Kernel-based Virtual Machine (KVM) is a virtualization infrastructure for the Linux. It converts the Linux kernel into a bare metal hypervisor and it leverages the advanced features of Intel VT-X and AMD-V x86 hardware, thus delivering unsurpassed performance levels. Using KVM, one can run multiple virtual machines running unmodified Linux or Windows images.

Why KVM Virtualization For your Business


KVM boasts of security-enhanced Linux (SELinux) and secure virtualization (sVirt) for enhanced VM security and isolation. SELinux establishes security boundaries among VMs. Whereas sVirt extends SELinux’s capabilities further more.


KVM Support different storage such as local disks and network-attached storage (NAS). Multipath I/O can be used to improve storage functionality. KVM also supports shared file systems and disk images such as thin provisioning, allocating storage on demand rather than all up front.

Memory Management

KVM inherits the memory management features of Linux, with non-uniform memory access.The memory of a VM can be swapped, backed by large volumes for better performance, and shared or backed by a disk file.

Live Migration & Security

KVM has the ability to move a running VM between physical hosts with no downtimes. The VM remains powered on, network connections remain active, and applications continue to run while the VM is relocated. KVM also saves VM's current state so that it can be later restored instantly.


KVM support scaling to match on-demand load if the number of guest machines and requests increases. KVM allows the most demanding application workloads to be virtualized and is the basis for many enterprise virtualization.

Resource Control

KVM includes the completely fair scheduler, control groups, network name spaces, and real-time extensions that allows fine-grained control of the resources allocated to a Linux process and guarantees a quality of service for a particular process.
