The Virtualization Practice

Microsoft’s announcement yesterday of Massachusetts based Sentillion extends its reach into healthcare solutions and added a new component to its virtualization portfolio. Sentillion’s vThere is a type-2 hypervisor (hosted virtual machine) built on Parallels virtualization whose strength is in its ability to provide a highly secured desktop image on a normally non-secured solution.

75% of users report using VMWare today, and nearly 2/3rds report having tested an alternative hypervisor with Microsoft Hyper-v and Citrix Xen most often mentioned. Of those who have tested an alternative, 27% plan to use the it, while an additional 20% report that they may use it. Only 2% of VMware customers plan to switch to an alternative additional 9% considering it.

Microsoft and Red Hat Cross-Certify to try and get VmWare out of the Datacenter. Red Hat Enterprise Linux 5.2, 5.3, 5.4 has passed certification tests when running on Windows Server 2008 Hyper-V, Microsoft Hyper-V Server 2008 and Windows Server 2008 R2 Hyper-V, Microsoft Hyper-V Server 2008 R2.
Windows Server 2003/ Windows Server 2008 / Windows Server 2008 R2 are validated to run on RHEL 5.4, using the KVM-based hypervisor.

In the fog of the datacenter virtualization war, it is difficult to see clearly who will end up on top, and yet the outcome is almost certainly determined, and the victorious generals are even now moving on to fight new battles. Here at the Virtualization Practice we too would like to think we can see through the fog to work out who has won, so here are our thoughts, take account of them as you wish. They concern, primarily, the big four protagonists: Microsoft/Hyper-V, Citrix /Xen, VMware/vSphere and Red Hat/KVM.

There is quite a bit of documentation on bare metal or Type 1 hypervisors, including my own book, VMware vSphereTM and Virtual Infrastructure Security: Securing the Virtual Environment, but there is not much material on the proper security of hosted environments, or Type 2 hypervisors, such as Microsoft Virtual Server, VMware Workstation, Fusion, Player, or Server as well as Qemu, Virtuozzo, or OpenVZ.
