Xen Outreachy application

[Linda <lindaj@jma3.com>]

Hi Lars,
     I am aware of it.  Thank you.  I've been having trouble with builds 
and git send-emails.  The code is written and minimally unit tested.  I 
would love to have it reviewed.
     I'm waiting on answers/suggestions from Julien and Wei, who have 
been very responsive.  They deserve gold stars for their patience with me.
     BTW, I hope you don't mind I changed the subject line, so the 
developers on the list understand the circumstances.

Thanks,

Linda Jacobson
