In both cases the device naming is subject to the usual guest or backend domain facilities for renaming network devices. Under Linux such devices are by default named vifDOMID.DEVID while under NetBSD xvifDOMID.DEVID is used. The backend device is typically named such that it contains both the guest domain ID and the index of the device. Under NetBSD and FreeBSD the frontend devices are named xennetN and xnN respectively. #Mac emulator 7th guest driverTypically under Linux it is bound to the xen-netfront driver and creates a device ethN. The frontend devices appear much like any other physical Ethernet NIC in the guest domain. A similar pair of devices is created for each virtual network interface The first of these (the frontend) will reside in the guest domain while the second (the backend) will reside in the backend domain (typically Dom0). #Mac emulator 7th guest driversvia PV on HVM drivers for Linux or the GPL PV drivers for Windows.Ī paravirtualised network device consists of a pair of network devices. In addition PV network drivers are available for various guest operating systems when running as a fully virtualised (HVM) guest, e.g. Drivers for PV network devices are available by default in most PV aware guest OS kernels. These PV interfaces enable fast and efficient network communications for domains without the overhead of emulating a real network device. Virtual Network Interfaces Paravirtualised Network DevicesĪ Xen guest typically has access to one or more paravirtualised (PV) network interfaces.
