[Users] Cloud-init for Windows

Tue Apr 8 11:06:13 UTC 2014

Hi,

When i tried the above solution, i face few challanges:

1. I'm able to add VMPayload via CURL, but not via JavaSDK.
2. When i add VMPayload via CURL, sysprep fails with this message "windows
could not parse or process the unattend answer file [a:\sysprep.inf] for
pass [oobeSystem]. A component or setting specified in the answer file does
not exist."
