I got this email a couple of hours ago:

Dear Boris Quiroz,

thank you for submitting a talk proposal for LinuxTag. There is good
news as your paper #15259:

Xen as an IT plataform in Latam enterprises

has been accepted for the conference. You may receive several copies
of this message if you are scheduled to more than a single
presentation. All registered speakers of a presentation should receive
an individual copy of this notification.

Great. I’m going to Berlin to talk about Xen and I’ll take a couple of bottles of Pisco with me. I really like to be geek =)
