Responsibilities of the hypervisor include memory management and CPU scheduling of all virtual machines ("domains"), and for launching the most privileged domain ("dom0") - the only virtual machine which by default has direct access to hardware.
From the dom0 the hypervisor can be managed and unprivileged domains ("dom U") can be launched.
For example, a system is considered scalable if it is capable of increasing its total output under an increased load when resources (typically hardware) are added.
An analogous meaning is implied when the word is used in an economic context, where a company's scalability implies that the underlying business model offers the potential for economic growth within the company.
Unlike all the other Linux software which is loaded when the NAS boots, this file is located on Volume_1 of the hard disk rather than within the flash memory.
This means the user can easily and safely modify the file because the contents of the flash memory is not changed.
Today, mice, printers, scanners, digital cameras, CD-RW drives, and many other devices can interface to computers via USB.
Thus, being able to configure USB devices to work with Linux is an important skill.
User domains may either be traditional operating systems, such as Microsoft Windows under which privileged instructions are provided by hardware virtualization instructions (if the host processor supports x86 virtualization, e.g., Intel VT-x and AMD-V), or para-virtualized operating systems whereby the operating system is aware that it is running inside a virtual machine, and so makes hypercalls directly, rather than issuing privileged instructions.
USB was designed to permit relatively painless hot-plug operation, meaning that devices can be plugged into the computer and unplugged while the computer operates.
Unfortunately, this type of operation is alien to Linux's basic driver model.
) is a hypervisor using a microkernel design, providing services that allow multiple computer operating systems to execute on the same computer hardware concurrently.
It was developed by the Linux Foundation and is supported by Intel.
A Berlin-based developer named “Fonz” created a package called “” (Fonz fun_plug), which includes the script and some extra software which can be invoked by fun_plug.
