KVM Linux Virtualisation Jobs
KVM (Kernel-based Virtual Machine) is the native hypervisor built into the Linux kernel, forming the foundation of major cloud platforms including AWS EC2, Google Compute Engine, and OpenStack. KVM engineers work with libvirt, QEMU, and virtualisation management tooling to build and operate private clouds, on-premise virtualisation platforms, and development infrastructure.
Frequently Asked Questions
-
KVM is a Type 1 hypervisor built into the Linux kernel since version 2.6.20. It turns Linux into a bare-metal hypervisor using hardware virtualisation extensions (Intel VT-x, AMD-V). Unlike VMware ESXi or Hyper-V which are standalone hypervisors, KVM runs as part of the Linux kernel, making it the foundation for OpenStack, oVirt, and public cloud VM hosting.
-
libvirt is the standard management API and daemon for KVM, providing a consistent interface for VM lifecycle management across different hypervisors. virsh is the command-line tool, while Virtual Machine Manager (virt-manager) provides a GUI. QEMU provides the device emulation layer that KVM relies on. oVirt and OpenStack use libvirt as their KVM management layer.
-
Yes. AWS EC2 uses a customised KVM-based hypervisor called Nitro. Google Compute Engine runs on KVM. OpenStack, the most widely deployed private cloud platform, uses KVM as its default hypervisor. Engineers working on cloud infrastructure, data centre virtualisation, or private OpenStack deployments will routinely work with KVM.
-
KVM roles require deep Linux kernel knowledge including CPU and memory management, NUMA architecture, and storage I/O paths. Experience with libvirt, QEMU, and network bridge configuration using Linux bridges or Open vSwitch is essential. Storage knowledge covering LVM, Ceph, and NFS for backing VM disk images is expected in platform engineering roles.
