Note – 7-9-2015: Apparently, there were enough downloads of the presentation today that I’ve hit a Dropbox bandwidth limit. If you’re hitting this issue, please try downloading again tomorrow.

Update – 7-10-2015: It looks like Dropbox is still suspending access, so the virtualization session slides are also available via the links below:
