There are two critical steps to complete before you get started.
- Make sure you configure PowerShell to allow remote script execution. set-executionpolicyremotesigned
- Connect to your vCenter server or to an individual ESX/ESXi host. Connect-VIServer -Server 192.168.200.1 -Protocol https -User root -Password passwordgoeshere
Gather additional details about a running virtual machine isn’t an arduous process using PowerShell, but there are some ways that you can make your life easier as you move forward. In order to the process a bit easier, we’ll actually assign the results of the get-vm command, which we discussed in part 1 of this series, to a variable that we can then manipulate to get the information we want. By learning how to, for example, list the hard disks associated with a virtual machine, you’ll be able to get better statistics down the line.
To assign all of a single virtual machine’s properties to a variable, use a syntax like the following:
$v = get-vm win7-usb
This will assign all of the results from the get-vm win7-usb command to the newly created variable named $v. Ideally, in the real world, you’ll use more descriptive variable names, but to keep things a little clearer for demonstration purposes, I’m using shorter names.
This is a “point in time” snapshot of how the virtual machine looked at the time its information was committed to the variable named $v. If you make configuration changes later on, you need to run the same command again to update the variable’s contents.
Now, let’s get a little bit of information about what’s been assigned to this variable. In order to do so, let’s start with something basic. Simply execute the command $v with no parameters. You will get something similar to the result shown in the figure below.
Because we’ve assigned the results of the get-vm command to the variable named $v, you see the VM stats by executing just $v.
Now, suppose you want to see the network adapters assigned to this virtual machine. “NetworkAdapters” is a property for the newly created $v variable by virtue of the fact that we’ve assigned VM configuration information to it.
To get the properties of the network adapters in the virtual machine, execute the command $v.NetworkAdapters.
There are a lot of other properties that you can get from a virtual machine, too, including:
