Virtualization and Cloud
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.
KVM (Kernel Virtual Machine) is a full virtualization solution for Linux. It consists of a loadable kernel module that provides the core virtualization infrastructure.
QEMU is an open source machine emulator and virtualizer. When used as a virtualizer, QEMU achieves near native performance by executing the guest code directly on the host CPU. When using KVM, QEMU can virtualize x86, server and embedded PowerPC, S390, 32-bit and 64-bit ARM, etc.
CEPH is a unified, distributed storage system designed to run applications with different storage interface needs and to manage vast amounts of data. Its Reliable Autonomic Distributed Object Store (RADOS) provides applications with object, block, and file system storage in a single unified storage cluster—making Ceph flexible, highly reliable and easy to manage.
Igalia has a team of engineers specialized in the cloud, storage and virtualization technologies who offer consultancy in the following areas:
- New Linux-based solutions and virtualization technologies development.
- Integration and customization of existing solutions.
- Porting and maintainance of drivers.
- QEMU / KVM: Hardware emulation and virtualization.
- New feature developments in QEMU / KVM and CEPH.
- Upstream development and maintenance.
We are long time developers with expertise in the Linux software stack, Kernel, CEPH and the QEMU / KVM hypervisor, making Igalia the perfect partner for your Linux-based hardware products.
I was in Prague last month for the 2017 edition of the KVM Forum. There I gave a talk about some of the work that I’ve been doing this year to improve the qcow2 file format used by QEMU for storing disk images. The focus of my work is to make qcow2...
This week I will be attending LibreCon 2017, one of the largest international events on open source technologies. It will be held on 19 and 20 October in Santiago de Compostela (Spain). This year’s theme is the application of open source technologies...
Some days ago Matt committed the great Radek's effort to have a more coherent and structured scaffolding in the Ceph RGW auth subsystem supporting the differences among the available auth algorithms. As part of this effort and patchset related to the...
When choosing a disk image format for your virtual machine one of the factors to take into considerations is its I/O performance. In this post I’ll talk a bit about the internals of qcow2 and about one of the aspects that can affect its performance...
Some fellows are using the Minio Client (mc) as their primary client-side tool to work with S3 cloud storage and filesystems. As you may know, mc works with the AWS v4 signature API and it provides a modern alternative under the Apache 2.0 License to UNIX...
