+This is a general libvirt/virtualization/libguestfs talk given at the
+2013 CentOS Dojo in Aldershot.
+
+http://wiki.centos.org/Events/Dojo/Aldershot2013
+
+The whole talk is designed to take around 15-20 minutes, with an open
+Q&A about virtualization at the end lasting another 20 minutes.
+
+To run the talk you'll need Tech Talk PSE >= 1.1.0. If you don't have
+Tech Talk then just open up the HTML slides in a web browser.
+
+To start the talk, use `./run'.

+
+--- If there are no immediate questions, then:
+
+* How many people are using virtualization at all?
+
+* How many people have virtualized some of their servers?
+
+* How many people are using Amazon EC2 or another public cloud?
+
+* How many people are running a public VPS or public cloud?
+
+* How many people are running a private cloud or cloud-like service
+ within their company?
+
+* How many people are running VMware?
+
+* How many people are running Xen?
+
+* How many people are running KVM?
+
+* What would stop you from moving away from VMware?
+
+* What would stop you from moving to libvirt?
+
+* What would stop you from moving to Open Stack or oVirt?
