Overview
Operating system and processes run as processes on the host kernel
Hardware is emulated
- Disks - files in the host filesystem
- Terminals - xterms and ptys
- Network devices - slip and ethertap devices
- Serial lines - ptys
Runs as normal user
Notes:
Both the OS and its processes run as processes on the host kernel. Its hardware is virtual. A block device is emulated inside a file in the host filesystem. Consoles and serial lines are impemented by ptys in the host. There are also two network drivers, one implemented in terms of a slip device in the host, the other as an ethertap device.
