New Revision: 263105
URL: http://svnweb.freebsd.org/changeset/base/263105

Log:
  Add hyperv manual pages provided by Microsoft, formatted
  for FreeBSD standards.  Very little, if any, content was
  modified.
  
  These are not yet linked to the build.

+To compile this driver into the kernel, place the following lines in

+.Cd "device hyperv"
+.Ed
+.Sh DESCRIPTION
+The
+.Nm
+driver prevents the native
+.Fx
+ATA driver from
+loading in the presence of Hyper-V.
+.Fx
+guests running on Hyper-V can take advantage of the Hyper-V Storage
+Virtual Consumer
+.Pq Xr hv_storvsc 4
+for using their IDE devices.
+Since the ATA
+driver serves IDE devices as well, there is a chance that the ATA driver may
+interfere with the operations of
+.Xr hv_storvsc 4 .
+The
+.Nm
+driver avoids
+conflicts between the ATA driver and
+.Xr hv_storvsc 4
+by disabling the ATA driver
+when the
+.Fx
+guest is booting.
+.Pp
+A side effect of disabling the ATA driver is that CDROM may become
+inoperational on
+.Fx
+guest partitions.
+If CDROM access is a must then users may use
+"set hw.ata.disk_enable=1" at boot time to prevent the ATA driver from being
+disabled.

+.Sh SYNOPSIS
+To compile this driver into the kernel, place the following lines in

+.Bd -ragged -offset indent
+.Cd "device hyperv"
+.Ed
+.Sh DESCRIPTION
+The
+.Nm
+provides a high performance communication interface between
+guest and root partitions in Hyper-V.
+Hyper-V is a hypervisor-based virtualization technology from Microsoft.
+Hyper-V supports isolation in terms of a partition.
+A partition is a
+logical unit of isolation, supported by the hypervisor, in which
+operating systems execute.
+.Pp
+The Microsoft hypervisor must have at least one parent, or root,
+partition, running Windows Server operating system.
+The virtualization stack runs in the parent partition and has
+direct access to the hardware devices.
+The root partition then creates the child partitions which host
+the guest operating systems.
+.Pp
+Child partitions do not have direct access to other hardware resources
+and are presented
+a virtual view of the resources, as virtual devices (VDevs).
+Requests to the virtual devices are
+redirected either via the VMBus or the hypervisor to the devices in
+the parent partition, which handles the requests.
+.Pp
+The VMBus is a logical inter-partition communication channel.
+The parent partition hosts Virtualization Service Providers (VSPs)
+which communicate over the VMBus to handle device access requests from
+child partitions.
+Child partitions host Virtualization Service
+Consumers (VSCs) which redirect device requests to VSPs in the parent
+partition via the VMBus.
+The Hyper-V VMBus driver defines and implements
+the interface that facilitate high performance bi-directional communication
+between the VSCs and VSPs.
+All VSCs utilize the VMBus driver.
