Structure of monolithic kernel and microkernel-based operating systems, respectively. Reflecting on the nature of monolithic kernel based systems, where a driver (which has, according to Minix creator Tanenbaum, approximately 3–7 times as many bugs as a usual program) [17] can bring down the whole system, [18] Minix 3 aims to create an operating system that is a "reliable, self-healing ...
In embedded systems, a board support package (BSP) is the layer of software containing hardware-specific boot loaders, device drivers and other routines that allow a given embedded operating system, for example a real-time operating system (RTOS), to function in a given hardware environment (a motherboard), integrated with the embedded operating system.

VMware ESXi (formerly ESX) is an enterprise-class, type-1 hypervisor developed by VMware, a subsidiary of Broadcom, for deploying and serving virtual computers.As a type-1 hypervisor, ESXi is not a software application that is installed on an operating system (OS); instead, it includes and integrates vital OS components, such as a kernel.
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]
Should the guest system become unusable (through virus attack, accidental system destruction, etc.), the user can delete the overlay and use an earlier emulated disk image. QEMU can emulate network cards (of different models) that share the host system's connectivity by translating network addresses, effectively allowing the guest to use the ...
During system initialization, BIOS determines the base address for this "stolen" address region and communicates it to the root complex and to the operating system. Each device has its own 4 KB space and each device's info is accessible through a simple array dev[bus][device][function] so that 256 MB of physical contiguous space is "stolen" for ...
A Java open source VMFS driver [9] enables read-only access to files and folders on partitions formatted with the Virtual Machine File System (VMFS) is developed and maintained by fluid Operations Archived 2011-08-21 at the Wayback Machine AG. It allows features like offloaded backups of virtual machines hosted on VMware ESXi hosts up to VMFSv3.
