I found a solution:

#+begin_src
    OS=[ARCH="x86_64",BOOT="hd"]
    RAW=[DATA="
            <os>
                    <boot dev='cdrom'/>
            </os>
    ",TYPE="kvm"]
#+end_src

This result in the following xml:

#+begin_src
<domain type='kvm' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'>
        <name>one-20</name>
        <cputune>
                <shares>512</shares>
        </cputune>
        <memory>1048576</memory>
        <os>
                <type arch='x86_64'>hvm</type>
                <boot dev='hd'/>
        </os>
        <devices>
                <emulator>/usr/bin/kvm</emulator>
                <disk type='file' device='disk'>
                        <source file='/var/lib/one//datastores/100/20/disk.0'/>
                        <target dev='vda'/>
                        <driver name='qemu' type='qcow2' cache='default'/>
                </disk>
                <disk type='file' device='cdrom'>
                        <source file='/var/lib/one//datastores/100/20/disk.1'/>
                        <target dev='hda'/>
                        <readonly/>
                        <driver name='qemu' type='raw' cache='default'/>
                </disk>
                <disk type='file' device='cdrom'>
                        <source file='/var/lib/one//datastores/100/20/disk.2'/>
                        <target dev='hdb'/>
                        <readonly/>
                        <driver name='qemu' type='raw'/>
                </disk>
                <interface type='bridge'>
                        <source bridge='vswitch'/>
                        <virtualport type='openvswitch'/>
                        <mac address='02:00:ac:10:2a:65'/>
                        <model type='virtio'/>
                </interface>
                <graphics type='vnc' listen='0.0.0.0' port='5920' keymap='fr'/>
                <input type='tablet' bus='usb'/>
        </devices>
        <features>
                <acpi/>
        </features>

        <os>
                <boot dev='cdrom'/>
        </os>

</domain>
#+end_src

In that case the VM try to boot on hard drive first and then CDROM.

Regards.
