-What is Xen?
-============
-
-Xen is a Virtual Machine Monitor (VMM) originally developed by the
-Systems Research Group of the University of Cambridge Computer
-Laboratory, as part of the UK-EPSRC funded XenoServers project. Xen
-is freely-distributable Open Source software, released under the GNU
-GPL. Since its initial public release, Xen has grown a large
-development community, spearheaded by XenSource Inc, a company created
-by the original Xen development team to build enterprise products
-around Xen.
-
-The 3.0 release offers excellent performance, hardware support and
-enterprise-grade features such as x86_32-PAE, x86_64, SMP guests and
-live relocation of VMs. This install tree contains source for a Linux
-2.6 guest; ports to Linux 2.4, NetBSD, FreeBSD and Solaris will follow
-later (and are already available for previous Xen releases).
-
-This file contains some quick-start instructions to install Xen on
-your system. For full documentation, see the Xen User Manual. If this
-is a pre-built release then you can find the manual at:
- dist/install/usr/share/doc/xen/pdf/user.pdf
-If you have a source release, then 'make -C docs' will build the
-manual at docs/pdf/user.pdf.
-
-Quick-Start Guide - Pre-Built Binary Release
-============================================
-
-[NB. Unless noted otherwise, all the following steps should be
-performed with root privileges.]
-
-1. Install the binary distribution onto your filesystem:
-
- # sh ./install.sh
-
- Among other things, this will install Xen and Xen-ready Linux
- kernel files in /boot, kernel modules and Python packages in /lib,
- and various control tools in standard 'bin' directories.
-
-2. Configure your bootloader to boot Xen and an initial Linux virtual
- machine. Note that Xen currently only works with GRUB and pxelinux
- derived boot loaders: less common alternatives such as LILO are
- *not* supported. You can most likely find your GRUB menu file at
- /boot/grub/menu.lst: edit this file to include an entry like the
- following:
-
- title Xen 3.0 / XenLinux 2.6
- kernel /boot/xen-3.0.gz console=vga
- module /boot/vmlinuz-2.6-xen root=<root-dev> ro console=tty0
- module /boot/initrd-2.6-xen.img
-
- NB: Not all kernel configs need an initial ram disk (initrd), but
- if you do specify one you'll need to use the 'module' grub directive
- rather than 'initrd'.
-
- The linux command line takes all the usual options, such as
- root=<root-dev> to specify your usual root partition (e.g.,
- /dev/hda1).
-
- The Xen command line takes a number of optional arguments described
- in the manual. The most common is 'dom0_mem=xxxM' which sets the
- amount of memory to allocate for use by your initial virtual
- machine (known as domain 0). Note that Xen itself reserves about
- 32MB memory for internal use, which is not available for allocation
- to virtual machines.
-
-3. Reboot your system and select the "Xen 3.0 / XenLinux 2.6" menu
- option. After booting Xen, Linux will start and your initialisation
- scripts should execute in the usual way.
-
-Quick-Start Guide - Source Release
-==================================
-
-First, there are a number of prerequisites for building a Xen source
-release. Make sure you have all the following installed, either by
-visiting the project webpage or installing a pre-built package
-provided by your Linux distributor:
- * GCC (preferably v3.2.x or v3.3.x; older versions are unsupported)
- * GNU Make
- * GNU Binutils
- * Development install of zlib (e.g., zlib-dev)
- * Development install of Python v2.3 or later (e.g., python-dev)
- * bridge-utils package (/sbin/brctl)
- * iproute package (/sbin/ip)
- * hotplug or udev
-
-[NB. Unless noted otherwise, all the following steps should be
-performed with root privileges.]
-
-1. Download and untar the source tarball file. This will be a
- file named xen-unstable-src.tgz, or xen-$version-src.tgz.
- You can also pull the current version from the SCMS
- that is being used (Bitkeeper, scheduled to change shortly).
-
- # tar xzf xen-unstable-src.tgz
-
- Assuming you are using the unstable tree, this will
- untar into xen-unstable. The rest of the instructions
- use the unstable tree as an example, substitute the
- version for unstable.
-
-2. cd to xen-unstable (or whatever you sensibly rename it to).
- The Linux, netbsd and freebsd kernel source trees are in
- the $os-$version-xen-sparse directories.
-
-On Linux:
-
-3. For the very first build, or if you want to destroy existing
- .configs and build trees, perform the following steps:
-
- # make KERNELS=linux-2.6-xen world
- # make install
-
- It will create and install into the dist/ directory which is the
- default install location. It will build the xen binary (xen.gz),
- and a linux kernel and modules that can be used in both dom0 and an
- unprivileged guest kernel (vmlinuz-2.6.x-xen), the tools and the
- documentation.
-
- If you don't specify KERNELS= on the make command line it will
- default to building two kernels, vmlinuz-2.6.x-xen0 and
- vmlinuz-2.6.x-xenU. These are smaller builds with just selected
- modules, intended primarilly for developers that don't like to wait
- for a -xen kernel to build. The -xenU kernel is particularly small
- as it does not contain any physical device drivers, and hence is
- only useful for guest domains.
