I've redone it with the XP really started :

768 = ""
 domain = "xp01"
 frontend = "/local/domain/18/device/vbd/768"
 uuid = "35d3f4d3-e627-6e8c-4f12-3e2ea261da37"
 dev = "hda"
 state = "4"
 params = "/dev/vg02/xp01"
 mode = "w"
 online = "1"
 frontend-id = "18"
 type = "phy"
 physical-device = "fd:b"
 hotplug-status = "connected"
 feature-barrier = "1"
 sectors = "31457280"
 info = "0"
 sector-size = "512"
5632 = ""
 domain = "xp01"
 frontend = "/local/domain/18/device/vbd/5632"
 uuid = "64613276-803e-7d2c-9595-03ba5232d771"
 dev = "hdc"
 state = "4"
 params = "/dev/vg01/xp01-data"
 mode = "w"
 online = "1"
 frontend-id = "18"
 type = "phy"
 physical-device = "fd:e"
 hotplug-status = "connected"
 feature-barrier = "1"
 sectors = "104857600"
 info = "0"
 sector-size = "512"
5696 = ""
 domain = "xp01"
 frontend = "/local/domain/18/device/vbd/5696"
 uuid = "18ec5077-0027-07ca-85ed-c7f716cf8627"
 dev = "hdd"
 state = "2"
 params = "/dev/hdb"
 mode = "r"
 online = "1"
 frontend-id = "18"
 type = "phy"
 physical-device = "3:40"
 hotplug-status = "connected"

And with /nogplpv (In this case the cdrom is show in XP):

768 = ""
 domain = "xp01"
 frontend = "/local/domain/19/device/vbd/768"
 uuid = "e3fc3bb5-570d-a049-89a8-79e4e653a4af"
 dev = "hda"
 state = "4"
 params = "/dev/vg02/xp01"
 mode = "w"
 online = "1"
 frontend-id = "19"
 type = "phy"
 physical-device = "fd:b"
 hotplug-status = "connected"
 feature-barrier = "1"
 sectors = "31457280"
 info = "0"
 sector-size = "512"
5632 = ""
 domain = "xp01"
 frontend = "/local/domain/19/device/vbd/5632"
 uuid = "38ad5b51-5ec8-d9ba-ace6-7cd5a4ba6200"
 dev = "hdc"
 state = "4"
 params = "/dev/vg01/xp01-data"
 mode = "w"
 online = "1"
 frontend-id = "19"
 type = "phy"
 physical-device = "fd:e"
 hotplug-status = "connected"
 feature-barrier = "1"
 sectors = "104857600"
 info = "0"
 sector-size = "512"
5696 = ""
 domain = "xp01"
 frontend = "/local/domain/19/device/vbd/5696"
 uuid = "2dff6e16-2099-09d4-b302-4ebf9ab7f18c"
 dev = "hdd"
 state = "2"
 params = "/dev/hdb"
 mode = "r"
 online = "1"
 frontend-id = "19"
 type = "phy"
 physical-device = "3:40"
 hotplug-status = "connected"
