[Xen-ia64-devel] [FYI] Recipe of build and boot of Xen/IA64

[Akio Takebe <takebe_akio@xxxxxxxxxxxxxx>]

Hi,

We can boot RHEL4 domU without initrd.
I have written the recipe.
(Thank you for many advice, everyone :-))

My enviroment is;
  Machine  : Tiger4
  Dom0 OS  : RHEL4 U2
  DomU OS  : RHEL4 U2
  changeset: 8241:0255f48b757f

----------------------------
Build xen
 1. Download source
    # hg clone http://xenbits.xensource.com/ext/xen-ia64-unstable.hg

 2. # make world -j4
    
 3. make menuconfig in Dom0
    # cd linux-2.6.12-xen0
    # make menuconfig
        CONFIG_IA64_DIG=y
    # cd ..

 4. make menuconfig in DomU
    # cd linux-2.6.12-xenU
    # make menuconfig 
        CONFIG_IA64_DIG=y
        # CONFIG_EFI_RTC is not set
    # cd ..

 5. # make kernels -j4

 6. # make uninstall

 7. # make install-tools

 8. copy kernels and xen
    # cp xen/xen.gz /boot/efi/efi/xen/
    # cp linux-2.6.12-xen0/vmlinux.gz /boot/efi/efi/xen/vmlinuz-2.6.12-xen0
    # cp linux-2.6.12-xenU/vmlinux.gz /boot/vmlinux-2.6.12-xenU

 9. make initrd for Dom0
    # cd linux-2.6.12-xen0/
    # make modules_install
    # mkinitrd -f /boot/efi/efi/xen/initrd-2.6.12-xen0.img 2.6.12.6-xen0 
--builtin mptbase --builtin mptscsih
    # cd ..

---------------------------------
Make OSimg for DomU
 1. make file
    # dd if=/dev/zero of=/root/rhel4.img bs=1M count=4096
    # mke2fs -F -j /root/rhel4.img
    # mount -o loop /root/rhel4.img /mnt
    # cp -ax /{dev,var,etc,usr,bin,sbin,lib} /mnt
    # mkdir /mnt/{root,proc,sys,home,tmp}

 2. modify DomU's fstab
    # vi /mnt/etc/fstab 
       /dev/hda1   /            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 (runlevel and tty)
    # vi /mnt/etc/inittab
       id:3:initdefault:
    # Run gettys in standard runlevels
    1:2345:respawn:/sbin/mingetty tty0
    #1:2345:respawn:/sbin/mingetty tty1
    #2:2345:respawn:/sbin/mingetty tty2
    #3:2345:respawn:/sbin/mingetty tty3
    #4:2345:respawn:/sbin/mingetty tty4
    #5:2345:respawn:/sbin/mingetty tty5
    #6:2345:respawn:/sbin/mingetty tty6
    
 4. add tty0 into /etc/securetty
    # vi /mnt/etc/securetty (add tty0)
 
 5. umount
    # umount /mnt
    
-------------------------------------
Boot Xen
 1. replace elilo
    download from the below
    http://elilo.sourceforge.net/cgi-bin/blosxom
    
 2. modify elilo.conf
     prompt
     timeout=20
     default=xen
     relocatable
     
     image=vmlinuz-2.6.12-xen0
             label=xen
             vmm=xen-.gz
             initrd=initrd-2.6.12-xen0.img
             read-only
             append="com2=115200,8n1 console=com2 sched=bvt tbuf_size=128 -- 
nomca nosmp console=tty0 console=ttyS1,115200,8n1 rhgb root=/dev/sda2"
     image=vmlinuz-2.6.9-22.EL
             label=linux
             initrd=initrd-2.6.9-22.EL.img
             read-only
             append="rhgb root=/dev/sda2"
 3. make config of DomU
   # vi /etc/xen/rhel4
     kernel = "/boot/vmlinux-2.6.12-xenU"
     memory = 384
     name = "rhel4"
     nics=0
     disk = [ 'file:/root/rhel4.img,hda1,w' ]
     root = "/dev/hda1 ro"
     extra = "3"
 
 4. After boot xen and dom0, start xend
   # /etc/init.d/xend start
   ( In the debugging case, # XEND_DEBUG=1 xend trace_start )
   
 5. start domU
   # xm create -c rhel4
 
Best Regards,

Akio Takebe
