[one-users] windows vm context

[Paul Batchelor]

One alternative approach I experimented with was casting the template XML directly to a powershell object - e.g.

You include the following line in your template to include the base-64 encoded XML

  TMPL="$TEMPLATE"

Then in the context PS script you can do the following once you have read the base64 encoded XML into a variable:

       [xml]$vmtemplate = [System.Text.Encoding]::Ascii.GetString([System.Convert]::FromBase64String( $base64template ))

You can then directly reference the VM template properties as PS objects -e.g.

       $mydatastore    = $vmtemplate.VM.TEMPLATE.DISK.DATASTORE.'#cdata-section'
       $myinvocationid = $vmtemplate.VM.ID
       $ownername      = $vmtemplate.VM.UNAME


This means you don't need to worry about what the quoting is for the template parameters except for the initial load of the base64 encoded XML.

Cheers

Hi Hans,

please keep OpenNebula related mails on the list.

We run Windows 7 and 8 professional as VM managed by OpenNebula.
On the OpenNebula wiki (http://wiki.opennebula.org/) you will find a section called “Images and Stores”.
Within that section you will find a link to a complete documentation:
http://wiki.ieeta.pt/wiki/index.php/OpenNebula#Using_Windows_Images_for_new_Virtual_Machines

We only did one modification to the one-context.ps1 script which allows us to read data properly:

function getContext($file) {
       $context = @{}
       switch -regex -file $file {
               '(.+)="(.+)"’ {            ###### <——— other regexp
                       $name,$value = $matches[1..2]
                       $context[$name] = $value
               }
       }
       return $context
}

hth,

Martin
