1 Xen is a virtual machine monitor which supports running multiple guests
2 operating systems on a single machine. Guest OSes (also called "domains")
3 require a modified kernel which supports Xen hypercalls in replacement to access
4 to the physical hardware. At boot, the xen kernel is loaded along with the guest
5 kernel for the first domain (called domain0). domain0 has privileges to access
6 the physical hardware (PCI and ISA devices), administrate other domains and
7 provide virtual devices (disks and network) to other domains.
9 This package contains the Xen4 kernel itself.