-
- If you want to build an x86_32 PAE capable xen and kernel to work
- on machines with >= 4GB of memory, use XEN_TARGET_X86_PAE=y on the
- make command line.
-
-4. To rebuild an existing tree without modifying the config:
- # make dist
-
- This will build and install xen, kernels, tools, and
- docs into the local dist/ directory.
-
-5. To rebuild a kernel with a modified config:
-
- # make linux-2.6-xen-config CONFIGMODE=menuconfig (or xconfig)
- # make linux-2.6-xen-build
- # make linux-2.6-xen-install
-
- Depending on your config, you may need to use 'mkinitrd' to create
- an initial ram disk, just like a native system e.g.
- # depmod 2.6.12.6-xen
- # mkinitrd -v -f --with=aacraid --with=sd_mod --with=scsi_mod
initrd-2.6.12.6-xen.img 2.6.12.6-xen

+ version for unstable.
+
+2. cd to xen-unstable (or whatever you sensibly rename it to).
+ The Linux, netbsd and freebsd kernel source trees are in
+ the $os-$version-xen-sparse directories.
+
+On Linux:
+
+3. For the very first build, or if you want to destroy existing
+ .configs and build trees, perform the following steps:
+
+ # make world
+ # make install
+
+ This will create and install onto the local machine. It will build
+ the xen binary (xen.gz), and a linux kernel and modules that can be
+ used in both dom0 and an unprivileged guest kernel (vmlinuz-2.6.x-xen),
+ the tools and the documentation.
+
+ You can override the destination for make install by setting DESTDIR
+ to some value.
+
+ The make command line defaults to building the kernel vmlinuz-2.6.x-xen.
+ You can override this default by specifying KERNELS=kernelname. For
+ example, you can make two kernels - linux-2.6-xen0
+ and linux-2.6-xenU - which are smaller builds containing only selected
+ modules, intended primarily for developers that don't like to wait
+ for a full -xen kernel to build. The -xenU kernel is particularly small,
+ as it does not contain any physical device drivers, and hence is
+ only useful for guest domains.
+
+ To make these two kernels, simply specify
+
+ KERNELS="linux-2.6-xen0 linux-2.6-xenU"
+
+ in the make command line.
+
+ If you want to build an x86_32 PAE capable xen and kernel to work
+ on machines with >= 4GB of memory, use XEN_TARGET_X86_PAE=y on the
+ make command line.
+
+4. To rebuild an existing tree without modifying the config:
+ # make dist
+
+ This will build and install xen, kernels, tools, and
+ docs into the local dist/ directory.
+
+ You can override the destination for make install by setting DISTDIR
+ to some value.
+
+ make install and make dist differ in that make install does the
+ right things for your local machine (installing the appropriate
+ version of hotplug or udev scripts, for example), but make dist
+ includes all versions of those scripts, so that you can copy the dist
+ directory to another machine and install from that distribution.
+
+5. To rebuild a kernel with a modified config:
+
+ # make linux-2.6-xen-config CONFIGMODE=menuconfig (or xconfig)
+ # make linux-2.6-xen-build
+ # make linux-2.6-xen-install
+
+ Depending on your config, you may need to use 'mkinitrd' to create
+ an initial ram disk, just like a native system e.g.
+ # depmod 2.6.16-xen
+ # mkinitrd -v -f --with=aacraid --with=sd_mod --with=scsi_mod

+Subject: Increase x86 interrupt vector range
+
+Remove the limit of 256 interrupt vectors by changing the value
+stored in orig_{e,r}ax to be the negated interrupt vector.
+The orig_{e,r}ax needs to be < 0 to allow the signal code to
+distinguish between return from interrupt and return from syscall.
+With this change applied, NR_IRQS can be > 256.

-config DETECT_SOFTLOCKUP
- bool "Detect Soft Lockups"
- depends on DEBUG_KERNEL
- default y
- help
- Say Y here to enable the kernel to detect "soft lockups",
- which are bugs that cause the kernel to loop in kernel
- mode for more than 10 seconds, without giving other tasks a
- chance to run.
-
- When a soft-lockup is detected, the kernel will print the
- current stack trace (which you should report), but the
- system will stay locked up. This feature has negligible
- overhead.
-
- (Note that "hard lockups" are separate type of bugs that
- can be detected via the NMI-watchdog, on platforms that
- support it.)
-
-config SCHEDSTATS
- bool "Collect scheduler statistics"
- depends on DEBUG_KERNEL && PROC_FS
- help
- If you say Y here, additional code will be inserted into the
- scheduler and related routines to collect statistics about
- scheduler behavior and provide them in /proc/schedstat. These
- stats may be useful for both tuning and debugging the scheduler
- If you aren't debugging the scheduler or trying to tune a specific
- application, you can say N to avoid the very slight overhead
- this adds.
-
-config DEBUG_SLAB
- bool "Debug memory allocations"
- depends on DEBUG_KERNEL && SLAB
- help
- Say Y here to have the kernel do limited verification on memory
- allocation as well as poisoning memory on free to catch use of freed
- memory. This can make kmalloc/kfree-intensive workloads much slower.
