OpenVMS, often referred to as just VMS, [9] is a multi-user, multiprocessing and virtual memory-based operating system. It is designed to support time-sharing , batch processing , transaction processing and workstation applications. [ 10 ]
e. In computing, a virtual machine (VM) is the virtualization or emulation of a computer system. Virtual machines are based on computer architectures and provide the functionality of a physical computer. Their implementations may involve specialized hardware, software, or a combination of the two. Virtual machines differ and are organized by ...
VAX. VAX (an acronym for Virtual Address eXtension) is a series of computers featuring a 32-bit instruction set architecture (ISA) and virtual memory that was developed and sold by Digital Equipment Corporation (DEC) in the late 20th century. The VAX-11/780, introduced October 25, 1977, was the first of a range of popular and influential ...
A system virtual machine (also called SYS-VM [citation needed]) is a virtual machine (VM) that provides a complete system platform and supports the execution of a complete operating system (OS). [1] These usually emulate an existing architecture, and are built with the purpose of either providing a platform to run programs where the real ...
PVM (VM/Pass-Through Facility) – a facility that provides remote access to other VM systems. TCPIP, SMTP, FTPSERVE, PORTMAP, VMNFS – a set of service machines that provide TCP/IP networking to VM/CMS. Db2 Server for VM – a SQL database system, the servers are often named similarly to "SQLMACH" and "SQLMSTR".
It enables users to set up virtual machines (VMs) on a single physical machine and use them simultaneously along with the host machine. Each virtual machine can execute its own operating system, including versions of Microsoft Windows, Linux, BSD, and MS-DOS. VMware Workstation is developed and sold by VMware, Inc.
Officially Hyper-V does not support the host/root operating system's optical drives to pass-through in guest VMs. As a result, burning to discs, audio CDs, video CD/DVD-Video playback are not supported; however, a workaround exists using the iSCSI protocol. Setting up an iSCSI target on the host machine with the optical drive can then be talked ...
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 ...
