Red Hat turning VMworld into KVMworld?



Posted by: Colin Steele
Red Hat, Colin Steele, VMworld 2009, KVM, Open source, Citrix, Microsoft

VMworld 2009 is still two months away, but at least one virtualization competitor is already planning to steal some thunder at the show.

The Red Hat Enterprise Virtualization (RHEV) suite will hit general availability Sept. 1, according to LeMagIT — which, for those of you who don’t parlez francais, means “The IT Mag.” Sept. 1 is the first full day of VMworld 2009, when VMware typically makes most of its major announcements.

RHEV marks a shift from Xen to KVM as Red Hat’s open source virtualization technology of choice, as senior virtualization director Navin Thadani said on last week’s edition of This Week in Virtualization.

Virtualization security fears grow

Why choose server virtualization?, Virtualization security, IBM, Microsoft, Colin Steele

As people who deal with virtualization every day — you work with it, I write about it — it’s easy to get caught up in the idea that it’s a ubiquitous technology with infinite use cases and unending appeal.

Well, in the words of Lee Corso:

Lee Corso

There are still quite a few people out there who don’t feel totally comfortable virtualizing everything. And they’re not all newbies who don’t know what they’re talking about.

Virtualization: Why Microsoft cares



Posted by: Ken Cline
Virtualization, Microsoft

Have you ever wondered why Microsoft cares so much about server virtualization? After all, it’s only a software representation of a physical machine.

Microsoft has been very content over the last nearly 30 years letting the likes of Dell, Hewlett-Packard and IBM build physical servers with nary a care. When VMware introduced commodity server virtualization back in 1999, Microsoft hardly batted an eye. So what’s happened to make Microsoft not only care, but care enough to invest millions of dollars into their own server virtualization solution?

It’s all about control.

Key concepts of Hyper-V Integration Services



Posted by: Rick Vanover
Microsoft, Virtualization platforms, Rick Vanover, Microsoft Hyper-V

Integration Services is Microsoft Hyper-V’s installation interface on guest virtual machines that is designed to optimize the drivers of the virtual environments and provide the best experience. Here is a rundown of what you want to know about Integration Services when getting started with Hyper-V.

  • Integration Services are installed via virtual CD - For default installations, the C:\windows\system32\ path of the Hyper-V server contains the guest.iso file. This virtual CD provides the installation of Integration Services and is launched from the Action menu on the virtual machine as shown below:

Hyper-V Integration Services

  • Integration Services are native on some platforms - Selected releases of Windows Vista and Windows Server 2008 are Integration Services aware and do not need to be installed specifically.
  • New Services and the Control Panel - Integrations Services shows up as Hyper-V Guest Components in the Control Panel and installs five Windows-based services. These are Hyper-V Data Exchange Service, Hyper-V Guest Shutdown Service, Hyper-V Heartbeat Service, Hyper-V Time Synchronization Service and Hyper-V Volume Shadow Copy Requestor. These Windows-based services exist in the task manager as vmicsvc.exe.
  • Ease of Use - The installation of Integration Services permits the full use of Hyper-V Manager through remote desktop connections. Without this installation, interaction with the guest VM within Hyper-V Manager through a remote desktop from a different system will not permit mouse use.

Installing the hypervisor driver packages, such as VMware Tools, VirtualBox Guest Additions or Hyper-V Integration Services is always a wise decision in order to optimize the experience for guest systems. The configuration and setup of Integrations Services is very light, and can be managed much like the other driver packages. More information on Hyper-V can be found on the Microsoft website.

Still mulling over a Greene-less VMware



Posted by: Joseph Foran
Uncategorized, Storage, Microsoft, Virtualization, Joseph Foran, Microsoft Hyper-V, Citrix XenServer, VMworld 2008

It’s been covered to death, but something about Diane Greene’s ousting from VMware’s top spot still doesn’t sit right with me. Not the ousting itself but the chatter about why. There have been conversations about why she was let go, ranging from EMC’s CEO Joe Tucci wanting greater control of VMware to questions about whether she was more of a technology person and less of a business person. In the end, the appointment of Paul Maritz is the really big news, at least in my not-so-humble opinion.

