VMware Solutions Drastically Lower Operational Costs

PALO ALTO, Calif., December 21, 2009 — VMware, Inc. (NYSE: VMW), the global leader in virtualization solutions from the desktop through the datacenter and to the cloud, today announced independent research convincingly proves that VMware customers are drastically lowering operational expenditures (OpEx) with VMware solutions. VMware vSphere™ and the VMware vCenter™ Product Family lower the day-to-day costs of running IT, enabling IT resources and budgets to be shifted from tactical maintenance to strategic projects that can better create value for the business. “Reducing OpEx with Virtualization and Virtual Systems Management,” a whitepaper prepared by ENTERPRISE MANAGEMENT ASSOCIATES® (EMA™) for VMware, quantifies how customers have been able to reduce service failures, improve staff efficiency, speed up service deployment and reduce facility operation costs using VMware solutions.
The whitepaper (available from this page), which includes EMA research and VMware customer case studies, documents how VMware virtualization enables:

  • Reduction of Service Failures – fixing problems up to 24 times faster, eliminating up to 43 hours of downtime a year, improving uptime to as high as 99.999 percent, to reduce the impact, frequency, duration, and cost of service issues, troubleshooting, out-of-hours support, and productivity loss
  • Improved Staff Efficiency – increasing administrator efficiency by an average of 10 percent, and as much as 270 percent, by allowing a single administrator to manage up to 1,800 servers, reducing annual management costs by up to $1,000 per server
  • Faster Service Deployment – allowing new systems to be deployed up to 240 times faster, and new applications up to 96 times faster, saving almost $2,000 in wage costs alone per deployment, while reducing downtime, and improving time-to-market for new products and services
  • Reduced Facility Operation Costs – allowing approximately half of all organizations studied to reduce both floor space/rent costs, and power consumption, the latter by an average of 16 percent, or around $700,000 per year for a 5 megawatt datacenter

Annoying VM confirmations in VMware Infrastructure 2.5

I really like managing VMware ESX servers through VMware Infrastructure Client (using 2.5 version at the moment), but there's one little thing which really annoys me: most of VM-specific confirmations are asked with dialogue windows which don't mention the name of the VM they apply to.

For example, if I right-click the VM and decide to reset it, instead of getting something like "You're about to reset the HOSTNAME.DOMAINNAME.COM virtual machine. Are you sure?", I only see this:

Annoying Reset Confirmation

Annoying Reset Confirmation

I wonder if it's really hard to make these dialogs to be VM specific?

5 Great Articles Comparing VMware ESX to ESXi

Seems like the exact list of differences between VMware ESX and ESXi has been a very popular question lately. If you're interested in all the details, I've got some great links to share:

  • What is VMware ESX server 3i (ESXi)
  • VMware ESX and ESXi comparison – VMware KB article
  • Networking differences between ESX and ESXi – yet another VMware KB document

How To Change Lost Password on Your ESX Server

Doing a few experiments with VMware ESX 3.5 today, I've made a typo (twice!) when setting up a password for one of the systems, and this resulted in me locking myself out of ESX server upon the completion of its install.

Luckily, there's a rather easy way to change the forgotten password to something new, and I thought I'll explain how it can be done.

VMware Server 2.0 beta 2

VMware Server 2.0

Last Friday saw the long-awaited release of VMware Server 2.0 beta 2, Build 84186.

New features in VMware Server 2.0 beta 2

VMware website highlights the following new features of this VMware Server 2.0 release:

  • Updated VMware Infrastructure (VI) Web Access management interface: With the faster performance, improved stability and broader range of configuration options, the VI Web Access management interface provides a simple, flexible, intuitive and productive management experience. In addition, embedded help files are context sensitive based on the task being performed.
  • Independent virtual machine console: With the new VMware Remote Console, you can access your virtual machine consoles independent of the VI Web Access management interface plus resize the virtual machine console windows as needed.
  • Support for USB 2.0 devices: Transfer data at faster data rates from USB 2.0 devices.
  • Multi-tiered permissions: Configure different levels of permissions to access virtual machines in different ways, including browsing, interacting, configuring and administering virtual machines.
  • New hardware editors: Edit and add devices such as USB 2.0 devices and legacy devices such as floppy drives, serial and parallel ports.
  • Automatically start your virtual machines: Select which virtual machines that you want to automatically start when VMware Server starts. In addition, there is also an option to boot the virtual machine directly into the BIOS Setup Screen.
  • Link to Virtual Appliance Marketplace: Access thousands of pre-built, pre-configured, ready-to-run enterprise applications packaged with an operating system inside a virtual machine. This speeds up time to value and simplifies software development, distribution, and management.

Failed to allocate page for guest RAM error in Linux VMware Workstation

I've been spending increasingly more time researching topics for Unix Tutorial on one of my desktops. Ubuntu has replaced the Windows Vista I had and so far I quite like the experiment. Out of the box, all of the hardware was properly supported and even the NTFS partitions left from Vista install are easily available.

One of the first things I've decided to install was the trial version of the latest VMware Workstation: 6.0.3 build-80004. And although it installed without a problem, when I tried to run one of the previously created virtual machines, I got the following error:

VMware Workstation unrecoverable error: (vcpu-0)
Failed to allocate page for guest RAM!

As it turned out after a quick investigation, that was a result of running a VM from a NTFS partition, because its default mounting settings don't have the exec option.

Since you shouldn't be running anything critical through an NTFS driver anyway, I simply moved the VM onto one of the ext3 partitions and, sure enough, it fixed the guest RAM allocation error.

Update: if your scenario prevents you from moving a VM to a native partition, use the following option:

mainmem.UseNamedFile = "FALSE"

You should add it to the vmx file of your VM. Thanks for the tip, benito!

Critical security vulnerabilities fixed in VMware's hosted products

Many of you have probably heard about the recent Core Security findings which resulted in a security advisory CORE-2007-0930, Path Traversal vulnerability in VMware's shared folders implementation:

A vulnerability was found in VMware's shared folders mechanism that grants users of a Guest system read and write access to any portion of the Host's file system including the system folder and other security-sensitive files. Exploitation of these vulnerability allows attackers to break out of an isolated Guest system to compromise the underlying Host system that controls it.

Successful exploitation requires that the Shared Folder's feature to be enabled which is the default on VMware products that have the feature AND at least one folder of the Host system is configured for sharing.
