Labmanager vmware8/10/2023 These commands are executed as part of the GUIRunOnce process when the machine first boots. Build out our list of GUIRunOnce actions. ![]() Get a machine template from the library.This is an all too easy assumption on our part - but our example is simple. Grab the first logical network associated with that cloud for our use.Get the private cloud the machine belongs to using Get-SCCloud.Our next step is to gather up the required information needed to provision our new machines. Provision-Environment Cloud="MyPrivateCloud" VMMServerName="vmmserver" AnswerFile="\\host\Library\Custom Configurations\Unattend.xml" DeleteExisting="True" WaitBetween="120"> This format is flexible and easy to modify and/or extend. (This functionality can be overridden using Persist=”true” on the machine element or by setting DeleteExisting=”false” on the Provision-Environment element).Īs part of each element we provide some additional metadata that will be used during this process such as the name of the machine, size of the drives, etc… A sample XML configuration is shown below. As we do this, we look for any existing machines by that name and remove those. In the above function, we actually loop through a series of XML elements where each element represents a machine. A copy of the VMCreateLibrary that we use is also available here. The PowerShell function used to provision a VM environment. This function takes a lot of the built-in PowerShell functions exposed by VMM (kudos to Microsoft for this approach) and just wraps it with some additional logic to put all the pieces together for you. I’m including a copy of the function we use called Provision-Environment. The spirit of these scripts could be translated to something like VMWare, or you could use VMM to manage a VMWare infrastructure if you really wanted. Since we use Virtual Machine Manager (VMM), the contents of these scripts are specific to that product. Executions of other steps obviously follow, but this post is primarily concerned with standing up that environment. In reality the process of removing and creating VMs is treated as just one “step” in our build-out process. We use the same XML-driven framework to build out our machines. In a way, this allows us to test both pieces at the same time.Īt this point I should throw in the disclaimer that this blog post builds on one written by my colleague David Baber: Driving PowerShell With XML. However, we wanted something that could not only exercise our code base, but also our scripts that we use for building our environment. This may sound like overkill and I’ve seen other approaches that use snapshots and revert each night…and I think that’s great. We don’t use snapshots we actually delete and provision a series of VMs. Today I want to talk about a process we created for building out machines using Virtual Machine Manager (VMM) as part of our daily build process within Team Foundation Server (TFS).Īs part of our nightly build process, we actually recreate the entire environment from scratch.