It goes back to “it’s not what but who you know,” and Maritz knows Microsoft. He knows Ballmer, Gates and every other player there. He was one of the most influential and instrumental executives in Microsoft’s history. His reach is wide when it comes to pulling people into the fold — not necessarily by bringing ex-Microsoft folks in as employees, but rather by having high-level working relationships with all the partners that Microsoft has worked with and that EMC and VMware have worked with or would love to work with. He also knows the PC Revolution firsthand, having seen the rise and fall of Novell’s NetWare, Banyan’s VINES and the host of minis and mains that these replaced, only to be replaced by Windows a few years later.

Tucci also knows Microsoft — EMC’s storage products center around the Microsoft world as much as any other operating system. Exchange data stores, SQL databases, file shares — all of these are EMC’s bread and butter in selling storage to the modern data center. Its software, even though some products compete (like Documentum versus Sharepoint PS), is built around a Windows-centric world.

Then there’s the history — Microsoft knows how to win. It buys what it can’t make on its own, then drowns the competition in price wars and advertising battles. Novell, once Microsoft’s bitter rival for network OS sales, now sells Linux licenses to Microsoft. Netscape is gone and the ghost of its second cousin twice removed, the Mozilla Foundation’s Firefox, lives on to take what is really an insignificant chunk of Internet Explorer’s market share. Corel/Novell WordPerfect? Only if you’re working in a huge law firm will you see WP on an enterprise level.

Put these together and the fabled VMware versus Microsoft Hypervisor war starts to look less like an armed conflict between bitter rivals and more like a strategic partnership built through a demonstration of independence. Tucci’s no fool — Maritz is there for the day that the Redmond giant comes knocking. He’s there to build thin but sturdy roads between the two companies. He’s there to forge something like the Citrix/Microsoft alliance, where Citrix is an independent company but still acts in many ways like a subsidiary of Microsoft (or at least an extension). In Martiz’s VMworld keynote speech (not the parts about having “sins to atone for” in his early days of programming for the PC Revolution), he barely mentioned Greene and hardly touched on competition with Microsoft. He’s looking forward to the day when he can do what only Citrix has managed to do so far — preserve independence while under Redmond’s all-seeing eye.

In the end, we’ll see VMware’s VDC-OS as the dominant force in the virtualization space with Hyper-V as an acceptable but lesser alternative, much like Citrix’s MetaFrame/XenApp and Microsoft’s Terminal Services. I think this leaves one question: In the long run, what happens to Citrix now that it’s betting so heavily on Xen and taking on Microsoft and VMware directly in the systems virtualization market?

ThinLaunch not all that impressive



Posted by: Joseph Foran

At the New Innovators both at VMworld 2008 was an interesting small booth from ThinLaunch, which was manned by three of the four people in the company. I had a short pow-wow with two of the folks there and came away with mixed feelings. The product, for which the company is named, appears to fulfill a couple of interesting needs, the first being IT shops that want to pilot virtual desktop infrastructure (VDI) but don’t want to invest beyond the server room, and the second being smaller businesses that have server virtualization capacity to devote to hosting clients but have been loathe to rip and replace their thick clients with new thin hardware. I’m not too wowed by the product but I can see where it may be useful. That said, I was royally unimpressed with the technology.

ThinLaunch can be cobbled together with a few Group Policy object edits in Active Directory without buying the product. Simply replace the shell with whatever VDI launcher (or other application) you want. Microsoft tells you how to do it here. True, ThinLaunch then monitors this process if it crashes and can automatically restart it, but this is also something that can be managed with an application or by copying the code from this site.

ThinLaunch is available as an MSI package, meaning it’s very easy to deploy via Group Policy. Then again, Group Policies are even easier to deploy via group policy. Duh. ThinLaunch requires .NET 2.0. and GPOs don’t. ThinLaunch supports Windows 2000 through Vista and 2K8. GPOs do too.

I can see the need for this package and I can even see some large enterprise customers who’d want a packaged application to handle the conversion of legacy desktops. I can even see using the product in small businesses with virtualization already in place but a lot of legacy desktops and a lack of cash. What I can’t see is how it’s innovative in its approach.

