What Happens When Chuck Norris Divides By Zero? – Virtualizing Virtualization

Posted on by

Sometimes you really can have too much of a good thing. Or is it? I’ve had a few specific use cases come up (demos for Virtualization Congress) where running one virtualization platform, on another virtualization platform makes sense (There will be instructions released on doing this closer to the show). Suffice it to say the

It Still Doesn’t Work – Windows 2003 Standard 32bit & 4 GB Ram

Posted on by

I’ve run across several cases recently where assigning 4GB of memory to a 32bit VM caused some concern by folks looking at what’s available in the system properties. Example:   The VM is set to use 4GB ram (4096MB) & Booted. Properties show less than 4GB As does Task Manager So why is this? It’s

OpenSuse 11.1 on VMware Workstation – vmware-modconfig

Posted on by

It’s not often you’re likely to see a VMware Workstation post here. Why? Because for my limited use case, it “Just Works”. Really, it just does. This weekend however, I had some minor issues, why? Well, at some time on Friday (Saturday?) my Ubuntu 8.04 host install gave up the ghost. Some update or another

Windows VM? Performance Gone to Heck? – Check Some of These Non Obvious Places

Posted on by

It’s late on a Friday. You’ve just virtualized this workload app server, and now it’s gone straight to hell. No, it didn’t pass go first either. You go through the motions of checking the host, knowing that you triple checked it the first time before putting the workload on there. You verified that you’re not

Upgrades! My Office, Your VMware Tools.

Posted on by

This last weekend, the WordPress install on the site wasn’t the only thing that got an upgrade. The Professional VMware ‘offices’ got an upgrade as well. I’ve upgraded from a monolithic old wooden eyesore of a desk to a larger, aluminum & glass setup, that I think is just stylin. Take a look:   Enough

Managing VI with PowerShell Presentation – What Do You Want To See?

Posted on by

Since y’all voted me and Pancil into the Virtualization Congress. I figure y’all should have some input into the presentation. Keep in mind, we’ll not just be covering managing VMware VI with PowerShell, but we’ll also cover managing Xen & Hyper-V too. Anything general? Anything specific? A particular use case you’d like to see? Leave

The Religion of Virtualization

Posted on by

I never thought of it this way, but alas, this weekend, a few folks have spent quite some time on it. It started with Brenda at Virtual Gipsy: Of the things I learned while studying anthropology, the one that stuck most was to always pay attention to that which stands out. Unexpected behavior, words that

New Book! – VI3 Implementation & Administration

Posted on by

This book is now officially on my wish list. Dead tree, PDF, doesn’t matter. More and more companies are choosing to virtualize and consolidate their server environments with VMware to achieve smaller footprints and reduced operating costs, but optimizing the virtualized environment is nearly impossible without a solid strategy in place. This complete guide to

Ubuntu Cloning – Mac Address Change Mayhem.

Posted on by

Apparently networking in Ubuntu goes funny when you change it’s Mac Address, and picks up the changed MAC as a new NIC, and assigns it the next number sequentially. While you can get around this by statically setting the MAC address, you generally want to avoid that. Having duplicate MAC addresses is a “Bad Idea”
