Under the Hood with Nova, Libvirt, and KVM (Part Two)

The October OpenStack L.A. meetup is on! And, for those of you who won't be able to make it to the OpenStack Summit in Paris, we have a real treat in store for you. Rafi Khardalian, Metacloud's CTO, has offered to give the presentation he'll be giving at the Summit to our group. So, mark your calendars and make plans to be here!

Presentation Abstract:

The Libvirt driver for Nova is one of the most comprehensive implementations across all supported hypervisors. It is quite common for new functionality to be added Libvirt before other drivers. During Part One (watch on Youtube (http://bit.ly/1tUZocH)), Rafi began to scratch the surface of this topic, and now it's time to get into the weeds.

During this session, Rafi will dive into more detail about Nova, Libvirt and QEMU:

• Commonly overlooked configuration considerations for Libvirt/QEMU.

• Which areas of the Nova Libvirt driver are most brittle and why?

• What happens when operations fail of complete impartially? How can we recover?

• Libvirt's interface into QEMU s Monitor Protocol (QMP).

• Live migration, block migration, migrate and suspend: What are the differences and how do they work? What parts is Nova handling, versus Libvirt and QEMU?

• Understand Libvirt's XML-based instance definitions.

If you missed Rafi's talk at the Atlanta Summit and are planning to attend Part Two, we encourage watching the video (watch on Youtube (http://bit.ly/1tUZocH)). He'll be picking up right where he left off.
