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.
