Almost one month ago, immediately after the VMware Partner Exchange conference, TechTarget published a scoop about some new features that may appear in the upcoming version of vSphere, expected later this year.

The list includes:

• Transparent Memory Compression
  This will avoid swap when RAM is overcommited by compressing a set of target pages to a special region. VMware measured the latency of this technique as a hundred times better than the latency of swapping on rotating disks. 
• IO-Resource Manager (IO-RM)
  This will allow the Distributed Resource Scheduler (DRS) to assign shares based on disk performance. The more shares a virtual machine will have, the higher priority it will get in accessing a shared VMFS volume.

The imminent launch of Intel octal-core CPUs (codename Nehalem-EX) and servers with up to 48 cores (powered by AMD codename Magny-cours CPUs) will dramatically increase the virtualization hosts density but will highlight how the network layer is becoming one of the weakest point of high-capacity virtual infrastructures.

Anandtech just published a very interesting article on this topic, testing the performance of a couple of copper cable 10GBase-CX4 network interface cards against the popular quad-port gigabit NICs we use today in most virtualization hosts.

The benchmark measured dual-port Intel PRO/1000 PT Server adapter (82571EB) against a Supermicro AOC-STG-I2 dual-port 10Gbit/s Intel 82598EB and a Neterion Xframe-E 10Gbit/s.
Both NICs were tested with VMware vSphere 4.0 Update 1 and CentOS 5.4 guest OSes with appropriate drivers.

The well-know virtualization professional (and blogger) Eric Sloof just released a tool called vmClient.

vmClient is a minimal management console that appears as an empty window frame.
It features a menu bar where the virtual machines hosted by any VMware vCenter Server or ESX/ESXi host are listed.
Each virtual machine in the list can be powered on/off, suspended and restarted. When the user tries to connect to them, the empty vmClient frame gets populated by the VMware MKS console (VNC) session with the guest operating system.

Archipel is a new open source virtual infrastructure management system based on the libvirt libraries and the Extensible Messaging and Presence Protocol (XMPP, formerly Jabber).

Still in early stage, the tool supports KVM, Xen, OpenVZ and VirtualBox and it’s currently able to operate single virtual machines and VM groups, displaying performance statistics about them.

The interesting twist is that, thanks to the XMPP engine, this console provides instant notification about VMs status to any chat client that supports the (almost) standard protocol.
This means that virtual infrastructure administrators can query virtual machine status through their IM program of choice (like Google Talk or Gmail Chat for example).

Microsoft just published the beta version of a new Infrastructure Planning and Design guide.
Titled Dynamic Data Center, this 43-pages blueprint on what Microsoft defines “a combination of automation, control, and resource management software with a well-defined topology of virtualization, servers, storage, and networking hardware”.

While Intel prepares to launch its first octal-core CPU (codename Nehalem-EX) , which will potentially trigger a price increase in vSphere licensing, VMware publishes a new benchmark on current Xeon 5500 servers.

This time the company focuses on high throughput web performance, running the SPECweb2005 benchmark against a HP ProLiant DL380 G6 machine equipped with two quad-core Intel Xeon X5570 CPUs @ 2.933GHz and 96GB memory.

The system above, powered by vSphere 4.0, run four virtual machines with 4 vCPUs and 21GB vRAM each, hosting a copy of paravirtualized 64bit Novell SUSE Enterprise Linux 11 plus Rock Webserver and Rock JSP server.

At the beginning of January virtualization.info published a long overview about the VMware’s approach to cloud computing, covering the vCloud APIs, the vCloud Express implementation and the five partners that are currently offering it.

One of them, BlueLock, just sent an email to its customers announcing that its vCloud Express offering will (tentatively) move from beta to general availability (GA) on March 25.

As far as we know none of the other providers is out of beta yet (this article will be updated if necessary).
So, while it’s entirely possible that BlueLock wants to be the first to announce vCloud Express GA, it’s much more likely that all the early adopters will make GA announcements in the same timeframe.
And this may mean that VMware is about to release some additional information or bits about its cloud computing platform. Like for example a version 1.0 of the APIs, or the public version of project Redwood, the software that will allow customers to migrate their virtual machines from their private virtual infrastructure to public clouds like the BlueLock one.

With an unexpected move, at the end of last week Parallels announced support for the upcoming Google operating system, Chrome OS, in its Desktop 5 for Mac.

While it’s entirely expected that consumers use desktop virtualization platforms to test new operating systems, it’s pretty uncommon to see a vendor that officially supports a beta product that is not widely deployed like Windows.

Considering the long beta cycles that Google products have (sometimes years), the effort to support multiple beta builds will be remarkable for Parallels.

The first stable release for Chrome OS is not expected to arrive before the second half of 2010.

Neocleus is a US startup that entered the virtualization market in May 2008 without much fanfare  (see virtualization.info coverage).
At that time, their Xen-based client hypervisor, Trusted Edge, was pitched as a secure endpoint platform that could be enriched by 3rd parties applications.

Two years after that, Neocleus still doesn’t get any significant traction despite many customers are well aware of (and very interested on) the client hypervisor concept because of its potential to deliver VDI in offline mode.
One reason for this lack of interest is that so far the startup made extremely complex to exactly understand the details of its product and to access it (the whole “drop us an email” argument doesn’t work well for a technology that is completely new and that faces severe skepticism about performance and hardware support).

Last week Reuters and other news outlets reported that the VMware’s board approved a plan to buy back $400M in Class A shares.

The operation will happen over the months, through the end of 2011.

EMC said it has no intention to modify its ownership of the subsidiary, keeping it at around 80%.

In another note, the VMware’s CFO, Mark Peek, sold 15,000 shares at an average price of $46.72 a share in mid-February.
