I was tinkering around with XenServer the other day. I know I can hear you saying “is that a thing?” Well, it is, but this is not what I am going to talk about today. Time for a tangent shift. I thought I would have a look for a third-party switch for XenServer, but it…

Nutanix, one of the fastest growing IT infrastructure startups around, shows no signs of slowing down with their release of Nutanix OS 3.5. For those not familiar with Nutanix, they offer a truly converged virtualized infrastructure. This generally consists of four nodes in two rack units of space, where each node has CPU, RAM, traditional fixed disk, SSD, and Fusion-IO flash built in. Their secret sauce is really NDFS, the Nutanix Distributed File System, built by the same folks that created Google’s File System, as well as a unified, hypervisor-agnostic management interface.
The future of OpenStack looks bright, and with the all the software-defined data center (SDDC) features contained in the recent release of “Grizzly” they are now ready to compete toe-to-toe with heavyweights like VMware, Nutanix, Dell, and HP. Whether they can start unseating VMware products in the enterprise remains to be seen, though. Despite the immediate SDDC advantage of OpenStack, companies and technologies like that of Nicira and Virsto, both acquired by VMware, are not to be ignored.
Moving to the cloud! Let me be a little more precise and say moving to the public cloud. This concept has really been embraced and thrives in the consumer area but will this concept really take off in the corporate world and really should it? One of the main concepts of virtualization, in the beginning, was the ability to consolidate physical systems into a virtual environment to shrink the overall foot print size as well as being able to take advantage and use all available compute resources available in a physical server and having centralized control of the compute, storage and networking resources.
When it comes to public cloud computing services that old adage of “fast, cheap, or good – pick any two” certainly hold true. Amazon can offer you cheap, and since they own their stack, a rapid cycle time DevOps approach to support. But you are not going to get enterprise grade service level guarantees for Amazon’s pricing. To get both agile responsiveness and enterprise grade SLA’s you are going to have to give up on cheap.
Open Source continues to be an important part of the mix in Virtualization and Cloud. Indeed, this year has seen major developments in established players at the Operating System and Hypervisor level, as well as a major new cloud entry at the IaaS cloud layer.

During the Virtual Thoughts podcast on 6/29/2010, the analysts discussed various hardware aspects of virtualization trying to determine if the hypervisor was to move into the hardware? and if so how much of it? as well as whose hypervisor? and lastly such a move part of any business model?
Virtual Thoughts is a monthly podcast that looks at the entire scope of virtualization to discuss new trends and thoughts within the virtualization and cloud communities.
This weeks podcast started with a discussion of TPM/TXT and the boost it gives to virtualization security. Since TPM/TXT is based in the hardware and provides a measured launch of an operating system, the next logical discussion was on whether or not the hypervisor would be placed into the hardware?
As of Service Pack 1, SUSE Linux Enterprise Server 11 (SLES) supports KVM for SUSE guests. This post follows on from our previous post regarding the demise of Xen in Red Hat Enterprise Linux, and perhaps suggests the beginning of the end for Xen-based virtualization in Linux, but the story is far from clear. A complex set of agreements with Microsoft mean that Novell is bound to preferentially support Windows guests, and it may be a while before KVM support is adequate, although Novell has a project called Alacrity to help get it there. In the meanwhile Novell may get split up into pieces by a private equity house and SLES find itself a new owner.
