[PATCH 01 of 15 v2] Replace references to old wiki with ones to new
# HG changeset patch
# User Ian Campbell <ian.campbell@citrix.com>
# Date 1322221956 0
# Node ID 732154549538fe983a8cc6ea74605e04e8ea0a64
# Parent 1027e7d13d02143048c7d48d7960967c5b1657a8
Replace references to old wiki with ones to new.
I have confirmed that the relevant pages have been transitioned.
What remains is pages which have not yet been moved over:
$ rgrep xenwiki *
docs/misc/xenstore.txt: See http://wiki.xensource.com/xenwiki/XenBus section
tools/libxen/README:http://wiki.xensource.com/xenwiki/XenApi
tools/xenballoon/xenballoond.README:http://wiki.xensource.com/xenwiki/Open_Topics_For_Discussion?action=AttachFile&do=get&target=Memory+Overcommit.pdf
Note that "PythonInXlConfig" never existed in the old wiki and does
not exist
in the new. This reference was introduced by 22735:cb94dbe20f97 and was
supposed to have been written prior to the 4.1 release. I have transitioned it
anyway but it''s not clear how valuable the message actually is. Perhaps
we
should just remove that aspect of it?

I believe that all keys are now present in the document although there are are
various omissions in the actual documentation of them. Hopefully however this
covers the majority of the most interesting keys.

+=head1 NAME
+
+xl.cfg - XL Domain Configuration File Syntax
+
+=head1 SYNOPSIS
+
+ /etc/xen/xldomain
+
+=head1 DESCRIPTION
+
+To create a VM (a domain in Xen terminology, sometimes called a guest)
+with xl requires the provision of a domain config file. Typically
+these live in `/etc/xen/DOMAIN.cfg` where DOMAIN is the name of the
+domain.
+
+=head1 SYNTAX
+
+A domain config file consists of a series of C<KEY=VALUE> pairs.
+
+Some C<KEY>s are mandatory, others are global options which apply to
+any guest type while others relate only to specific guest types
+(e.g. PV or HVM guests).
+
+A value C<VALUE> is one of:
+
+=over 4
+
+=item B<"STRING">
+
+A string, surrounded by either single or double quotes.
+
+=item B<NUMBER>
+
+A number, in either decimal, octal (using a C<0> prefix) or
+hexadecimal (using an C<0x> prefix).
+
+=item B<BOOLEAN>
+
+A C<NUMBER> interpreted as C<False> (C<0>) or C<True>
(any other
+value).
+
+=item B<[ VALUE, VALUE, ... ]>
+
+A list of C<VALUES> of the above types. Lists are homogeneous and are
+not nested.
+
+=back
+
+The semantics of each C<KEY> defines which form of C<VALUE> is
required.
+
+=head1 OPTIONS
+
+=head2 Mandatory Configuration Items
+
+The following key is mandatory for any guest type:
+
+=over 4
+
+=item B<name="NAME">
+

+=item B<builder="generic">
+
+Specifies that this is to be a PV domain. This is the default.
+
+=item B<builder="hvm">
+
+Specifies that this is to be an HVM domain. That is, a fully
+virtualised computer with emulated BIOS, disk and network peripherals,
+etc. The default is a PV domain, suitable for hosting Xen-aware guest
+operating systems.
+
+=back
+
+=head2 Global Options
+
+The following options apply to guests of any type.
+
+=over 4
+
+=item B<uuid="UUID">
+
+Specifies the UUID of the domain. If not specified, a fresh unique
+UUID will be generated.
+
+=item B<pool="CPUPOOLNAME">
+
+Put the guest''s vcpus into the named cpu pool.
+
+=item B<vcpus=N>
+
+Start the guest with N vcpus initially online.
+
+=item B<maxvcpus=M>
+
+Allow the guest to bring up a maximum of M vcpus. At start of day if
+`vcpus=N` is less than `maxvcpus=M` then the first `N` vcpus will be
+created online and the remainder will be offline.
+
+=item B<memory=MBYTES>
+
+Start the guest with MBYTES megabytes of RAM.
+
+=item B<on_poweroff="ACTION">
+
+Specifies what should be done with the domain if it shuts itself down.
+The C<ACTION>s are:

+write a "coredump" of the domain to F</var/xen/dump/NAME> and
then
+destroy the domain.
+
+=item B<coredump-restart>
+
+write a "coredump" of the domain to F</var/xen/dump/NAME> and
then
+restart the domain.
+
+=back
+
+The default for C<on_poweroff> is C<destroy>.

