Nevermind, just found it. Uploaded the acton-systemvm-02061012.vhd.bz2 file to the /tmp folder in the management server, then use the following command:
/usr/lib64/common/scripts/storage/secondary/cloud-install-sys-tmplt -m /mnt/secondary -f /tmp/acton-systemvm-02062012.vhd.bz2 -h xenserver -F The trick was to use -f /path/to/file instead of -h URL.to.file Kind Regards, Joaquín Angel Alonso Alvarez
