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 ...
GNOME Boxes was initially introduced as beta software in GNOME 3.3 (development branch for 3.4) as of Dec 2011, [5] and as a preview release in GNOME 3.4. [6] Its primary functions were as a virtual machine manager, remote desktop client (over VNC), and remote filesystem browser, utilizing the libvirt, libvirt-glib, and libosinfo technologies. [7]
The Linux console (and Linux virtual consoles) are implemented by the VT (virtual terminal) subsystem of the Linux kernel, and do not rely on any user space software. [3] This is in contrast to a terminal emulator , which is a user space process that emulates a terminal, and is typically used in a graphical display environment.
KVM (Kernel-based Virtual Machine) is a FreeBSD and Linux kernel module that allows a user space program access to the hardware virtualization features of various processors, with which QEMU can offer virtualization for x86, PowerPC, and S/390 guests. When the target architecture is the same as the host architecture, QEMU can make use of KVM ...
Starting from the PVE v.6.0 Corosync v.3.x is in use (not compatible with the earlier PVE versions). Individual virtual servers can be configured for high availability, using the built-in ha-manager. [28] [29] If a Proxmox node becomes unavailable or fails, the virtual servers can be automatically moved to another node and restarted. [30]
In open systems, a virtual terminal (VT) is an application service that: Allows host terminals on a multi-user network to interact with other hosts regardless of terminal type and characteristics, Allows remote log-on by local area network managers for the purpose of management,
A hypervisor, also known as a virtual machine monitor (VMM) or virtualizer, is a type of computer software, firmware or hardware that creates and runs virtual machines. A computer on which a hypervisor runs one or more virtual machines is called a host machine , and each virtual machine is called a guest machine .
While the Virtual Machine Manager project itself lacks documentation, there are third parties providing relevant information, e.g.: Red Hat Enterprise Linux virtualization 7 documentation (VMM is not used in RHEL 8 and later): Getting Started with Virtual Machine Manager; Fedora documentation: Getting started with virtualization
