Hows the script to read from a csv file and create VM’s based on a template going. I’ve got as far as creating the VM’s from a csv file but struggling with creating them from a template.

I have read the storage-path-lo article on the VMware blog and found in an facinating process.

The one you are working is just the function Sven asked about, I am axious to see what’s the result of that.

I prefer the simple oneliner scripting thingies because they show the real power of powershell and are much easier to understand for people who are starting with scripting / powershell

What I like about powershell is the simplicity of the commands and the ease to create powerfull single line scripts, aka one-liners.

That’s easy as well but it took a little work:
first I put all the snapshots into a single variable with this command:
$snap = get-snapshot -vm * this variable can be used as input for the actual removal:
remove-snapshot -snapshot $snap.

you can combine the two commands on a single line:
$snap=get-snapshot -vm * ; remove-snapshot -snapshot $snap

on the otherhand I cannot emphasize the importace of being carefull with such powerfull commands !

that’s all

I created a couple of scripts, for example the HBA loadbalance script, see http://blogs.vmware.com/vipowershell/2008/07/storage-path-lo.html

Currently i am busy creating a script that read a .csv file, creates a VM based on a template. But it can also poweroff and remove a VM and redeploy it.

Also the script has the possibility to be put in a resourcepool or in the clusters default resourcepool.
Ask Matthijs about it, he is my current collegue at project we are working on right now.

how about this:
list al VM’s which has snapshots, then delete those snapshots.

That’s easy:
First you need to connect to a VI or ESX server with the Connect-VIServer (like Rob pointed out)commandlet

next you use the get-networkadapter commandlet en pipes the output to the set-networkadapter
the complete commandline will be:
Get-NetworkAdapter -VM * |set-networkadapter -connected $false

the otherone I will explain in a future article

Can you create a powershell script that disconnects the network interfaces in all virtual machines? This can be usefull in case of a virus-outbreak.

Another script that would be usefull is a script that reads out a CSV or TXT file (which contains certain parameters like VM-name, memory size, network, template to use) and then uses those parameters to deploy a new VM.

Thanx for the comment a typo can easily be made. In reply of your comment are there any automated tasks you would to have scripted or do you have by any means usefull scripts ?
