Quoting from the Egenra official announcement:

Egenera Inc., a global leader in datacenter virtualization architecture, today announced that the U.S. Patent and Trademark Office has issued U.S. Patent No. 7,174,390 entitled, “Address resolution protocol system and method in a virtual network.”

…

Address Resolution Protocol (ARP) within conventional Ethernet networks associates server and application IP addresses with their Ethernet addresses. In systems such as the Egenera BladeFrame system that emulate Ethernet semantics on a high-bandwidth, low-latency, point-to-point fabric, virtual circuits in the fabric direct traffic flow. Typically, it is necessary to further convert Ethernet addresses into virtual circuit numbers whenever traffic is sent—adding an extra table look-up for each transmission. Egenera’s invention obviates the extra step by combining the virtual circuit table with the ARP table, lowering latency and processing overhead…

ComputerWorld published a brief but interesting comparison between Apple Mac OS most popular virtualization solution, Parallels Desktop, and the upcoming solution from virtualization market leader, VMware codename Fusion, providing following conclusion:

Both Parallels Desktop and VMware Fusion are good products. However, it is clear that Fusion still needs some work in terms of its performance and to fully implement its feature set. It also isn’t quite as stable and reliable as Parallels.

…

It is also worth noting that the next release of Parallels is slated to offer at least two of those features — drag and drop and USB 2.0. It is also slated for several more advances including the ability to use a Boot Camp partition as a Windows boot disk instead of a hard drive image file, greatly enhanced network options and full support for CD/DVD drives (including burn capabilities and access to copy-protected discs). There will also be a new mode called “coherence” that will allow Windows applications to run alongside Mac applications without the need for a separate Windows interface…

As a result, it seems that for the foreseeable future, VMware will remain a generation behind Parallels.

Despite the unfair competition (VMware codename Fusion is still in beta), which has been admitted by reviewer, conclusion is relevant: Fusion has been annouced since August 2006 and still has to reach Release Candidate status. Before such milestone Parallels is expected to release Desktop 2.5 and to already start working on 3.0 beta.

The VMware Performance Team posted on its corporate blog some results obtained comparing ESX Server performances in NUMA and non-NUMA architectures:

recently performed some NUMA characterizations using VMmark on an older HP DL585 with 4 2.2 GHz dual-core Opterons. In the DL585, each dual-core processor is in its own NUMA node. I wanted to measure how heavily we stress the NUMA interconnect links, known as HyperTransport (HT) on the Opteron. I ran tests with one VMmark tile (6 VMs), two VMmark tiles (12 VMs), three VMmark tiles (18VMs), and four VMmark tiles (24 VMs). The tests consumed 27%, 58%, 90%, and 100% of the system CPU resources, respectively.

…

The most important result is that the HT utilization remains below 20% in all cases. This implies that we have a large amount of headroom in the memory subsystem, which can be used as processor speeds increase. More importantly, the transition to quad-core systems should also be smooth, especially since newer versions of the HT links should provide even better performance.

…

I then repeated the experiment with the DL 585 configured in memory-interleave (non-NUMA) mode in order to quantify the benefits of using NUMA on this system…The tests also consumed slightly more CPU resources than the NUMA configuration at each load level due to the higher average memory latencies caused by the high proportion of remote accesses. The average CPU utilization was 30%, 62%, 95%, and 100% with 6 VMs, 12 VMs, 18 VMs, and 24 VMs, respectively…

VMware continues to collect successes with ESX Server 3 and VirtualCenter 2 powerful combination.

In January 2007 products has been named Disaster Recovery solution of 2006 by SearchWinComputing.

In February 2007 the bundle has been named first product for building the New Data Center by Network World.

Is this the best moment to use IT 2.0 hype for virtualization marketing?

Quoting from the Double-Take official announcement:

Further broadening its offerings for VMware environments, Double-Take® Software today announced Double-Take for VMware Infrastructure, a solution that protects entire VMware virtual machines.

…

Double-Take for VMware Infrastructure runs on a single Windows® server in a virtualized environment, and allows administrators to centrally manage and monitor multiple virtual machine protection jobs from any Windows desktop using the client management console. Double-Take for VMware Infrastructure captures changes regularly, keeping the target virtual disks up to date and ready for failover, recovery and backup at any time.

Double-Take for VMware Infrastructure is compatible with VMware ESX Server versions 3 and later, and VirtualCenter version 2 or later.

Quoting from the SWsoft official announcement:

SWsoft, Inc. has signed an agreement with Microsoft Corp. that helps SWsoft enhance its customers’ experience. The agreement is for a three-year period and benefits SWsoft enterprise and hosting customers running Virtuozzo for Windows Server virtualization software.

…

As part of the agreement, SWsoft will receive 24-hour, 7-day support from Microsoft for its enterprise and hosting customers operating Windows-based applications within Virtuozzo virtual environments…

The russian startup Veeam continues to release free tools to simplify VMware power users’ life.

After Veeam Monitor (which is free when used with VMware Workstation) and Veeam FastSCP, the company launches Veeam RootAccess:

By default ESX Server 3 does not allow remote shell access (ssh) for the root account. Veeam RootAccess Wizard helps you to enable or disable remote root access, or create a regular non-root user account. The newly created non-root user will belong to the default ‘users’ group and will be automatically granted remote ssh access. Su or sudo commands can then be used to elevate to the root account for privileged operations.

After launching its own virtual appliances delivery facility and bundling for the first time an appliance with its plaftorm, Virtual Iron (in collaboration with rPath and the Barton Group) is arranging a new webcast about the topic for February 21th:

The growing acceptance of virtualization technology is about to revolutionize the way IT consumers deploy applications. A major part of this shift is being driven by software vendors who provide “virtual appliances.”

Virtual appliances represent a new opportunity to streamline and simplify software distribution for virtual environments. With a virtual appliance, software vendors can ship thoroughly tested, standard configurations that require minimal installation effort. Users are spared the complication of installing multiple supporting systems, since everything is contained in the virtual appliance package — the operating system, services and applications. This dramatically decreases potential support issues related to incorrectly configured software or hardware. Users can simply download the virtual appliance and run it with virtualization software.

In this online panel discussion, industry experts from the Burton Group, rPath and Virtual Iron will discuss best practices in virtualization and the use of virtual appliances.

Attendees will learn:

• Best use and deployment of virtual appliances
• Leveraging ready to run virtual appliances that you can take advantage of today
• Using virtual appliances to enable maximum operational efficiency and the smallest hardware footprint possible

After 4 years since Virtual PC 2004 and 4 months since first public beta Microsoft finally release Virtual PC 2007, probably the last virtualization platform based on Connectix technology before the launch of brand new Windows Server Virtualization (codename Viridian).

This new version is released free of charge like Virtual Server 2005 and introduces some notable improvements like:

• 64bit host OS support
• AMD SVM and Intel VT support
• Vista support (both host and guest OS)
• PXE booting support

but continues to lack on some critical aspects like 64bit guest OSes support.

Anyway the biggest change in this release is dropping of support for Windows 95 (while support for OS/2 Warp is still there).

This may seem a contraddiction: one of the first purposes of virtualization was supporting legacy applications and environments, and Microsoft more than anybody else on the IT industry could benefit from it to grant extended support to its customers. Instead it’s the market leader and competitor VMware which provides such support.
