NetBSD 6.1.5 - man page for xbd (netbsd section 4)

XBD(4)				   BSD Kernel Interfaces Manual 			   XBD(4)

NAME
     xbd -- Xen frontend paravirtualized block device interface

SYNOPSIS
     xbd* at xenbus?

DESCRIPTION
     The xbd interface forms the frontend part of the paravirtualized drivers used by Xen guest
     domains to have a block device interface.

     From a guest point of view, xbd is similar to a hard disk, and can be treated in the very
     same way regarding partitioning, file systems creation and usage, and mounting.  By default,
     a NetBSD guest domain will assume that ``xbd0a'' serves as the root file system.

     When the host is NetBSD, the xbd interface is backed by a xbdback(4) interface.  In the Xen-
     Store, xbd and xbdback are identified by ``vbd'' (virtual block device) entries.

DIAGNOSTICS
     xbd%d: using event channel %d  Specifies the event channel used by this xbd interface.

     xbd%d: %s MB, %d bytes/sect x %u sectors  Gives the total size of the xbd block device, its
     sector size and total number of sectors.

     xbd%d: WARNING: cache flush not supported by backend  The backend driver associated with
     this xbd device does not support cache flushing operation.  This can be problematic for file
     system operations that require cache sync to avoid data loss or corruption.

SEE ALSO
     xbdback(4), xenbus(4), dkctl(8)

HISTORY
     The xbd driver first appeared in NetBSD 3.0.

AUTHORS
     The xbd driver was written by Manuel Bouyer <bouyer@NetBSD.org>.
