the same way that vCenter “sees” all of the ESXi Hosts. Try to answer the following questions, and then we’ll get started with diagnosis. Continue reading “Diagnosing and fixing Virtual Machine Remote Console MKS problems”

Building a vSphere Home or Learning Lab – Part 2

In Part two, we will install the VMware vSphere Client for Windows, create forward and reverse DNS (which is a prerequisite for installing vCenter in any form) and then we will install the VMware vCenter Server Appliance (VCSA) to manage our ESXi VMs Continue reading “Building a vSphere Home or Learning Lab – Part 2”