+
+Action to take if the domain shuts down with a reason code requesting
+a reboot. Default is C<restart>.
+
+=item B<on_watchdog="ACTION">

+Action to take if the domain crashes. Default is C<destroy>.
+
+=item B<seclabel="LABEL">
+
+Assign an XSM security label to this domain.

+=over 4
+
+=item B<disk=[ "DISK_SPEC_STRING", "DISK_SPEC_STRING",
...]>
+
+Specifies the disks (both emulated disks and Xen virtual block
+devices) which are to be provided to the guest, and what objects on

+
+=item B<vif=[ "NET_SPEC_STRING", "NET_SPEC_STRING",

+an HVM guest. See L<Emulated VGA Graphics Device> below for how to
+configure the emulated device.
+
+Each B<VFB_SPEC_STRING> is a comma-separated list of C<KEY=VALUE>
+settings, from the following list:
+
+=over 4
+
+=item C<vnc=BOOLEAN>
+
+Allow access to the display via the VNC protocol. This enables the
+other VNC-related settings. The default is to enable this.
+
+=item C<vnclisten="ADDRESS[:DISPLAYNUM]">
+
+Specifies the IP address, and optionally VNC display number, to use.
+
+=item C<vncdisplay=DISPLAYNUM>
+
+Specifies the VNC display number to use. The actual TCP port number
+will be DISPLAYNUM+5900.
+
+=item C<vncunused=BOOLEAN>
+
+Requests that the VNC display setup search for a free TCP port to use.
+The actual display used can be accessed with C<xl vncviewer>.
+
+=item C<vncpasswd="PASSWORD">
+
+Specifies the password for the VNC server.
+
+=item C<sdl=BOOLEAN>
+
+Specifies that the display should be presented via an X window (using
+Simple DirectMedia Layer). The default is to not enable this mode
+
+=item C<opengl=BOOLEAN>
+
+Enable OpenGL acceleration of the SDL display. Only effects machines
+using C<device_model_version="qemu-xen-traditonal"> and only if
the
+device-model was compiled with OpenGL support. Disabled by default.
+
+=item C<keymap="LANG">
+
+Configure the keymap to use for the keyboard associated with this
+display. If the input method does not easily support raw keycodes
+(e.g. this is often the case when using VNC) then this allows us to
+correctly map the input keys into keycodes seen by the guest. The
+specific values which are accepted are defined by the version of the
+device-model which you are using. See L<Keymaps> below or consult the
+L<qemu(1)> manpage. The default is B<en-us>.

+(B<DDDD>), Bus (B<BB>), Device (B<DD>) and Function
(B<F>) syntax. This is
+the same scheme as used in the output of C<lspci> for the device in
+question. Note: By default C<lspci> will omit the domain (B<DDDD>)
if it
+is zero and it is optional here also. You may specify the function
+(B<F>) as B<*> to indicate all functions.
+
+=item B<@VSLOT>
+
+specifies the virtual device where the guest will see this
+device. This is equivalent to the B<DD> which the guest sees. In a
+guest B<DDDD> and B<BB> are C<0000:00>. XXX how does this
really work?

