CloudFORMS lacks currently the ability to create a template from an existing VM, here is the method to enable this function from a custom button.
First you need a dialog to collect from the new user the name of the template, so create a dialog of your liking, including at least;
Textbox – Name = dialog_name
Next is to create the custom button, so create a new group to take the button, and in it a button that calls your new dialog you created in the previous step, along with a request instance called create_template. Don’t forget you are creating the button in the VM group.
Now for the automate bits,
- Create an instance in /system/request called create_template.
- Edit your new instance and wire it to /Sample/Methods/create_template
- Create an instance in /Sample/Methods called create_template.
- Create an method in /Sample/Methods called create_template.
- add the following code to your new method;
</pre>
#
# Automate Method
#
$evm.log("info", "Automate Method Started")
#
# Method Code Goes here
#
#!/usr/bin/ruby
require 'rubygems'
require 'rest_client'
vm = $evm.root['vm']
ext_management_system = vm.ext_management_system
$evm.log("info", "VM Name - #{vm.name}")
$evm.log("info", "VM UID - #{vm.uid_ems}")
$evm.log("info", "RHEVM Name - #{ext_management_system.name}")
$dialog_name = ' '
$evm.root.attributes.sort.each { |k, v|
$evm.log("info","#{k}---#{v}")
if "#{k}" == "dialog_name"
$dialog_name = "#{v}"
$evm.log("info", "Found #{$dialog_name}")
end
}
rhevm = "https://#{ext_management_system.ipaddress}/api/templates"
rhevadmin = 'admin@internal'
rhevadminpass = 'monster'
resource = RestClient::Resource.new(rhevm, :user => rhevadmin, :password => rhevadminpass)
createTemplate = resource.post "<template><name>#{$dialog_name}</name><vm id="#{vm.uid_ems}"></vm></template>", :content_type => 'application/xml', :accept => 'application/xml'
$evm.log("info", "Result - #{createTemplate}")
#
#
#
$evm.log("info", "Automate Method Ended")
exit MIQ_OK
So to test, select a VM and execute your button, in the log you should see something like;

and in RHEV-M you should see your new template…
