Sorry for the duplicated email Congyang, I forgot to repli= ed all:

Hi Congyang,

Thank you for the hint, after building xen, your script works for qemu-x= en!

so now I am trying to set up the secondary node with the script pro= vided by Changlong in his first reply:
--------------------------------------------------------------------------= ---------------------
rm -f /var/log/xen/*
rm -f /var/lib/xen= /userdata-d.*

tmp_disk_size=3D`./qemu-c= olo/qemu-img info $local_img |grep = 'virtual size' |awk=C2=A0 '{print $3}'`
rm -rf /mnt/ramfs/*
umount /m= nt/ramfs/
rm -rf /mnt/ramfs/
mkdir /mnt/ramfs
function create_image()
{
=C2=A0 =C2=A0 /root/xie/xen/= tools/qemu-xen-dir/qemu-img create = -f qcow2 $1 $tmp_disk_size
}
function prepare_temp_images()
{
=C2=A0 =C2=A0 grep -q "^none= /mnt/ramfs ramfs" /proc/mounts

=C2=A0 =C2=A0 =C2=A0 =C2=A0 mount= -t ramfs none /mnt/ramfs/ -o size=3D2G
=C2=A0 =C2=A0 fi

=C2=A0 =C2=A0 if [[ ! -e $active_disk ]]; then
=C2=A0 =C2=A0 =C2=A0 =C2=A0 cr= eate_image $active_disk

=C2=A0 =C2=A0 =C2=A0 =C2=A0 create_image $hidd= en_disk
=C2=A0 =C2=A0 fi
}
---= ---------------------------------------------------------------------------= -----------------

I have question about for the codes below:
<= div style=3D"font-size:12.8px">
active_disk=3D/mnt/ramfs/active_disk.img
hidden_disk=3D/mnt/ramfs/hidden_<= span style=3D"font-size:12.8px">disk.img
local_img=3D/root/xie/suse-64hvm= .img

Do I have to creat= e my own image and put the img in that location? if so what kind of img spe= cifically?=C2=A0

because when I look into /mnt/ramfs, it is an empty d= irectory.

Thank you!

Do you build xen before?
