The Virtualization Practice

Tag Archive for Xen

Stefano Stabellini, a senior software engineer at Citrix Systems, has announced a proof of concept port of the open source Xen Hypervisor for the ARM Cortex A15 processor. The project was started in early November and has already developed to the point where it is capable of booting a Linux 3.0 based virtual machine up to a shell prompt. The Xen port has progressed so rapidly due to a decision to take advantage of the virtualization features that were introduced with the ARMv7 architecture making it small and comparatively easy to develop. However, because of this it won’t be able to run on anything older than a Cortex-A15 processor.

As a delegate for Tech Field Day 6 in Boston, I was introduced to many third party management tools. In the past I have been given briefings as well on various VMware, Hyper-V, and Citrix Xen Management Tools as well. Many of these tools are marketed directly for use by the administrator, but they have the tools can be used by more than the administrator. These tools should be marketed to management, administrators, as well as the network operations center (NOC). We need tools that perform continual monitoring and auditing so that we can know as soon as possible when a problem occurs.

At Citrix Synergy 2011 in San Francisco last month Simon Crosby made the case that the biggest barrier to the adoption of service-provider offered cloud services is the understandable lack of trust on the part of enterprise customers. Well it looks as if he and fellow Xen luminary Ian Pratt have decided to do something about that lack of trust and are moving on from Citrix to address the problem at its source. Ian and Simon announced today that they are both leaving Citrix and taking key roles along with with Gaurav Banga (the creator of Phoenix Hyperspace) as co-founders of cloud security start-up Bromium.

Mainstream virtual desktop solutions have focused their efforts on providing the best platform for hosting virtual desktop environments. Hypervisors, image management, and connection brokers are the top feature sets that companies have looked at during their comparisons. Moving up the stack, these vendors are now focusing on user personalization management, but do not have what is considered to be a full desktop management solution. So are our end-to-end virtual desktop solutions really complete?

The Virtualization Security Podcast on 10/7 was the second in a series of Virtual Desktop Security discussions we will are having. The special guest panelist was Simon Graham of Virtual Computer, the makers of NxTop a client side hypervisor based on Xen. On this podcast, we went into the details of NxTop.

The engineers at Virtual Computer have thought about nearly everything when it comes to a Client Hypervisor. NxTop operates as a standalone or as a centrally managed client hypervisor. The difference is fairly stark. I feel that most people in the Enterprise unless this is a one off situation would want to use the managed client hypervisor.

There has been a lot of noise about a negotiations between VMware and Novell, rumors are that it regards the purchase of the SUSE division, now firstly every thing that follows is pure supposition on my part, I have no insider knowledge. now mike has put forward one argument on why a VMware purchase of Novell SUSE assets make very good corporate sense. However I put another idea into the fray.

VMworld is clearly the largest dedicated virtualization conference, and yet from an Open Source perspective it is slightly disappointing because the VMware ecosystem naturally attracts proprietary software vendors, and also some of the more interesting activities in Open Source are through multi-vendor foundations which do not have the same marketing budgets as vendors themselves.

Nevertheless, there are a number of key Open Source players, and some interesting smaller players, represented at VMworld.
