KVM Architecture
In the KVM architecture the virtual machine is implemented as regular Linux process, schedule by the
standard Linux scheduler. In fact each virtual CPU appears as a regular Linux process. This allows KVM to
benefit from all the features of the Linux kernel.
Device emulation is handle by a modified version of QEMU that provides an emulated BIOS, PCI bus, USB bus and a standard set of devices such as IDE and SCSI disk controllers, network cards, etc.
