There is a great deal of marketing hype about which hypervisor is better but I have spent some thinking about this and really have to wonder if the hypervisor is what we should really be focusing or concentrating on. A lot of third party vendors are starting to port their products to be able to work with both hypervisors but what about the management server itself? When third party application vendors design their applications to work with VMware or Microsoft hypervisors they have been writing plug-ins for their product to work inside the management server systems and or its client.
PhD Virtual has gained its second round of funding with investment from Citrix amongst others as discussed within our post News: esXpress is no more but what does this mean for XenServer? Up until this point it looked like Citrix was out of the server hypervisor wars and backing Microsoft’s Hyper-V play. Yet this looks on the surface like a basic shift to that direction. Yes, XenServer was placed into the OpenSource community and the latest improvements, such as the Open VSwitch integration and a new releases emphatically say that XenServer is alive and well and that its ecosystem is growing for that matter so is Hyper-V’s.
The centralisation of desktop services can generate cost savings through simplified management and faster, more reliable implementation time. Desktop Streaming solutions such as Citrix Provisioning Services for Desktops and Double-Take Flex provide the option of centralising desktop images for delivery across your enterprise’s desktop solutions.

Just like a Telco, the ‘last mile’ of Virtualization is often the most difficult, I would say even more difficult than the initial phase of virtualization. What do I mean by the ‘last mile’?
The 5-10% of systems that you have LEFT to virtualize.
These systems are your most highly used, too X to virtualize, the most complex to migrate, dependent upon specific hardware, or travel around the world (such as laptops and other hand held devices). These issues are also highly political as well.
Many of us have to demo virtualization technologies to our customers and colleagues, run classes, develop code for virtualization, or just play around. For many of these cases, a cloud based virtual environment may be fine. However, what do you do when the network connection to the cloud is flaky at best? You have to rely upon your local system to do the job for you. Some solve this problem by having a ready slide deck, others solve this problem by using a fairly high end laptop, and still others tether their laptops to their phones and other cell phone cards. Which method is best?
I have always found local access to my laptop has always been the better way to run demos, classes, and presentations for my customers, colleagues, and friends. As I write software for and books about virtualized environments I almost always need access to various virtualization systems. Where I can I use network connections as going back to the office lab is in most cases much faster than local, but when I have to run things local due to telecommunication issues a high end laptop is a requirement. But which one?
We all know that ESXi is the future for VMware are regards their Hypervisor strategy, however most of you are more that aware of my dislike of the current interation. Now that I have got that off my chest, what has prompted this latest outburst?

I recently spoke at the InfoSec World 2010 Summit on Virtualization and Cloud Security and also attended the main conference sitting in on many Virtualization discussions. Perhaps it was the crowd, which was roughly 30-40% auditors. Perhaps it was the timing as SourceBoston was also going on, as well as CloudExpo in NY. But I was surprised to find that people are still ‘just starting’ to think about Virtualization Security. Since I think about this subject nearly every day, this was disappointing to me at best. I found ideas around virtualization security ranging from:
* Virtualization Security is not part of an architecture/design, what do I bolt on?
* My Physical Security will work
* Virtual Environments NEED More security than physical environments
* There are no new threats, so why have something more
* Security is a hindrance
I participated in GestaltIT’s TechFieldDay which is a sort of inverse conference, where the bloggers and independent analysts go to the vendors and then discuss the information they have received. We visited the following virtualization vendors:
* vKernel where we were introduced to their Predictive Capacity Planning tools
* EMC where we discussed integration of storage into the virtualization management tools as well as other hypervisor integrations
* Cisco where CVN and CVE were discussed in detail.
One thing I have learned in the time I have spent working in IT is that no software product, out of the box, will do everything that you want it to do. This especially goes for VMware’s vCenter Server. This is a great product but yet still has its shortcoming. vCenter will perform a lot of the tasks that we need to do and has the ability to report on a information we need to know about in our virtual environments but unfortunately not everything we need to know about can be easily found in bulk about multiple servers.
