+@node disk_images_sheepdog
+@subsection Sheepdog disk images
+
+Sheepdog is a distributed storage system for QEMU. It provides highly
+available block level storage volumes that can be attached to
+QEMU-based virtual machines.
+
+You can create a Sheepdog disk image with the command:
+@example
+qemu-img create sheepdog:@var{image} @var{size}
+@end example
+where @var{image} is the Sheepdog image name and @var{size} is its
+size.
+
+To import the existing @var{filename} to Sheepdog, you can use a
+convert command.
+@example
+qemu-img convert @var{filename} sheepdog:@var{image}
+@end example
+
+You can boot from the Sheepdog disk image with the command:
+@example
+qemu sheepdog:@var{image}
+@end example
+
+You can also create a snapshot of the Sheepdog image like qcow2.
+@example
+qemu-img snapshot -c @var{tag} sheepdog:@var{image}
+@end example
+where @var{tag} is a tag name of the newly created snapshot.
+
+To boot from the Sheepdog snapshot, specify the tag name of the
+snapshot.
+@example
+qemu sheepdog:@var{image}:@var{tag}
+@end example
+
+You can create a cloned image from the existing snapshot.
+@example
+qemu-img create -b sheepdog:@var{base}:@var{tag} sheepdog:@var{image}
+@end example
+where @var{base} is a image name of the source snapshot and @var{tag}
+is its tag name.
+
+If the Sheepdog daemon doesn't run on the local host, you need to
+specify one of the Sheepdog servers to connect to.
+@example
+qemu-img create sheepdog:@var{hostname}:@var{port}:@var{image} @var{size}
+qemu sheepdog:@var{hostname}:@var{port}:@var{image}
+@end example
+
+@node disk_images_iscsi
+@subsection iSCSI LUNs
+
+iSCSI is a popular protocol used to access SCSI devices across a computer
+network.
+
+There are two different ways iSCSI devices can be used by QEMU.
+
+The first method is to mount the iSCSI LUN on the host, and make it appear as
+any other ordinary SCSI device on the host and then to access this device as a
+/dev/sd device from QEMU. How to do this differs between host OSes.
+
+The second method involves using the iSCSI initiator that is built into
+QEMU. This provides a mechanism that works the same way regardless of which
+host OS you are running QEMU on. This section will describe this second method
+of using iSCSI together with QEMU.
+
+In QEMU, iSCSI devices are described using special iSCSI URLs
+
+@example
+URL syntax:
+iscsi://[<username>[%<password>]@@]<host>[:<port>]/<target-iqn-name>/<lun>
+@end example
+
+Username and password are optional and only used if your target is set up
+using CHAP authentication for access control.
+Alternatively the username and password can also be set via environment
+variables to have these not show up in the process list
+
+@example
+export LIBISCSI_CHAP_USERNAME=<username>
+export LIBISCSI_CHAP_PASSWORD=<password>
+iscsi://<host>/<target-iqn-name>/<lun>
+@end example
+
+Various session related parameters can be set via special options, either
+in a configuration file provided via '-readconfig' or directly on the
+command line.
+
+@example
+Setting a specific initiator name to use when logging in to the target
+-iscsi initiator-name=iqn.qemu.test:my-initiator
+@end example
+
+@example
+Controlling which type of header digest to negotiate with the target
+-iscsi header-digest=CRC32C|CRC32C-NONE|NONE-CRC32C|NONE
+@end example
+
+These can also be set via a configuration file
+@example
+[iscsi]
+ user = "CHAP username"
+ password = "CHAP password"
+ initiator-name = "iqn.qemu.test:my-initiator"
+ # header digest is one of CRC32C|CRC32C-NONE|NONE-CRC32C|NONE
+ header-digest = "CRC32C"
+@end example
+
+
+Setting the target name allows different options for different targets
+@example
+[iscsi "iqn.target.name"]
+ user = "CHAP username"
+ password = "CHAP password"
+ initiator-name = "iqn.qemu.test:my-initiator"
+ # header digest is one of CRC32C|CRC32C-NONE|NONE-CRC32C|NONE
+ header-digest = "CRC32C"
+@end example
+
+
+Howto use a configuration file to set iSCSI configuration options:
+@example
+cat >iscsi.conf <<EOF
+[iscsi]
+ user = "me"
+ password = "my password"
+ initiator-name = "iqn.qemu.test:my-initiator"
+ header-digest = "CRC32C"
+EOF
+
+qemu-system-i386 -drive file=iscsi://127.0.0.1/iqn.qemu.test/1 \
+ -readconfig iscsi.conf
+@end example
+

+Howto set up a simple iSCSI target on loopback and accessing it via QEMU:
+@example
+This example shows how to set up an iSCSI target with one CDROM and one DISK
+using the Linux STGT software target. This target is available on Red Hat based
+systems as the package 'scsi-target-utils'.

basic example.
+@node pcsys_other_devs
+@section Other Devices
+
+@subsection Inter-VM Shared Memory device
+
+With KVM enabled on a Linux host, a shared memory device is available. Guests
+map a POSIX shared memory region into the guest as a PCI device that enables
+zero-copy communication to the application level of the guests. The basic
+syntax is:
+
+@example
+qemu -device ivshmem,size=<size in format accepted by -m>[,shm=<shm name>]
+@end example
+
+If desired, interrupts can be sent between guest VMs accessing the same shared
+memory region. Interrupt support requires using a shared memory server and
+using a chardev socket to connect to it. The code for the shared memory server
+is qemu.git/contrib/ivshmem-server. An example syntax when using the shared
+memory server is:
+
+@example
+qemu -device ivshmem,size=<size in format accepted by -m>[,chardev=<id>]
+ [,msi=on][,ioeventfd=on][,vectors=n][,role=peer|master]
+qemu -chardev socket,path=<path>,id=<id>
+@end example
+
+When using the server, the guest will be assigned a VM ID (>=0) that allows guests
+using the same server to communicate via interrupts. Guests can read their
+VM ID from a device register (see example code). Since receiving the shared
+memory region from the server is asynchronous, there is a (small) chance the
+guest may boot before the shared memory is attached. To allow an application
+to ensure shared memory is attached, the VM ID register will return -1 (an
+invalid VM ID) until the memory is attached. Once the shared memory is
+attached, the VM ID will return the guest's valid VM ID. With these semantics,
+the guest application can check to ensure the shared memory is attached to the
+guest before proceeding.
+
+The @option{role} argument can be set to either master or peer and will affect
+how the shared memory is migrated. With @option{role=master}, the guest will
+copy the shared memory on migration to the destination host. With
+@option{role=peer}, the guest will not be able to migrate with the device attached.
+With the @option{peer} case, the device should be detached and then reattached
+after migration using the PCI hotplug support.

-In order to launch a Mac OS X/Darwin process, QEMU needs the process executable
-itself and all the target dynamic libraries used by it. If you don't have the FAT
-libraries (you're running Mac OS X/ppc) you'll need to obtain it from a Mac OS X
-CD or compile them by hand.
