August 19, 2008 by Robin Wauters 1 Comment

Stephen Spector published a post yesterday on the Xen blog featuring a proposed data sheet (PDF) for the upcoming Xen 3.3 release, which we said was in final testing stage in the beginning of this month.

Update 26 August: Xen 3.3.0 is available for download.

The complete list of new features in Xen 3.3 includes:

Performance and Scalability

CPUID Levelling
Shadow 3 Page Table Optimizations
EPT/NPT 2MB Page Support
Virtual Framebuffer Support for HVM Guests
PVSCSI — SCSI Support for PV Guests
Full 16-bit Emulation on Intel VT
Support for memory overcommit allowing more VMs per physical machine for some workloads

Security

PVGRUB Secure Replacement for PYGRUB
IO Emulation “stub domains” for HVM IO
Green Computing
Enhanced C & P State Power Management
Graphics Support
VT-d Device Pass-Through Support

Miscellaneous

Upgrade QEMU Version
Multi-Queue Support for Modern NICs
Removal of Domain Lock for PV Guests
Message Signalled Interrupts
Greatly improved precision for time-sensitive SMP VMs

Platform Computing Releases VM Orchestrator 4

August 15, 2008 by Robin Wauters Leave a Comment

Platform Computing has announced the next version of its virtual environment management product for the enterprise data center, Platform VM Orchestrator (VMO) 4. Platform VMO 4 provides faster delivery of virtual computer environments to end users while optimizing resource utilization, availability, and power consumption, to improve an enterprise’s return on investment from its virtualization environment. The solution offers a cost-effective enterprise virtualization management solution for Citrix XenServer, with support for virtualization platforms from other vendors to be delivered in the coming months.

Platform says VMO 4 increases IT productivity and responsiveness to business service levels through a Self-Service portal that supports delegated administration and allows end users to request and control usage of their own VMs without administrator involvement. At the core of VMO’s automated management is the multi-host dynamic resource management engine, which increases resource utilization across the virtual environment to remove bottlenecks and server silos according to flexible configurable policies that map to business priorities.

Platform VMO 4 will be available later this month.

IBM launches the open-ovf project

August 14, 2008 by Kris Buytaert Leave a Comment

Scott Moser from IBM’s Systems Technology Group has released the first version of the open-ovf project. OVF is a standard packaging format for virtual machines and software appliances. The open-ovf project is seeking contributors and users to help establish OVF as a transparent and platform-neutral method for packaging virtual machine images.

The goal of open-ovf is to be able to deploy a single OVF package to either Xen or KVM.
Eventually expanding that list to include VMware, Hyper-V, and other platforms. For that goal they are looking at community contributions. A good start might be the qemu-img tool that already knows how to convert between different formats.

The Distributed Management Task Force (DMTF) has defined a vendor-neutral standard for packaging virtual appliances enabling automated installation, configuration and activation of any virtualization platform. The Open Virtual Machine Format (OVF) specification describes an open, secure, portable, efficient and extensible format for packaging

For a summary of OVF and the open source project, see the presentation from the recent Xen summit
The open-ovf project is hosted on sourceforge and the source code is available from it’s git repository

Should VMWare Watch Out For VirtualBox?

August 14, 2008 by Kris Buytaert 1 Comment

Or for a lot more?

IT Wire has a good introductory article about VirtualBox.

Sadly their introduction is a bit wrong in the details, as VirtualBox obviously is not “the only professional virtualisation solution that is freely available as open source software under the GNU General Public License (GPL.) Why this matters is because it’s truly free, as in freedom.”

Amongst others Xen is also fully GPL, and given its backing from both Citrix and most of the major Linux vendors it’s also professionally supported.

Also it also isn’t the only one that can run unmodified guests , both KVM and Xen can do this, given the these days standard VT hardware support. VirtualBox however does not need VT support (and neither did Qemu).

However, it’s still a fairly good introduction and keeping these remarks in mind it’s a good read, and it shows that VMWare should watch its back, and not just for VirtualBox

Will Unidesk Bring Anything New to the VDI Table?

August 14, 2008 by Robin Wauters Leave a Comment

VMBlog is reporting that a new desktop virtualization management startup called Unidesk is about to break out of stealth mode. (note: the Unidesk website is still under construction as some titles and text snippets appear to be missing)

Founded in December of last year, Unidesk raised a total of $8.1 million this year from Matrix Partners and North Bridge Venture Partners. It has a strong management team, and recently opened up a second office in India next to their existing Marlborough offices. Their core offers are named “Composite Virtualization^“ and “Desktop Management 2.0” and they claim it will dramatically simplify desktop management for enterprise IT organizations.

“Building on a core invention called Composite Virtualization™, Unidesk will offer IT organizations the desktop control they’ve been seeking to reduce costs, improve service levels, and tighten security, while, at the same time, give lines of business the desktop freedom they require to maximize knowledge worker innovation and productivity. Unidesk’s family of “Desktop Management 2.0™” solutions will provide the highly efficient image management, application delivery, and personalization capabilities that are currently missing from Virtual Desktop Infrastructure (VDI) products from VMware and Citrix, and extend these same capabilities to non-VDI-based laptops and thick desktops so IT can easily support off-network computing. By eliminating the barriers to VDI adoption and enabling all desktops to be virtualized under a common management platform, Unidesk’s game-changing technology will accelerate the multi-billion dollar desktop virtualization market, and deliver significant returns to employees, investors, customers, and business partners.”

There’s not much else we can gather from the website, apart from the fact that the company is planning a free trial version, and that they’re hiring a bunch of people who will get – at least- a free mug (see here).
