Topics to be covered in the talk include

• Capabilities for mutual exclusion / locking of guest disk images
• Fine grained access control against individual operations, users and objects in the API
• The sVirt mandatory access control framework
• Auditing and structured logging via the systemd journal
• Integration with systemd and cgroups for resource management

In the 8+ years since it has been founded, the libvirt project has grown to become the leading open source API for the management of virtualization hosts, with a strong focus on supporting the open source virtualization & container technologies, KVM, QEMU, Xen and LXC. Many people working in the open source virtualization management space already have an understanding of the core features and architecture of libvirt. This talk will thus focus on a selection of recently developed features and of some of the other important, but less well known, features of libvirt.

The talk will be targeted at virtualization application developers using libvirt, with a bias towards those using KVM or LXC. At the end of the talk the audience will better understand how to take advantage of libvirt for their development needs.

Entangle is an open source project that provides a Linux desktop application for “tethered shooting”. It uses the ligphoto2 library to trigger the camera shutter, preview shots via the camera's "live view" capability, download captured images and access all the live camera settings. It is useful for a variety of use cases including studio model shoots, macro still life, stop motion animation shoots, astro-photography and more.

The talk will be targeted at Linux users & developers who are photographers interested in any of the aforementioned use cases.

The talk will provide an overview of the important capabilities of the program and, if all goes to plan, a live demonstration of the application in use.

The aim is to demonstrate the potential of the application to users who are not already aware of its existence, and attract open source developers to contribute to the project.

The libvirt library provides a hypervisor agnostic API for interacting with & managing virtualization hosts. Traditional uses of virtualization have focused on running entire operating systems in virtual machines or containers. The libvirt-sandbox library builds on libvirt, LXC & KVM, providing an API which facilitates the use of virtualization as a tool for building secure application sandboxes, without the additional burden of maintaining additional OS installations.