+
+The following options apply only to Paravirtual guests.
+
+=over 4
+
+=item B<kernel="PATHNAME">
+
+Load the specified file as the kernel image. Either B<kernel> or
+B<bootloader> must be specified for PV guests.
+
+=item B<ramdisk="PATHNAME">
+
+Load the specified file as the ramdisk.
+
+=item B<bootloader="PROGRAM">
+
+Run C<PROGRAM> to find the kernel image and ramdisk to use. Normally
+C<PROGRAM> would be C<pygrub>, which is an emulation of
+grub/grub2/syslinux.
+
+=item B<bootloader_args=STRING>
+
+Append B<STRING> (split into words at whitespace) to the arguments to
+the B<bootloader> program. XXX this should be a list of strings.
+
+=item B<root="STRING">
+
+Append B<root="STRING"> to the kernel command line (Note: it is
guest
+specific what meaning this has).
+
+=item B<extra="STRING">
+
+Append B<STRING> to the kernel command line. Note: it is guest
+specific what meaning this has).
+
+=item B<e820_host=BOOLEAN>
+
+Selects whether to expose the host e820 (memory map) to the guest via
+the virtual e820. When this option is false the guest psuedo-physical
+address space consists of a single contiguous RAM region. When this
+option is specified the virtual e820 instead reflects the host e820
+and contains the same PCI holes. The total amount of RAM represented
+by the memory map is always the same, this option configures only how
+it is layed out.
+
+Exposing the host e820 to the guest gives the guest kernel the
+opportunity to set aside the required part of its pseudo-physical
+address space in order to provide address space to map passedthrough
+PCI devices. It is guest Operaring System dependant whether this
+option is required, specifically it is required when using a mainline
+Linux ("pvops") kernel. This option defaults to true if any PCI
+passthrough devices are configued and false otherwise. If you do not
+configure any passthrough devices at domain creation time but expect

+=head2 Fully-virtualised (HVM) Guest Specific Options
+
+The following options apply only to HVM guests.
+
+=head3 Boot Device
+
+=over 4
+
+=item B<boot=[c|d|n]>
+
+Selects the emulated virtual device to boot from. Options are hard
+disk (B<c>), cd-rom (B<d>) or network/PXE (B<n>). Multiple
options can be
+given and will be attempted in the order they are given. e.g. to boot
+from cd-rom but fallback to the hard disk you can give B<dc>. The
+default is B<cd>.
+
+=back
+
+=head3 Paging
+
+The following options control the mechanisms used to virtualise guest
+memory. The defaults are selected to give the best results for the
+common case and so you should normally leave these options
+unspecified.
+
+=over 4
+
+=item B<hap=BOOLEAN>
+
+Turns "hardware assisted paging" (the use of the hardware nested page
+table feature) on or off. This feature is called EPT (Extended Page
+Tables) by Intel and NPT (Nested Page Tables) or RVI (Rapid
+Virtualisation Indexing) by AMD. Affects HVM guests only. If turned
+off, Xen will run the guest in "shadow page table" mode where the
+guest''s page table updates and/or TLB flushes etc. will be emulated.
+Use of HAP is the default when available.
+
+=item B<oos=BOOLEAN>
+
+Turns "out of sync pagetables" on or off. When running in shadow
page
+table mode, the guest''s page table updates may be deferred as
+specified in the Intel/AMD architecture manuals. However this may
+expose unexpected bugs in the guest, or find bugs in Xen, so it is
+possible to disable this feature. Use of out of sync page tables,
+when Xen thinks it appropriate, is the default.
+
+=item B<shadow_memory=MBYTES>
+
+Number of megabytes to set aside for shadowing guest pagetable pages
+(effectively acting as a cache of translated pages) or to use for HAP
+state. By default this is 1MB per guest vcpu plus 8KB per MB of guest
+RAM. You should not normally need to adjust this value. However if you
+are not using hardware assisted paging (i.e. you are using shadow
+mode) and your guest workload consists of a a very large number of
+similar processes then increasing this value may improve performance.
+
+=back
+
+=head3 Processor and Platform Features
+
+The following options allow various processor and platform level
+features to be hidden or exposed from the guest''s point of view. This
+can be useful when running older guest Operating Systems which may
+misbehave when faced with more modern features. In general you should
+accept the defaults for these options wherever possible.
+
+=over 4
+
+=item B<pae=BOOLEAN>
+
+Hide or expose the IA32 Physical Address Extensions. These extensions
+make it possible for a 32 bit guest Operating System to access more
+than 4GB of RAM. Enabling PAE also enabled other features such as
+NX. PAE is required if you wish to run a 64-bit guest Operating
+System. In general you should leave this enabled and allow the guest
+Operating System to choose whether or not to use PAE. (X86 only)
+
+=item B<acpi=BOOLEAN>
+
+Expose ACPI (Advanced Configuration and Power Interface) tables from
+the virtual firmware to the guest Operating System. ACPI is required
+by most modern guest Operating Systems. This option is enabled by
+default and usually you should omit it. However it may be necessary to
+disable ACPI for compatibility with some guest Operating Systems.
+
+=item B<apic=BOOLEAN>
+
+Include information regarding APIC (Advanced Programmable Interrupt
+Controller) in the firmware/BIOS tables on a single processor
+guest. This causes the MP (multiprocessor) and PIR (PCI Interrupt
+Routing) tables to be exported by the virtual firmware. This option
+has no effect on a guest with multiple virtual CPUS as they must
+always include these tables. This option is enabled by default and you
+should usually omit it but it may be necessary to disable these
+firmware tables when using certain older guest Operating
+Systems. These tables have been superceded by newer constructs within
+the ACPI tables. (X86 only)
+
+=item B<nx=BOOLEAN>
+
+Hides or exposes the No-eXecute capability. This allows a guest
+Operating system to map pages such that they cannot be executed which
+can enhance security. This options requires that PAE also be
+enabled. (X86 only)
+
+=item B<hpet=BOOLEAN>
+
+Enables or disables HPET (High Precision Event Timer). This option is
+enabled by default and you should usually omit it. It may be necessary
+to disable the HPET in order to improve compatibility with guest
+Operating Systems (X86 only)
+
+=item B<nestedhvm=BOOLEAN>
+
+Enable or disables guest access to hardware virtualisation features,
+e.g. it allows a guest Operating System to also function as a
+hypervisor. This option is disabled by default. You may want this
+option if you want to run another hypervisor (including another copy
+of Xen) within a Xen guest or to support a guest Operating System
+which uses hardware virtualisation extensions (e.g. Windows XP
+compatibility mode on more modern Windows OS).
+

