Igalia has a team specialized in hypervisors, system virtualization and cloud technologies. Our engineers write, maintain, and port drivers and provide solutions and development services using the QEMU/KVM hypervisor as well as the Ceph storage system.

QEMU

Igalia has many years of experience with the QEMU project and is one of its most active corporate contributors. We have worked on QEMU’s block layer by adding features and fixing problems for cloud scenarios, and have also worked on the emulation of new hardware.

We have made many upstream contributions to the qcow2 file format and I/O layer. On QEMU’s native qcow2 file format and driver, we improved performance and reduced the amount of host RAM required by the driver. Igalia has also implemented group-based I/O limits and bursts for virtual disk images that can be configured in a way similar to Amazon’s Elastic Block Store. We extended I/O accounting, allowing the user to obtain better statistics of a VM’s disk usage. Apart from that, we have also worked in advanced snapshot creation and emulation of new hardware boards and a new bus (IndustryPack).

Ceph

Igalia is also one of the companies contributing code upstream to the Ceph project and other cloud technologies.

We have contributed to the RADOS gateway with the AWS4 S3 authentication algorithm and the AWS S3 requester pays bucket, among other features. Additionally, Igalia has also worked on the integration of Apache Libcloud and Ansible with Ceph.

Beyond designing, developing and upstreaming new code features in the upcoming Ceph releases, we also work on bugfixing tasks, backporting, interoperability issues and daily code maintenance together with the required QA and testing efforts.
