# mkdir-p/mnt/secondary
# mount-t NFS 172.16.204.111:/export/secondary/mnt/secondary/
2), download SYSTEMVM file
3), unzip the SYSTEMVM file
#/usr/lib64/cloud/agent/scripts/storage/secondary/cloud-install-sys-tmplt-m/mnt/secondary-f systemvm.vhd.bz2-h Xenserver-f
4), after completion, uninstall level two storage
#umount/mnt/secondary/