+
+=head3 Guest Virtual Time Controls
+
+=over 4

+=item B<tsc_mode="MODE">
+
+Specifies how the TSC (Time Stamp Counter) should be provided to the
+guest. XXX ???
+
+=back
+
+=head3 Support for Paravirtualisation of HVM Guests
+
+The following options allow Paravirtualised features (such as devices)
+to be exposed to the guest Operating System in an HVM guest.
+Utilising these features requires specific guest support but when
+available they will result in improved performance.
+
+=over 4
+
+=item B<xen_platform_pci=BOOLEAN>
+
+Enable or disable the Xen platform PCI device. The presence of this
+virtual device enables a guest Operating System (subject to the
+availability of suitable drivers) to make use of paravirtualisation
+features such as disk and network devices etc. Enabling these drivers
+improves performance and is strongly recommended when available. PV
+drivers are available for various Operating Systems including HVM
+Linux L<http://wiki.xen.org/wiki/XenLinuxPVonHVMdrivers> and Microsoft
+Windows L<http://wiki.xen.org/wiki/XenWindowsGplPv>.
+
+=item B<viridian=BOOLEAN>
+
+Turns on or off the exposure of MicroSoft Hyper-V (AKA viridian)
+compatible enlightenments to the guest. These can improve performance
+of Microsoft Windows guests (XXX which versions of Windows benefit?)
+
+=back
+
+=head3 Emulated VGA Graphics Device
+
+The following options control the features of the emulated graphics
+device. Many of these options behave similarly to the equivalent key
+in the B<VFB_SPEC_STRING> for configuring virtual frame buffer devices
+(see above).
+
+=over 4
+
+=item B<videoram=MBYTES>
+
+Sets the amount of RAM which the emulated video card will contain,
+which in turn limits the resolutions and bit depths which will be
+available. This option is only available when using the B<stdvga>
+option (see below). The default is 8MB which is sufficient for
+e.g. 1600x1200 at 32bpp. When not using the B<stdvga> option the
+amount of video ram is fixed at 4MB which is sufficient for 1024x768
+at 32 bpp.
+
+=item B<stdvga=BOOLEAN>
+
+Select a standard VGA card with VBE (VESA BIOS Extensions) as the
+emulated graphics device. The default is false which means to emulate
+a Cirrus Logic GD5446 VGA card. If your guest supports VBE 2.0 or
+later (e.g. Windows XP onwards) then you should enable this.
+
+=item B<vnc=BOOLEAN>
+
+Allow access to the display via the VNC protocol. This enables the
+other VNC-related settings. The default is to enable this.
+
+=item B<vnclisten="ADDRESS[:DISPLAYNUM]">
+
+Specifies the IP address, and optionally VNC display number, to use.
+
+=item B<vncdisplay=DISPLAYNUM>
+
+Specifies the VNC display number to use. The actual TCP port number
+will be DISPLAYNUM+5900.
+
+=item B<vncunused=BOOLEAN>
+
+Requests that the VNC display setup search for a free TCP port to use.
+The actual display used can be accessed with C<xl vncviewer>.
+
+=item B<vncpasswd="PASSWORD">
+
+Specifies the password for the VNC server.
+
+=item B<keymap="LANG">
+
+Configure the keymap to use for the keyboard associated with this
+display. If the input method does not easily support raw keycodes
+(e.g. this is often the case when using VNC) then this allows us to
+correctly map the input keys into keycodes seen by the guest. The
+specific values which are accepted are defined by the version of the
+device-model which you are using. See L<Keymaps> below of consult the
+L<qemu(1)> manpage. The default is B<en-us>.
+
+=item B<sdl=BOOLEAN>
+
+Specifies that the display should be presented via an X window (using
+Simple DirectMedia Layer). The default is not to enable this mode.
+
+=item B<opengl=BOOLEAN>
+
+Enable OpenGL acceleration of the SDL display. Only effects machines
+using B<device_model_version="qemu-xen-traditonal"> and only if
the
+device-model was compiled with OpenGL support. Disabled by default.

