Subject RE: [Proposal] Userdata Support for Hyper-V with KVP Data Exchange
Date Fri, 13 Sep 2013 17:25:47 GMT
Hi Darren, 

To bring up the system vm's on the hyperv host we need to pass the boot args from host to
the systemvm's.
To pass the data from hyperv host to systemvm guest we need this method.

Why does Hyper-V need something specific?  Is userdata really hypervisor specific?  I though
we just put the userdata on the VR?
