![]() ![]() ![]() ![]() Although QEMU can work independently and emulate all virtual machine resources, this solution is very slow because entire emulation is done via software. QEMU – is a type 2 hypervisor (runs on the host operating system) and is used to support hardware virtualization.So it's no surprise that it only supports Linux as a host operating system. As the name suggests, KVM is based on the Linux kernel. Another advantage of KVM is access to source code and flexibility in integration with any software. It works as if the virtual machine operating system was operating directly on the host machine. KVM runs applications at a faster speed than other commercial hypervisors. KVM (Kernel-based Virtual Machine) – is an open source virtualization technology that turns the Linux kernel into type 1 hypervisor (works directly at the hardware level).Hypervisor provides guests with a virtual operating platform, allowing multiple operating systems to share virtualized resources on the same host. The computer running the hypervisor is called a host, and each virtual machine on the host is called a guest. Hypervisor – is a combination of software and hardware that creates, executes and manages virtual machines.Let's begin by explaining some basic virtualization-related notions based on the title set of components: Therefore, today we are going to take a closer look at KVM, QEMU, libvirt and virt-manager. Virtualization enables more effective use of existing hardware resources, generates large savings in server applications, allows building a flexible test environment and prepares for data transfer to the cloud. ![]()