+given if SPICE is enabled. NB. the options depending on spicetls_port
+have not been supported.
+
+=item B<spicedisable_ticketing=BOOLEAN>
+
+Enable client connection without password. The default is false. If
+it''s false (set to 0), spicepasswd must be set.
+
+=item B<spicepasswd="PASSWORD">
+
+Specify the ticket password which is used by a client for connection.

+
+Enables or disables a USB bus in the guest.
+
+=item B<usbdevice=DEVICE>
+
+Adds B<DEVICE> to the USB bus. The USB bus must also be enabled using
+B<usb=1>. The most common use for this option is
B<usbdevice=tablet>
+which adds pointer device using absolute coordinates. Such devices
+function better than relative coordinate devices (such as a standard
+mouse) since many methods of exporting guest graphics (such as VNC)
+work better in this mode. Note that this is independent of the actual
+pointer device you are using on the host/client side. XXX should/could
+be a list of devices.

+
+The following options control the selection of the device-model. This
+is the component which provides emulation of the virtual devices to an

[PATCH 08 of 15 v2] libxl: use named options for tsc_mode
# HG changeset patch
# User Ian Campbell <ian.campbell@citrix.com>
# Date 1322221982 0
# Node ID b0009f28bbf2ec313eead3ed36a2b139fa5f3512
# Parent 88eee947a2bd15d4811c664ba6ed345a066708eb
libxl: use named options for tsc_mode.
Add an enum at the libxl level with a hopefully descriptive set of names.
Deprecate the use of an integer in xl cfg files.

docs: remove non-breaking spaces from sedf_scheduler_mini-HOWTO.txt
This document contains several 0xa0 characters (non-breaking spaces). These do
not display correctly in (some) terminals or when the document is rendered by
(some)
browsers. Re-encode them as spaces.
I''m not confident that this change will make it through being encoded
as a patch
and sent through email. Its effect can be replicated with:
perl -i -p -e ''s/\xa0/ /g''

xl: make bootloader_args a list
This is much more natural. Continue to support the old syntax in xl but

I have confirmed that the relevant pages have been transitioned.

This reference was introduced by 22735:cb94dbe20f97 and was supposed to have been written prior to the 4.1 release. I have transitioned it anyway but it''s not clear how valuable the message actually is. Perhaps we should just remove that aspect of it?
