[one-users] missing cdrom device - no context!

Mon Jul 19 12:27:54 PDT 2010

Hi Dan,

Sorry for the delay, kind of hectic this days.

It seems at first sight that you are not including in the VM template the
CONTEXT section [1], which will explain why you are not getting the block
device attached to your VM.

Best regards,

-Tino
