It ins't working too. Below, I'm reproducing informations about my test system: My xen version: # xm info | grep -E 'major|minor' xen_major : 3 xen_minor : 3 # virtual machine dmesg | Registering block device major 202 | xvda: xvda1 xvda2 xvda3 | Registering block device major 22 | hdc: unknown partition table In vm configuration, the variable 'disk' is set like below: | disk = [ 'phy:/dev/empirevg/centos,xvda,w', 'file:/home/iso/centos-xen-image/CentOS-5.2-x86_64-bin-1of7.iso,hdc:cdrom,r' ] In log has only these entries about the vbd: # /var/log/xen/qemu-dm-pvcentos.log | medium change watch on `hdc' (index: 1): /home/iso/centos-xen-image/CentOS-5.2-x86_64-bin-1of7.iso # /var/log/xen/xend.log | [2008-09-26 13:55:00 3997] TRACE (XendDomainInfo:2860) XendDomainInfo.update done on domain 152: {'vcpus_params': {'cap': 0, 'weight': 256}, 'PV_args': '', '_temp_kernel': '/var/run/xend/boot/boot_kernel.aKv9gR', 'features': '', '_temp_args': 'ro root=LABEL=/ rhgb quiet', 'cpus': [[], []], 'paused': 1, 'shutdown_reason': 0, 'actions_after_reboot': 'restart', 'vcpu_avail': 3, 'VCPUs_live': 1, 'PV_bootloader': '', 'actions_after_crash': 'restart', 'vbd_refs': ['96741415-cc7f-888f-bb22-d9536e4a2667', 'c4cb92df-3d4e-a8b1-429d-e291aed95248'], 'PV_ramdisk': '', 'memory_dynamic_min': 268435456, '_temp_ramdisk': '/var/run/xend/boot/boot_ramdisk.2Dkcev', 'name_label': 'pvcentos', 'VCPUs_at_startup': 1, 'HVM_boot_params': {}, 'platform': {'device_model': '/usr/lib64/xen/bin/qemu-dm'}, 'PV_kernel': '', 'console_refs': ['f44f980b-2fee-d156-8e1a-2dcdd56c0d1a', 'c8a40489-9b26-94e2-2590-507038155e2e'], 'shutdown': 0, 'dying': 0, '_temp_using_bootloader': '1', 'blocked': 0, 'on_xend_stop': 'ignore', 'memory_static_min': 0, 'HVM_boot_policy': '', 'domid': 152, 'VCPUs_max': 2, 'start_time': 1222448100.201066, 'online_vcpus': 1, 'memory_static_max': 268435456, 'actions_after_shutdown': 'destroy', 'on_xend_start': 'ignore', 'crashed': 0, 'memory_dynamic_max': 268435456, 'actions_after_suspend': '', 'is_a_template': False, 'is_control_domain': False, 'uuid': 'b7f2a041-0369-a085-c4de-49073e338742', 'cpu_time': 0.0, 'shadow_memory': 0, 'target': 0, 'PV_bootloader_args': '', 'notes': {'FEATURES': writable_page_tables|writable_descriptor_tables|auto_translated_physmap|pae_pgdir_above_4gb|supervisor_mode_kernel', 'VIRT_BASE': 18446744071562067968L, 'GUEST_VERSION': '2.6', 'PADDR_OFFSET': 18446744071562067968L, 'GUEST_OS': 'linux', 'HYPERCALL_PAGE': 18446744071564189696L, 'LOADER': 'generic', 'ENTRY': 18446744071564165120L, 'XEN_VERSION': 'xen-3.0'}, 'other_config': {}, 'running': 0, 'devices': {'96741415-cc7f-888f-bb22-d9536e4a2667': ('vbd', {'uuid': '96741415-cc7f-888f-bb22-d9536e4a2667', 'bootable': 1, 'devid': 51712, 'driver': 'paravirtualised', 'dev': 'xvda', 'uname': 'phy:/dev/empirevg/centos', 'mode': 'w'}), 'a5ecf6ea-a8b1-67d1-6308-068cebf5ab80': ('vkbd', {'devid': 0, 'uuid': 'a5ecf6ea-a8b1-67d1-6308-068cebf5ab80'}), 'f44f980b-2fee-d156-8e1a-2dcdd56c0d1a': ('vfb', {'other_config': {'type': 'vnc', 'xauthority': '/root/.Xauthority'}, 'xauthority': '/root/.Xauthority', 'devid': 0, 'location': 'localhost:5901', 'type': 'vnc', 'uuid': 'f44f980b-2fee-d156-8e1a-2dcdd56c0d1a'}), 'c8a40489-9b26-94e2-2590-507038155e2e': ('console', {'other_config': {}, 'protocol': 'vt100', 'uuid': 'c8a40489-9b26-94e2-2590-507038155e2e', 'location': '2'}), 'c4cb92df-3d4e-a8b1-429d-e291aed95248': ('vbd', {'uuid': 'c4cb92df-3d4e-a8b1-429d-e291aed95248', 'bootable': 0, 'devid': 5632, 'driver': 'paravirtualised', 'dev': 'hdc:cdrom', 'uname': 'file:/home/iso/centos-xen-image/CentOS-5.2-x86_64-bin-1of7.iso', 'mode': 'r'}), '256dc778-ec84-f42b-f31b-229fc88544d6': ('vif', {'bridge': 'eth0', 'mac': '00:16:3e:3f:d6:38', 'devid': 0, 'uuid': '256dc778-ec84-f42b-f31b-229fc88544d6'})}, 'vif_refs': ['256dc778-ec84-f42b-f31b-229fc88544d6'], 'vtpm_refs': []} Perhaps, only HVM supports cdrom media type. PVM has no this feature or I can be wrong.
