News: Citrix Acquires

Citrix has purchased and this poses some interesting changes to the overall virtualization and cloud markets. One also has to wonder about the timing of the announcement to coincide with the same day as the big announcements coming out of VMware. I see this purchase as a mixed blessing to the market place, but also a renewal for Citrix.

OpenStack on Hyper-V – Microsoft does Public Cloud Interoperability

On October 22nd, Microsoft announced that it has partnered with to provide integration and support of Windows Server 2008 R2 Hyper-V to the OpenStack project. The announcement caused a great deal of interest here at the Virtualization Practice, as it signals an unexpected willingness on Microsoft’s part to pursue interoperability at the IaaS layer, allowing users to break out of the Hyper-v stack, whilst still retaining Hyper-v at the bottom. The fact this announcement came from Microsoft (not, Rackspace or OpenStack) seems to signal the seriousness of the intent.

In practical terms this means that puts a Hypervisor Abstraction Layer into the bottom of the OpenStack compute platform (Nova), and binds Hyper-V into that, to allow images to be deployed to and controlled on Hyper-V from OpenStack, using tooling that speaks one or other of the two OpenStack APIs (Native or Amazon EC2). Technically it is not a major step because although the initial version of Nova targeted libvirt and thereby Xen, KVM and Qemu, Citrix had already succceeded in providing a hypervisor abstraction layer in OpenStack for XenServer.

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.

More on OpenStack –, GPL, Citrix, Oracle and the DMTF standards.

If there was an annual prize in the PR industry for the best press release about a “Turkey really looking forward to Thanksgiving”, then it should be won by the PR from as it announced its participation in OpenStack.’s only asset is an GPL-licensed Open Source IaaS Cloud platform which it sells under “Open Core” licensing (more on this below).  If OpenStack succeeds, this asset is worthless.

However, if you look a little closer, it is clear that the canny investors at have a plan – just before the company becomes completely worthless, sell it for ridiculous amounts of money to Citrix. Surely that won’t work?