Sorry, ThinLaunch, but you get three out of ten pokers — there’s just nothing hot there.

Microsoft’s Hyper-V bundling with Windows Server 2008: Deja vu?



Posted by: Bridget Botelho
Microsoft, Virtualization, VMware, Windows Server 2008, Microsoft Hyper-V, Citrix XenServer

You may recall the 1998 anti-trust case in which Microsoft Corp. was sued by the U.S. for bundling Internet Explorer with its Windows operating system, because doing so gave Microsoft an advantage that led to the demise of the incumbent Web browser, Netscape Navigator.

Fast-forward 10 years to today. Microsoft bundles its Hyper-V hypervisor with Windows Server 2008, so anyone who uses Windows Server 2008 also gets Hyper-V.

Is this déjà vu?

Just for fun, let’s play a little game. In the Wikipedia definition of United States v. Microsoft, let’s replace “Web browser” with “hypervisor,” “Netscape” with “VMware,” and “Internet Explorer” with “Hyper-V.”

Here we go:

United States v. Microsoft 87 F. Supp. 2d 30 (D.D.C. 2000) was a set of consolidated civil actions filed against Microsoft Corp. on May 18, 1998 by the United States Department of Justice (DOJ) and twenty U.S. states. Joel I. Klein was the lead prosecutor. The plaintiffs alleged that Microsoft abused monopoly power in its handling of operating system sales and hypervisor sales. The issue central to the case was whether Microsoft was allowed to bundle its flagship Hyper-V hypervisor software with its Microsoft Windows operating system.

Bundling them together is alleged to have been responsible for Microsoft’s victory in the hypervisor wars as every Windows user had a copy of Hyper-V. It was further alleged that this unfairly restricted the market for competing hypervisors (such as VMware Inc.) that were slow to download over a modem or had to be purchased at a store.

Underlying these disputes were questions over whether Microsoft altered or manipulated its application programming interfaces (APIs) to favor Hyper-V over third-party hypervisors, Microsoft’s conduct in forming restrictive licensing agreements with OEM computer manufacturers, and Microsoft’s intent in its course of conduct.

Microsoft stated that the merging of Microsoft Windows and Hyper-V was the result of innovation and competition, that the two were now the same product and were inextricably linked together and that consumers were now getting all the benefits of IE for free. Those who opposed Microsoft’s position countered that the hypervisor was still a distinct and separate product which did not need to be tied to the operating system, since a separate version of Hyper-V was available for Mac OS. They also asserted that IE was not really free because its development and marketing costs may have kept the price of Windows higher than it might otherwise have been. The case was tried before U.S. District Court Judge Thomas Penfield Jackson. The DOJ was initially represented by David Boies.

That was fun. Just a game, of course.

But it appears to me that by bundling Hyper-V with Windows Server 2008, Microsoft has the same advantage over VMware, Citrix and any other hypervisor provider that it had over Netscape Navigator in the 1990s.

This time around, Microsoft is probably safe from a lawsuit, though.

According to Wikipedia, “On November 2, 2001, the DOJ reached an agreement with Microsoft to settle the case. The proposed settlement required Microsoft to share its application programming interfaces with third-party companies. … However, the DOJ did not require Microsoft to change any of its code nor prevent Microsoft from tying other software with Windows in the future. … Nine states and the District of Columbia did not agree with the settlement, arguing that it did not go far enough to curb Microsoft’s anti-competitive business practices. On June 30, 2004, the U.S. appeals court unanimously approved the settlement with the Justice Department, rejecting objections from Massachusetts that the sanctions were inadequate.”

I’m not saying that what happened to Netscape will happen to VMware. In the virtualization market, VMware is in a strong position with a huge lead over Microsoft, and VMware’s products are far more mature and feature-rich. Hell, Microsoft doesn’t even offer live migration yet.
VMware Potential Tombstone

But some analysts predict that history will repeat itself.

I hope all the existing hypervisor vendors can co-exist. It gives users choice and keeps costs down, as we saw when both Citrix and VMware reduced their hypervisor prices to zero this year.

