Live migration, also called migration, refers to the process of moving a running virtual machine (VM) or application between different physical machines without disconnecting the client or application. Memory, storage, and network connectivity of the virtual machine are transferred from the original guest machine to the destination.
In the context of virtualization, where a guest simulation of an entire computer is actually merely a software virtual machine (VM) running on a host computer under a hypervisor, migration (also known as teleportation, [1] also known as live migration) is the process by which a running virtual machine is moved from one physical host to another, with little or no disruption in service.
Quest vConverter is an example of a fully automated migration tool for P2V. System Center Virtual Machine Manager SCVMM among many other capabilities has P2V capability. Leostream is an example of a fully automated migration tool for P2V. PlateSpin Migrate is an example of a fully automated migration tool for P2V (and V2P, V2V or P2P).
Oracle VirtualBox (formerly Sun VirtualBox, Sun xVM VirtualBox and InnoTek VirtualBox) is a hosted hypervisor for x86 virtualization developed by Oracle Corporation. VirtualBox was originally created by InnoTek Systemberatung GmbH, which was acquired by Sun Microsystems in 2008, which was in turn acquired by Oracle in 2010.
Platform virtualization software, specifically emulators and hypervisors, are software packages that emulate the whole physical computer machine, often providing multiple virtual machines on one physical platform. The table below compares basic information about platform virtualization hypervisors.
Kernel-based Virtual Machine (KVM) is a free and open-source virtualization module in the Linux kernel that allows the kernel to function as a hypervisor. It was merged into the mainline Linux kernel in version 2.6.20, which was released on February 5, 2007. [1] KVM requires a processor with hardware virtualization extensions, such as Intel VT ...
Vagrant is a source-available software product for building and maintaining portable virtual software development environments; [5] e.g., for VirtualBox, KVM, Hyper-V, Docker containers, VMware, Parallels, and AWS. It tries to simplify the software configuration management of virtualization in order to increase development productivity.
The creation and management of virtual machines has also been called "platform virtualization", or "server virtualization", more recently. [2] [3] Platform virtualization is performed on a given hardware platform by host software (a control program), which creates a simulated computer environment, a virtual machine (VM), for its guest software ...
