29 29 * Xen network backend - ioemu version.
30 30 *
31 31 * HVM guest domains use an emulated network device (typically the
32 32 * rtl8139) to access the physical network via IO emulation running in
33 33 * a backend domain (generally domain 0).
34 34 *
35 35 * The IO emulation code sends and receives packets using DLPI, usually
36 36 * through a virtual NIC (vnic).
37 37 *
38 38 * The creation of the relevant vnic to correspond to the network interface
39 39 * in the guest domain requires the use of 'hotplug' scripts in the backend
40 40 * domain. This driver ensures that the hotplug scripts are run when
41 41 * such guest domains are created.
42 42 *
43 43 * It is used as a result of the 'compatible' property associated with
44 44 * IO emulated devices. See /etc/driver_aliases and common/xen/os/xvdi.c.
