What Do You Think When You Hear The Word Host?

When you hear the term “host” when talking about virtual environment, what is the first thing you think of? For me, the answer is simple, a host is an appliance. For years now I have been standing on my soap box and preaching the power and fundamentals of automation in building and configuring your virtual environment. I came across a thread on the VMware VMTN Community Forum where a concerned individual was in a position that he was going to have to rebuild his host from scratch. What he did to get himself into this position was to run a hardening script on the host and then the host became broken and unusable. This person was concerned that he did not have a backup of the host and was looking for a way to rollback.

Microsoft Enterprise Desktop Virtualization – MED-V: Just a Band-Aid Solution?

Is Med-V only a ‘point solution’ to ease migration or can you use that functionality to a wider audience to solve other problems? When considering Med-v as part of MDOP, is it a useful client hypervisor tool for reducing desktop management costs.

vSphere 4.1 and ESXi

Unless you have been on vacation or hiding under a rock then you have heard the latest buzz in the industry that vSphere 4.1 has been released. There have been a lot of blog posts on the topic already. You can find one example here, here and what we at virtualizationpractice.com posted here. The thing I want to hit on for this post is the fact that this release will be the last release for full version of ESX. Moving forward on any new releases of ESX will be strictly ESXi. Anyone that knows me over the years knows that I have not really been a big fan of getting rid of the full version ESX Server. Call me old school and the fact that I have spent a great deal of time developing the automation used in the environments that I have supported over the years and have been really happy with what I was able to accomplish via kickstart and bash.

vSphere 4.1 Released – More Dynamic Resource Load Balancing

With the release of vSphere 4.1, VMware has added to their Dynamic Resource Load Balancing (DRLB) suite of tools that I hinted at in my post on Dynamic Resource Load Balancing that I wrote last week as well as providing new memory over commit and other functionality. In essence, vSphere 4.1 is more than a point release, this update includes many features that aid in security, reliability, and is a direct response to customer requests.

Safe way to Encrypt within a VM – Need for Technology

Encryption is important, encryption within a VM even more important. But the question is how to do this securely without allowing the encryption keys to be seen by an administrator of the virtual environment and that supports vMotion or LiveMigration. The solution is per VM encrypted memory, but something more robust that makes use of hardware, out of band key exchange, and supports vMotion or LiveMigration.
