+ 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=$(/bin/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