-
-config DEBUG_PREEMPT
- bool "Debug preemptible kernel"
- depends on DEBUG_KERNEL && PREEMPT
- default y
- help
- If you say Y here then the kernel will use a debug variant of the
- commonly used smp_processor_id() function and will print warnings
- if kernel code uses it in a preemption-unsafe way. Also, the kernel
- will detect preemption count underflows.
-
-config DEBUG_MUTEXES
- bool "Mutex debugging, deadlock detection"
- default y
- depends on DEBUG_KERNEL
- help
- This allows mutex semantics violations and mutex related deadlocks
- (lockups) to be detected and reported automatically.
-
-config DEBUG_SPINLOCK
- bool "Spinlock debugging"
- depends on DEBUG_KERNEL
- help
- Say Y here and build SMP to catch missing spinlock initialization
- and certain other kinds of spinlock errors commonly made. This is
- best used in conjunction with the NMI watchdog so that spinlock
- deadlocks are also debuggable.
-
-config DEBUG_SPINLOCK_SLEEP
- bool "Sleep-inside-spinlock checking"
- depends on DEBUG_KERNEL
- help
- If you say Y here, various routines which may sleep will become very
- noisy if they are called with a spinlock held.
-
-config DEBUG_KOBJECT
- bool "kobject debugging"
- depends on DEBUG_KERNEL
- help
- If you say Y here, some extra kobject debugging messages will be sent
- to the syslog.
-
-config DEBUG_HIGHMEM
- bool "Highmem debugging"
- depends on DEBUG_KERNEL && HIGHMEM
- help
- This options enables addition error checking for high memory systems.
- Disable for production systems.
-
-config DEBUG_BUGVERBOSE
- bool "Verbose BUG() reporting (adds 70K)" if DEBUG_KERNEL && EMBEDDED
- depends on BUG
- depends on ARM || ARM26 || M32R || M68K || SPARC32 || SPARC64 || X86_32
|| FRV
- default !EMBEDDED
- help
- Say Y here to make BUG() panics output the file name and line number
- of the BUG call as well as the EIP and oops trace. This aids
- debugging but costs about 70-100K of memory.
-
-config DEBUG_INFO
- bool "Compile the kernel with debug info"
- depends on DEBUG_KERNEL && !X86_64_XEN
- help
- If you say Y here the resulting kernel image will include
- debugging info resulting in a larger kernel image.
- Say Y here only if you plan to debug the kernel.
-
- If unsure, say N.
-
-config DEBUG_IOREMAP
- bool "Enable ioremap() debugging"
- depends on DEBUG_KERNEL && PARISC
- help
- Enabling this option will cause the kernel to distinguish between
- ioremapped and physical addresses. It will print a backtrace (at
- most one every 10 seconds), hopefully allowing you to see which
- drivers need work. Fixing all these problems is a prerequisite
- for turning on USE_HPPA_IOREMAP. The warnings are harmless;
- the kernel has enough information to fix the broken drivers
- automatically, but we'd like to make it more efficient by not
- having to do that.
-
-config DEBUG_FS
- bool "Debug Filesystem"
- depends on DEBUG_KERNEL && SYSFS
- help
- debugfs is a virtual file system that kernel developers use to put
- debugging files into. Enable this option to be able to read and
- write to these files.
-
- If unsure, say N.
-
-config DEBUG_VM
- bool "Debug VM"
- depends on DEBUG_KERNEL
- help
- Enable this to turn on extended checks in the virtual-memory system
- that may impact performance.
-
- If unsure, say N.
-
-config FRAME_POINTER
- bool "Compile the kernel with frame pointers"
- depends on DEBUG_KERNEL && (X86 || CRIS || M68K || M68KNOMMU || FRV ||
UML)
- default y if DEBUG_INFO && UML
- help
- If you say Y here the resulting kernel image will be slightly larger
- and slower, but it might give very useful debugging information on
- some architectures or if you use external debuggers.
- If you don't debug the kernel, you can say N.
-
-config FORCED_INLINING
- bool "Force gcc to inline functions marked 'inline'"
- depends on DEBUG_KERNEL
- default y
- help
- This option determines if the kernel forces gcc to inline the
functions
- developers have marked 'inline'. Doing so takes away freedom from gcc
to
- do what it thinks is best, which is desirable for the gcc 3.x series
of
- compilers. The gcc 4.x series have a rewritten inlining algorithm and
- disabling this option will generate a smaller kernel there. Hopefully
- this algorithm is so good that allowing gcc4 to make the decision can
- become the default in the future, until then this option is there to
- test gcc for this.
-
-config RCU_TORTURE_TEST
- tristate "torture tests for RCU"
- depends on DEBUG_KERNEL
- default n
- help
- This option provides a kernel module that runs torture tests
- on the RCU infrastructure. The kernel module may be built
- after the fact on the running kernel to be tested, if desired.
-
- Say Y here if you want RCU torture tests to start automatically
- at boot time (you probably don't).
- Say M if you want the RCU torture tests to build as a module.
- Say N if you are unsure.
