KVM Forum 2017 BOF

Introduction

We will reserve some time for people to get together and discuss strategic decisions as well as other topics that are best solved within smaller groups. This time can also be used for hands-on hacking sessions.

If you are interested in organizing such a group time event, please add it to the list before KVM Forum, so people have time to organize which one they will attend.

Adding links to this wiki is restricted. If you have problems adding your BoF, please send it to the program committee at kvm-forum-2017-pc@redhat.com.
