[Xen-ia64-devel] Build & Boot Dom0 for Tiger4 system

["Yang, Fred" <fred.yang@xxxxxxxxx>]

Know-How to Build & boot Domain0 on a same Tiger4 system 

1. Requirements - 
     a. Tiger4 system with Disk size more than 40GB, better to have 60GB

     b. IA64 Linux RHEL4 Update2 
     c. Perform all the following operations in SuperVisor mode 

2. Preparing target tiger4 system 
    a. Install "complete" RHEL4U2 disk by "customize install"
"everything" 
    b. Check to have SDL installed
         > rpm -q -a | grep SDL 
            SDL-1.2.7-8 SDL-devel-1.2.7-8 

3. Download and install mercurial HG tool from 
      http://www.selenic.com/mercurial/wiki/index.cgi/UnixInstall 
      >tar xvzf mercurial-0.7.tar.gz 
      >cd mercurial-0.7 
      >python setup.py install 
   Note: XenBuild.sh (Xen building) depends mercurial-0.7 version c. 

4. Download and Build Xen 
     goto your prefer local directory To build 
     Modify XenBuild.sh to reflect your local proxy server 
                  export http_proxy=http://proxy.xxx.yyy.com:911 
     > XenBuild.sh or XenBuild.sh Cset# (XenBuild.sh see end of the
mail)

5. Add elilo Xen entry 
    Add following config to end of /boot/efi/efi/redhat/elilo.conf 
         image=vmlinux-2.6-xen0.gz 
                      label=xen 
                      vmm=xen.gz 
                      initrd=initrd-2.6-xen0.img 
                      read-only 
                      append="com2=57600,8n1 console=com2 sched=bvt --
nomca console=tty0 console=ttyS1,57600 root=/dev/sda3" 
                                          (root=/dev/sda3 should match
with local disk with "mount" command) 

6. Copy Xen-enabled elilo.conf 
     > cp ~/XenTree/xen/arch/ia64/tools/xelilo/xlilo.efi
/boot/efi/efi/redhat/elilo.efi 
             or you can keep the original elilo.efi for legacy Linux
boot and use "xlilo xen" for Xen boot only 

7. Domain0 Boot
              EFI Shell> cd efi\redhat 
              EFI Shell> xlilo xen
