Customize winodws vm template


Please tell me how to do the following:

I have template with pre-installed windows. I generalize it use command: sysprep /generalize /shutdown /oobe.
Now I need push unattend.xml file (create via system image manager) and some parameters, that will change users in provision dialog.
I have RHEV and Vmware provider.

Is there a way, without PXE server?

Thanks for help,

@blomquisg can you review this question from @ban and forward to a SME if necessary.
