Subject: [PATCH] qemu: domain: Store data for 'secret' object representing
http cookies
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The http cookies can have potentially sensitive values and thus should
not be leaked into the command line. This means that we'll need to
instantiate a 'secret' object in qemu to pass the value encrypted.
This patch adds infrastructure for storing of the alias in the status
XML.
