Server virtualization with KVM

Linux System Administration

Virtualization types on x86 platform Operating system virtualization. The system runs with a single Kernel; applications run within 'containers' like on different operating systems. Example: Solaris zones, LXC linux containers, Linux OpenVZ, Docker containers. Hardware Emulation (Full virtualization). A hypervisor presents an emulated hardware to unmodified guest operating systems. Example: VMware desktop/server, VirtualBox, QEMU. Paravirtualization. A hypervisor multiplexes access to hardware by modified guest operating systems. Example: Xen. A hardware assist virtualization on re-designed x86 platforms, such as AMD-V and Intel-VT. Example: KVM, VirtualBox, VMware ESX, Hyper-V
