Virtualization

Kit FUI is a new site devoted to those cool (and fictional) user interfaces you see in movies and on TV

The concept behind server virtualization is simple - you have a powerful piece of hardware that no single application or service can fully utilize, so you allocate many smaller servers (virtual machines) to run simultaneously on a single device.

If you’re leasing server equipment in a hosting provider’s data center, you’re likely paying through the nose for antiquated technology. There is peace of mind that comes with that service in the form of care free hardware maintenance, but is that really enough to keep you paying for that same 4GB of RAM every month for life?

How often have you as a mobile web developer struggled to diagnose a style or layout issue on a particular device through trial and error? Wouldn’t it be so much easier if you could just inspect the DOM on the mobile device as you would on the desktop through Chrome or Firebug? It turns out there is a tool for that.

A customer recently switched from VMware Server to KVM, but we wanted better networking, which required us to install and operate the Open vSwitch.

In order to increase the size of my virtual environment, I need to increase the size of my primary storage. The choices were to increase the capacity of disks for slower disks, add another disk tray to my SAN, or to use a virtual storage appliance (VSA) within vSphere. I chose to go the route of a VSA. Here's how I did it:

Upgrading to the latest Veeam Backup and Replication v6.5 went smoothly. However, I got errors on all but one of my backup jobs. A simple patch fixed that.

1TB is just not enough for everything I have.

Ever since I upgraded vCenter Server to v5.1, my backup tool has been failing, unable to connect to vCenter. This is not unexpected as my SSL certificate for vCenter changed, and with that change comes the need to fix my backup tool. How to do this is fairly straight-forward actually.

vCloud Director was one of the easiest upgrades but still required some VMware Knowledge Base articles to complete. As always before you do anything you need to "Read the Fine Manual". One misstep may mean starting all over again.

Moving to vCenter 5.1 comes with quite a few caveats and requirements -- and if you make even one mistake you need to start over.
