xl cd-insert / xl cd-eject on xen-unstable

[Fantu]

Someone can explain use of these commands? I ran tests with a hvm domU but
with errors

For example:
xl -v cd-insert XP hdc raw:/mnt/vm/iso/test.iso
libxl: error: libxl.c:1647:libxl_cdrom_insert: Virtual device not found

Thanks for any reply.

What is your guest configuration? You need to have created it with an
empty virtual CDROM device (specifically hdc in the case you outline
above).

Thanks for reply.
What I must write for emply virtual cdrom? I tried 'hdc,ro,cdrom' but return
parsing error.

I also tried cd-eject with this configuration:
---------------------------------------
name='XP'
builder="hvm"
memory=1024
vcpus=2
hap=1
pae=1
acpi=1
apic=1
nx=1
vif=['bridge=xenbr0']
#vfb=['vnc=1,vncunused=1,vnclisten=0.0.0.0,keymap=it']
disk=['/mnt/vm/disks/XP.disk1.xm,raw,hda,rw','/mnt/vm/iso/test.iso,raw,hdc,ro,cdrom']
#disk=['/mnt/vm/disks/XP.disk1.xm,raw,hda,rw']
boot='cd'
xen_platform_pci=1
viridian=1
device_model_version="qemu-xen"
#device_model_override="/usr/lib/xen/bin/qemu-debug.sh"
vnc=1
vncunused=1
vnclisten="0.0.0.0"
keymap="it"
#spice=1
#spicehost="0.0.0.0"
#spiceport=6000
#spicedisable_ticketing=1
on_poweroff="destroy"
on_reboot="restart"
on_crash="destroy"
stdvga=0
#device_model_args=["-vga qxl -global qxl-vga.vram_size_mb=16"]
#videoram=128
#device_model_args=["-vga qxl"]
---------------------------------------

And return this error:
xl cd-eject XP hdc
command line: config parsing error in disk specification: unknown value for
format: near `hdc:cdrom' in `,hdc:cdrom,r'

xl cd-eject is not full compatible with new disk configuration? (the cdrom
added on xl configuration file is working)

I Try also with:
disk=['/mnt/vm/disks/XP.disk1.xm,raw,hda,rw','/mnt/vm/iso/test.iso,raw,hdc:cdrom,r']
But always same error on eject:
xl cd-eject XP hdc
command line: config parsing error in disk specification: unknown value for
format: near `hdc:cdrom' in `,hdc:cdrom,r'

Seem not refer to domU configuration files but xl bug

Probably I have found the bug, on xl_cmdimpl.c on main_cd_eject function:
cd_insert(p, virtdev, NULL);
It gives error, probably not compatible with new disk configuration parsing.
I tried to modify cd_insert function but without success.
Someone can fix this bug please?