I’d like to hear your feedback on the virtualization industry and whether you think VMware can maintain its position as industry leader.

CiRBA analysis tool compares Hyper-V and VMware



Posted by: Bridget Botelho
Microsoft, Virtualization, VMware, Why choose server virtualization?, Microsoft Hyper-V, CiRBA

If you are thinking about Microsoft Hyper-V virtualization but aren’t sure how it will fare against VMware in your data center, a new tool from Toronto, Ontario-based CiRBA Inc. might help.

This week, CiRBA announced the availability of packaged analysis templates that compare Windows Server 2008 Hyper-V versus VMware-based virtualization.

Using CiRBA’s analysis, data centers can examine the suitability of each hypervisor for a given environment, see consolidation ratios, long-term management considerations and financial returns from each platform.

CiRBA’s analysis templates for Hyper-V and VMware-based virtualization are driven by specialized Rulesets for each platform in combination with utilization analysis.

The new comparative analysis templates for Hyper-V and VMware essentially provide a vendor-agnostic analysis, data, and organization-specific business and technical constraints to determine the best option for any given environment. Examples of comparison points between the two competitor products include:

*Per-guest resource limits: Hyper-V and VMware offer different per-guest maximum resource configurations, meaning the number of virtual CPUs, memory and network interfaces supported, which could impact compatibility.

*Memory over commit: Hyper-V and VMware differ in their ability to share memory between VMs, making efficiency gains through “over-commitment.” This differentiating factor can impact consolidation ratios and infrastructure design.

*Workload mobility: The two technologies differ in their support for the live migration of workloads between physical servers. Hyper-V doesn’t offer live migration yet, VMware does (VMotion).

CiRBA customers can access these new analysis features through CiRBA Central, a central repository of analysis rules that allows organizations to stay up to date on the latest best practices in data center optimization. CiRBA Powered Partners will also have access to these rules in order to help guide their clients through the selection of optimal technology for their environment.

For more information on CiRBA’s comparative analysis for Hyper-V versus VMware, contact the company.

BMC intros slew of virtualization management products



Posted by: Bridget Botelho
Product announcements, Microsoft, Virtualization, Servers, Virtual machine, Virtualization management, VMware, Virtualization security, Microsoft Hyper-V, Citrix XenServer, BMC, vKernel, Hyperic, Inc

Houston-based BMC Software introduced several new virtualization management products today, including nine new integrated offerings designed to eliminate the risk and operational expenses associated with management of virtualized data centers.

BMC’s new virtualization management products are fully integrated with virtualization products from Microsoft, Sun Microsystems, Inc. and VMware Inc. The new BMC software is based on an automated set of closed-loop change and configuration management (CLCCM) process workflows that reduce the latency, cost and risk associated with change management. All of the new offerings support both virtual and physical infrastructures.

The nine new offerings support goals for performance, compliance and enterprise visibility by addressing the challenges created by virtualization.

Some of the issues addressed include the following:

*Planning a virtualization/consolidation initiative: BMC Virtualization Capacity Management and Planning Service is a packaged services offering that helps customers accelerate their virtualization efforts.

*Simplifying management: BMC Performance Management does complete performance monitoring across virtual infrastructure and applications with enhanced VMware Infrastructure 3 and VMotion support.

*Ensuring availability: BMC Application Performance and Analytics helps IT actively manage service levels in virtual infrastructures.

*Performance: BMC Capacity Management replaces educated guesses with automatic assessment, prioritization of server workloads, and ongoing capacity monitoring. The result is high performance while reducing capital and operational expenses and maximizing server consolidation.

*Server sprawl: Virtualization allows new servers to be created very rapidly, leading to virtual machine (VM) sprawl. BMC Discovery Solution helps customers keep virtualized environments under control by keeping tabs on virtual servers. Support for VMware, Solaris 9/10 containers and zones, AIX LPARS as well as z/VM dependencies on mainframe (z/OS) mean that all types of virtual servers can be discovered and added to BMC Atrium CMDB.

