In that case I am sure there is going to be enough time for everything.

The topic and the abstract follow, let me know if you would like me to
make any changes. 



Topic
Xen support in the Linux kernel: upstreaming efforts and new developments

Abstract
Xen reuses many externals Open Source projects, Qemu and Linux in
particular.
During the first years of existence Xen accumulated a large amount of
changes to these external projects but then struggled to upstream them.
In the last couple of years the Xen Community has been trying to remove
the dependencies on downstream modifications and establish better
relationships with other Open Source Communities.
What is the current status of Xen in relation with other Free Software
projects?
At the same time Xen development proceeded at a fast pace and several
new features were introduced; this talk will go through one in
particular: PV on HVM support in the Linux kernel.
Traditionally Linux has always run on Xen either as a pure PV guest or
as a virtualization unaware guest in an HVM domain.
Under the name of "PV on HVM", a series of works has been done
to make Linux aware that is running on Xen and enable as many PV
interfaces as possible even when running in an HVM container.
