Score with Virtualization

February 24, 2009

We just got back from the Citrix virtualization seminar in Washington D.C. The seminar was very informative with live demos of their products. They pretty much covered all their virtualization products and how they work together: XenApp (application virtualization), XenDesktop (desktop virtualization), and XenServer (server virtualization). They also had three of their customers come in to share their experiences with Citrix virtualization technologies.

Now for the free stuff. Attendees received a small bag (man ...

How to change from ACPI Multiprocessor HAL back to ACPI Uniprocessor HAL in Windows 2003

January 9, 2009
Warning: Changing the number of virtual processors after the guest OS is installed may make your virtual machine unstable.

You’ve probably seen this message before while working with VMware, especially if you’ve done physical to virtual migrations.

As a best practice, it is recommended to always start with only 1 vCPU when creating virtual machines and only increase the number of vCPUs if you think it’s necessary and if the virtual machine ...

Converting Physical Citrix Server to VMware Using VMware Converter

We also use RSA SecurID for authentication and it still works after the conversion with no changes made to the RSA Authentication Manager or RSA ACE Agent (using the same IP address after the conversion of ...

Converting Microsoft Virtual Server 2005 Virtual Machines to VMware

September 14, 2008

We just converted 3 of our virtual machines running on Virtual Server 2005 R2 to VMware ESXi yesterday and it went pretty smoothly with just a couple of minor issues.

The first issue is the mouse cursor not working in VMware console after installing the VMware tools. The fix is just a simple registry edit:

  1. Open Registry Editor (regedit)
  2. Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E96F-E325-11CE-BFC1-08002BE10318}
  3. Double-click on UpperFilters and delete msvmmouf.
  4. Reboot ...

VMware ESXi First Impressions

September 3, 2008

I finally got a chance to try this out yesterday on a Dell PowerEdge 6600 server that we use for testing at work. I’ve been testing it pretty much most of yesterday and today and I have to say that I’m very impressed with it so far.

Installation was very easy:  download and burn the ISO image, boot from it, follow the installation instructions on the screen (which is pretty much next ...
