Creation of the virtual machine on a cluster via vmcreate.pl script

Hi,

I have checked few posts on this forum on how to create the virtual machine via vmcreate.pl, but the responses was not so clear to me...

These are the topics I have read:

Create VM instance on Cluster

How to set up the HostSystem Managed object

So, I would like to create a virtual machine on a Cluster, not on a specified host. Does the script vmcreate.pl would do the job ? Or I should modify it ?

From the topic => Create VM instance on Cluster    I didn't quite get, what should I modify ...

This is what I do:

vmcreate.pl --server "ESX NAME" --username "LOGIN" --password "PASS" --filename vmcreate.xml --schema vmcreate.xsd

Result:

Error creating VM 'myTestMachine':

SOAP Fault:

-----------

Fault string: InvalidArgument

Fault detail: InvalidArgument

Here are the XML file values:

                <Name>myTestMachine</Name>

                <Host>blabla</Host>

                <Datacenter>blabla</Datacenter>

                <Guest-Id>Linioch</Guest-Id>

                <Datastore>blabla</Datastore>

                <Disksize>2048</Disksize>

                <Memory>256</Memory>

                <Number-of-Processor>1</Number-of-Processor>

                <Nic-Network></Nic-Network>

                <Nic-Poweron>1</Nic-Poweron>

The values are correct cause I have checked them via other perl scripts.

Thank You in advance for Your help

Michal
