Posted by: Rick Vanover

I recently upgraded to ESX 3.5 on a test system, and had an issue that was really stressing me out. The issue was that each time I would perform the "Reconfigure for HA" task, I had errors causing the task to fail and the new ESX host sits there with a red triangle like a car broken down on the...

Monitor the Virtual Infrastructure Database for authentication attempts

Because VMware ESX and Virtual Center (VC) have great magnitude in the datacenter, I determined it would be a good idea to have an audit trail of authentication attempts in to the Virtual Infrastructure Client and SSH on the host. In my recently upgraded VC 2.5 environment, I made a quick trip to...

Rick Vanover, VI3, Virtualization, VMware ESX

When planning your next VMware ESX server installation that will be managed by VirtualCenter 2.5, make sure you provision for redundant networking for the ESX service console port. VirtualCenter 2.5 gives you a warning if you only have one interface assigned as the role of service console port, but...

Use disconnected network adapters for build and stage: Save yourself



Posted by: Rick Vanover
Networking, Rick Vanover, VI3, Virtualization, VMware ESX

In VMware ESX, you can configure a guest operating system to have its network adapter disconnected at power on. This is critically important for a phase of a physical to virtual (P2V) migration where the system is migrated yet there are some offline tasks to be done. This can also be during a build...

I've written several articles on SearchServerVirtualization about the VI3 SDK and how to make the most of it with .NET. There is an as-yet unpublished article on how to implement Layer-2 network security with .NET using a program I wrote called gnicmod. Consider it part 4 in my series of leveraging...

The Perl script, vmreconfig.pl, is designed to reconfigure a virtual machine (VM). You can read more about it here. The tool can be used to make changes to the state of the VM. For example, you...

Generating the XML necessary to create VMs with the VI Perl Toolkit



Posted by: Akutz
Andrew Kutz, VI3, Virtualization, VMware ESX

It is a pain in the rear to generate XML on the fly. There just is not a fun way of doing it. Unfortunately this is what is required when creating, cloning, and altering VMs with the VI Perl toolkit. I went ahead and creating a very simple Perl script that will take HTML GET variables from the...

Using Hyperic to Manage VMware Environments, part 1



Posted by: Joe Foran
DataCenter, Joseph Foran, Virtualization, VMware ESX

At the risk of sounding like a commercial, Hyperic HQ is my leading-choice for agent-based systems management tools to handle both VMware and non-VMware systems. Personally I tend to prefer non-agent-based systems, but the Hyperic tools work,...
