Features of KVM
KVM (Kernel-based Virtual Machine) is a type 1 hypervisor that allows multiple virtual machines (VMs) to run on a single physical server. A few key features of the KVM hypervisor in VPS (Virtual Private Server) hosting that make it a reliable hosting technology are:
Full virtualization solution
KVM provides full virtualization, which means that each virtual machine is completely isolated from other VMs and the host system and has its virtual hardware, including CPU, memory, storage, and network interfaces.
Linux-Based Technology
KVM is a Linux-based virtualization technology that is integrated into the Linux kernel. This means that it can leverage the stability, security, and performance of the Linux operating system.
Hardware Virtualization Support
KVM uses hardware virtualization and hardware support from the CPU to provide efficient virtualization. Thus allowing VMs to run at near-native performance levels.
Live Migration
KVM supports live migration, allowing VMs to be moved from one host to another without downtime.
Snapshotting
KVM allows for snapshotting virtual machines, allowing administrators to create a point-in-time copy of a virtual machine. This can be useful for backup and recovery, testing and development, or creating sandbox environments.
Resource Allocation
KVM allows administrators to allocate CPU, memory, and disk space resources to servers. This allows for efficient use of hardware resources and ensures each VM has the resources it needs to operate effectively.
