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”

VMware vSphere 6 is finally ready!

Unlike in previous releases, VMware took a good long time getting vSphere 6 ready. For the first time ever, VMware made the Beta version of vSphere 6 publicly available (all you had to do was sign-up) and was actively soliciting input on the Beta forums.

The initial public release of vSphere 6 (3/12/2015) was, nonetheless, plagued with at least one critical issue and several annoyances. The most critical issue affecting vSphere 6 was that Changed Block Tracking (CBT) appeared to be essentially broken, rendering most forms of backup using the vSphere API for Data Protection useless[1]. This and other less significant issues rendered the initial release of vSphere 6 unsuitable for use in production environments, and I recommended that all users hold off on upgrading until these issues had been resolved.

10 Questions you should ask your DR provider

There has been a ton of misinformation surrounding legitimate Disaster Recovery for Virtualized environments. There are many purveyors of “all-you-can-eat DR to the Cloud” for very attractive blanket rates such as $600.00/month. Other providers offer “per-VM to the Cloud” protection in the sub $20.00/month price range. Continue reading “10 Questions you should ask your DR provider”

Cloud permissions for VMware vSphere (Roles, Privileges and Permissions)

VMware vSphere offers powerful native tools to manage users’ access to resources in a vSphere environment. Administrators may create custom Roles that are composed of one or more granular Privileges. Each Privilege is the most granular right that can be ascribed within vSphere, such as the ability to power-on a virtual machine (NOTE: power-off is a separate privilege!).
