Hi, Yongkang and all
I can boot up domU by using my special initrd without vif.
I think mkinitrd of fc6 make initrd by using dom0 infomation.
(for example dom0's /etc/fstab, dom0's pci infomaition. )
So when xm boot domU, domU kernel don't use bootparmeter of domU.
The below is a recipe of making my special inird
1. copy initrd
# mkdir tmp
# cp /boot/efi/efi/redhat/initrd-2.6.18-1.2679.fc6xenU.img tmp/
2. expand inird
# cd tmp
# gzip -cd ../initrd-2.6.18-1.2679.fc6xenU.img |cpio -id
3. modify init in initrd
# vi init
insmod /lib/ohci-hcd.ko
echo "Loading ehci-hcd.ko module"
insmod /lib/ehci-hcd.ko
mount -t usbfs /proc/bus/usb /proc/bus/usb
echo "Loading jbd.ko module"
insmod /lib/jbd.ko
echo "Loading ext3.ko module"
insmod /lib/ext3.ko
#echo "Loading scsi_mod.ko module" <<<<<< comment out
#insmod /lib/scsi_mod.ko <<<<<< comment out
#echo "Loading sd_mod.ko module" <<<<<< comment out
#insmod /lib/sd_mod.ko <<<<<< comment out
#echo "Loading scsi_transport_spi.ko module" <<<<<< comment out
#insmod /lib/scsi_transport_spi.ko <<<<<< comment out
#echo "Loading mptbase.ko module" <<<<<< comment out
#insmod /lib/mptbase.ko <<<<<< comment out
#echo "Loading mptscsih.ko module" <<<<<< comment out
#insmod /lib/mptscsih.ko <<<<<< comment out
#echo "Loading mptspi.ko module" <<<<<< comment out
#insmod /lib/mptspi.ko <<<<<< comment out
echo "Loading xenblk.ko module"
insmod /lib/xenblk.ko
mkblkdevs
#resume LABEL=SWAP-sda3 <<<<<< comment out
echo Creating root device.
mkrootdev -t ext3 -o defaults,ro sda1 <<<<change device to sda1
echo Mounting root filesystem.
mount /sysroot
echo Setting up other filesystems.
setuproot
echo Switching to new root and running init.
switchroot
4. make new initrd
# find . -print | cpio --quiet -c -o | gzip -9 >../initrd-new.img
5. my domU configuration
kernel = "/boot/efi/efi/redhat/vmlinuz-2.6.18-1.2679.fc6xen"
ramdisk = "/xen/initrd-new.img"
memory = 1024
name = "fc6.DomU"
#vif = [ '' ]
disk = [ 'file:/xen/image/fc6.root.img,sda1,w' ]
root = "/dev/sda1 ro"
extra = "4 ide0=noprobe ide1=noprobe ide2=noprobe ide3=noprobe selinux=0
rhgb"
6. etc
6.1. copy modlues into domU image file
# mount -o loop domU.img /mnt
# cp -a /lib/modules/2.6.18-1.2679.fc6xen/ /mnt/lib/modules/
6.2. disable selinux
# vi /etc/sysconfig/selinux
SELINUX=disabled <<<< change enforcing to disabled
6.3. modify /etc/fstab in domU.img
/dev/sda1 / ext3 defaults 1 1
devpts /dev/pts devpts gid=5,mode=620 0 0
tmpfs /dev/shm tmpfs defaults 0 0
proc /proc proc defaults 0 0
sysfs /sys sysfs defaults 0 0
But I cannot use network on domU.
I'll check the src.rpm of kernel-xen.

Akio Takebe