*VM security: BMC BladeLogic Virtualization Module for Servers adds security and strengthens licensing and regulatory compliance. It includes automatic provisioning and configuration of the entire software stack, including virtual infrastructure, guest VMs and applications, and enforces security best practices, including built-in virtual server hardening rules.

*Compliance: BMC BladeLogic Operations Management Suite establishes automated, closed-loop change and configuration governance over entire virtualized environments. BMC’s policy-driven configuration control prohibits noncompliant servers from being deployed or existing beyond the next audit scan. Automated compliance and remediation capabilities detect and correct any compliance violations.

*Administration costs: BMC Run Book Automation Platform and BMC Run Book Automation VMware Adapter exploit BMC’s CLCCM workflows to automate routine change management tasks.

Of course, BMC isn’t the only game in town when it comes to virtual infrastructure management. There are a number of vendors offering management products for various purposes, including Portsmouth, N.H.-based vKernel and San Francisco-based Hyperic, Inc.

In addition, Austin, Texas-based Surgient announced today its Virtual Automation Platform 6.0, which is designed with physical provisioning and Microsoft Windows Server 2008 Hyper-V support to manage virtual resources and eliminate physical server and virtual machine (VM) sprawl.

In addition to third-party VM management products, virtualization providers offer their own; VMware sells a proprietary management and automation suite, as does Microsoft for Hyper-V.

News of the week: VMware’s ESX 3.5 bug causes VM failure



Posted by: Bridget Botelho
Microsoft, Virtualization, Virtual machine, VMware, Microsoft Hyper-V

This week, the biggest news item on SearchServerVirtualization.comVMwarewas the havoc caused by VMware Inc.’s ESX 3.5 update 2 bug, which kept virtual machines (VMs) from booting up and live migrating (VMotion) on Aug. 12.

Users posted their fury on IT forums like ARS Technica’s the Server Room. One user on the forum summed up the situation perfectly. “This was a very big deal, make no excuses for VMware. It certainly had potential to completely disrupt a lot of customers. … At most it should have disabled VMotion and other extras but not starting a VM.”

In the afternoon on Aug. 12, VMware issued an Express Patch on its Knowledgebase site and warned users not to install ESX 3.5 Update2 or ESXi 3.5 Update 2 if it has been downloaded from VMware’s website or elsewhere prior to Aug. 12, 2008.

VMware’s new CEO, Paul Martiz, issued an apology letter the day of the bug explaining the issue.

When the time clock in a server running ESX 3.5 or ESXi 3.5 Update 2 hits 12:00AM on August 12th, 2008, the released code causes the product license to expire. The problem has also occurred with a recent patch to ESX 3.5 or ESXi 3.5 Update 2. When an ESX or ESXi 3.5 server thinks its license has expired, the following can happen:

  • Virtual machines that are powered off cannot be turned on;
  • Virtual machines that have been suspended fail to leave suspend mode; and,
  • Virtual machines cannot be migrated using VMotion.

The issue was caused by a piece of code that was mistakenly left enabled for the final release of Update 2. This piece of code was left over from the pre-release versions of Update 2 and was designed to ensure that customers are running on the supported generally available version of Update 2.

… I am sure you’re wondering how this could happen. We failed in two areas:

  • Not disabling the code in the final release of Update 2; and
  • Not catching it in our quality assurance process.

We are doing everything in our power to make sure this doesn’t happen again. VMware prides itself on the quality and reliability of our products, and this incident has prompted a thorough self-examination of how we create and deliver products to our customers. We have kicked off a comprehensive, in-depth review of our QA and release processes, and will quickly make the needed changes.

I want to apologize for the disruption and difficulty this issue may have caused to our customers and our partners. Your confidence in VMware is extremely important to us, and we are committed to restoring that confidence fully and quickly.

It remains to be seen whether Maritz’ apology is enough to satisfy frustrated users. A major issue like this may prompt users to try other virtualization products. For instance, the day of the incident, some users were singing praises of Microsoft Hyper-V on technical forums.

Either way, having to deal with this issue after only a month in charge is really initiation by fire for Maritz.

And I imagine that VMware co-founder and ex-CEO Diane Greene, who was ousted by VMware’s board of directors July 8, might feel at least somewhat vindicated.
