Mauro Carvalho Chehab db9a0975a2 docs: ia64: convert to ReST
Rename the ia64 documentation files to ReST, add an
index for them and adjust in order to produce a nice html
output via the Sphinx build system.

There are two upper case file names. Rename them to
lower case, as we're working to avoid upper case file
names at Documentation.

At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

Recipe for getting/building/running Xen/ia64 with pv_ops
********************************************************
This recipe describes how to get xen-ia64 source and build it,
and run domU with pv_ops.
Requirements
============
- python
- mercurial
it (aka "hg") is an open-source source code
management software. See the below.
http://www.selenic.com/mercurial/wiki/
- git
- bridge-utils
Getting and Building Xen and Dom0
=================================
My environment is:
- Machine : Tiger4
- Domain0 OS : RHEL5
- DomainU OS : RHEL5
1. Download source::
# hg clone http://xenbits.xensource.com/ext/ia64/xen-unstable.hg
# cd xen-unstable.hg
# hg clone http://xenbits.xensource.com/ext/ia64/linux-2.6.18-xen.hg
2. # make world
3. # make install-tools
4. copy kernels and xen::
# cp xen/xen.gz /boot/efi/efi/redhat/
# cp build-linux-2.6.18-xen_ia64/vmlinux.gz \
/boot/efi/efi/redhat/vmlinuz-2.6.18.8-xen
5. make initrd for Dom0/DomU::
# make -C linux-2.6.18-xen.hg ARCH=ia64 modules_install \
O=$(pwd)/build-linux-2.6.18-xen_ia64
# mkinitrd -f /boot/efi/efi/redhat/initrd-2.6.18.8-xen.img \
2.6.18.8-xen --builtin mptspi --builtin mptbase \
--builtin mptscsih --builtin uhci-hcd --builtin ohci-hcd \
--builtin ehci-hcd
Making a disk image for guest OS
================================
1. make file::
# dd if=/dev/zero of=/root/rhel5.img bs=1M seek=4096 count=0
# mke2fs -F -j /root/rhel5.img
# mount -o loop /root/rhel5.img /mnt
# cp -ax /{dev,var,etc,usr,bin,sbin,lib} /mnt
# mkdir /mnt/{root,proc,sys,home,tmp}
Note: You may miss some device files. If so, please create them
with mknod. Or you can use tar instead of cp.
2. modify DomU's fstab::
# vi /mnt/etc/fstab
/dev/xvda1 / ext3 defaults 1 1
none /dev/pts devpts gid=5,mode=620 0 0
none /dev/shm tmpfs defaults 0 0
none /proc proc defaults 0 0
none /sys sysfs defaults 0 0
3. modify inittab
set runlevel to 3 to avoid X trying to start::
# vi /mnt/etc/inittab
id:3:initdefault:
Start a getty on the hvc0 console::
X0:2345:respawn:/sbin/mingetty hvc0
tty1-6 mingetty can be commented out
4. add hvc0 into /etc/securetty::
# vi /mnt/etc/securetty (add hvc0)
5. umount::
# umount /mnt
FYI, virt-manager can also make a disk image for guest OS.
It's GUI tools and easy to make it.
Boot Xen & Domain0
==================
1. replace elilo
elilo of RHEL5 can boot Xen and Dom0.
If you use old elilo (e.g RHEL4), please download from the below
http://elilo.sourceforge.net/cgi-bin/blosxom
and copy into /boot/efi/efi/redhat/::
# cp elilo-3.6-ia64.efi /boot/efi/efi/redhat/elilo.efi
2. modify elilo.conf (like the below)::
# vi /boot/efi/efi/redhat/elilo.conf
prompt
timeout=20
default=xen
relocatable
image=vmlinuz-2.6.18.8-xen
label=xen
vmm=xen.gz
initrd=initrd-2.6.18.8-xen.img
read-only
append=" -- rhgb root=/dev/sda2"
The append options before "--" are for xen hypervisor,
the options after "--" are for dom0.
FYI, your machine may need console options like
"com1=19200,8n1 console=vga,com1". For example,
append="com1=19200,8n1 console=vga,com1 -- rhgb console=tty0 \
console=ttyS0 root=/dev/sda2"
Getting and Building domU with pv_ops
=====================================
1. get pv_ops tree::
# git clone http://people.valinux.co.jp/~yamahata/xen-ia64/linux-2.6-xen-ia64.git/
2. git branch (if necessary)::
# cd linux-2.6-xen-ia64/
# git checkout -b your_branch origin/xen-ia64-domu-minimal-2008may19
Note:
The current branch is xen-ia64-domu-minimal-2008may19.
But you would find the new branch. You can see with
"git branch -r" to get the branch lists.
http://people.valinux.co.jp/~yamahata/xen-ia64/for_eagl/linux-2.6-ia64-pv-ops.git/
is also available.
The tree is based on
git://git.kernel.org/pub/scm/linux/kernel/git/aegl/linux-2.6 test)
3. copy .config for pv_ops of domU::
# cp arch/ia64/configs/xen_domu_wip_defconfig .config
4. make kernel with pv_ops::
# make oldconfig
# make
5. install the kernel and initrd::
# cp vmlinux.gz /boot/efi/efi/redhat/vmlinuz-2.6-pv_ops-xenU
# make modules_install
# mkinitrd -f /boot/efi/efi/redhat/initrd-2.6-pv_ops-xenU.img \
2.6.26-rc3xen-ia64-08941-g1b12161 --builtin mptspi \
--builtin mptbase --builtin mptscsih --builtin uhci-hcd \
--builtin ohci-hcd --builtin ehci-hcd
Boot DomainU with pv_ops
========================
1. make config of DomU::
# vi /etc/xen/rhel5
kernel = "/boot/efi/efi/redhat/vmlinuz-2.6-pv_ops-xenU"
ramdisk = "/boot/efi/efi/redhat/initrd-2.6-pv_ops-xenU.img"
vcpus = 1
memory = 512
name = "rhel5"
disk = [ 'file:/root/rhel5.img,xvda1,w' ]
root = "/dev/xvda1 ro"
extra= "rhgb console=hvc0"
2. After boot xen and dom0, start xend::
# /etc/init.d/xend start
( In the debugging case, `# XEND_DEBUG=1 xend trace_start` )
3. start domU::
# xm create -c rhel5
