'''User-mode Linux''' ('''UML''') is an architectural [[porting|port]] of the [[Linux kernel]] to its own [[system call]] interface, which enables multiple virtual Linux kernel-based operating systems (known as guests) to run as an application within a normal Linux system (known as the host). A Linux kernel compiled for the ''um'' architecture can then boot as a process under another Linux kernel, entirely in [[User space and kernel space|user space]], without affecting the host environment's configuration or stability.

AsThis each guest is just amethod normal application running as a process in user space, this approach providesgives the user with a way ofto runningrun multiplemany virtual Linux machines on a single piece of hardware, offeringallowing some isolation, generallytypically without affectingchanging the configuration or stability of the host environment's configurationbecause oreach stabilityguest is just a regular application running as a process in user space.
