Hi,
I can't see the entry for
vmm = xen.gz
or similar.
You need a special elilo with support for the xen hypervisor. This extended
elilo starts the image defined with vmm (the hypervior) first.
Attached is a document written by anyone from the list - please see part "Boot
Xen & Domain0" which describes this stuff.
Hope this helps!
Dietmar.
=================================
# Recipe of Booting up Xen/dom0/domU on IA64 system
# 06/02/2006 Written by Xen-ia64-devel community.
My enviroment is;
Machine : Tiger4
Domain0 OS : RHEL4 U2
DomainU OS : RHEL4 U2
----------------------------
Build xen
1. Download source
# hg clone http://xenbits.xensource.com/ext/xen-ia64-unstable.hg
2. # make world
3. # make install-tools
4. copy kernels and xen
# cp xen/xen.gz /boot/efi/efi/redhat/
# cp
linux-2.6.16.13-xen/vmlinux.gz /boot/efi/efi/redhat/vmlinuz-2.6.16.13-xen
5. make initrd for Dom0/DomU
# cd linux-2.6.16.13-xen/
# make modules_install
# mkinitrd -f /boot/efi/efi/redhat/initrd-2.6.16.13-xen.img
2.6.16.13-xen --builtin mptbase --builtin mptscsih
# cd ..
---------------------------------
Make OSimg for DomU
1. make file
# dd if=/dev/zero of=/root/rhel4.img bs=1M seek=4096 count=0
# 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)
# vi /mnt/etc/inittab
id:3:initdefault:
4. add tty0 into /etc/securetty
# vi /mnt/etc/securetty (add tty0)
5. umount
# umount /mnt
-------------------------------------
Boot Xen & Domain0
1. replace elilo
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-2.6.16.13-xen
label=xen
vmm=xen.gz
initrd=initrd-2.6.16.13-xen.img
read-only
append="com2=115200,8n1 console=com2 dom0_mem=1G -- nomca nosmp
console=tty0 console=ttyS1,115200,8n1 rhgb root=/dev/sda2"
-------------------------------------
Boot DomainU
1. make config of DomU
# vi /etc/xen/rhel4
kernel = "/boot/efi/efi/redhat/vmlinuz-2.6.16.13-xen"
ramdisk = "/boot/efi/efi/redhat/initrd-2.6.16.13-xen.img"
memory = 384
name = "rhel4"
disk = [ 'file:/root/rhel4.img,hda1,w' ]
root = "/dev/hda1 ro"
extra = "nomca console=tty0 3"
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 rhel4
