I try to use cdrom in domU linux pv, on Lucid and Natty with
'phy:/dev/scd0,xvdc,r' see it as internal disk (not cdrom) and only
administrators can mount it, i try also 'phy:/dev/scd0,xvdc1,r' but not
work.
On Oneiric and Precise (daily build) with 'phy:/dev/scd0,xvdc,r' see it as
cdrom but not automount it, work only manual mount of xvdc; i try also
'phy:/dev/scd0,xvdc1,r' but not work.
Is possible use cdrom on linux domU pv full working where also normal user
can mount it without terminal?
I do something wrong, or there are still bugs in this regard?
Thanks for any reply.

You don't say which toolstack you are using but if you consult
http://xenbits.xen.org/docs/unstable/misc/xl-disk-configuration.txt you
will see that you need to explicitly mark a device as a CDROM.

Thanks for reply and sorry for my mistake on write here, in the configuration
I have do right with :cdrom ('phy:/dev/scd0,xvdc:cdrom,r'), i have also
report this problem time ago without reply:
http://xen.1045712.n5.nabble.com/Cdrom-not-working-on-Lucid-domU-td4586693.html
The toolstack use now is always xm, and test i write in first message is all
with :cdrom.
I have also one question about xl, probably soon I begin to test xen 4.2
from unstable with toolstack xl, I see on xl configuration link disk format
support raw, qcow, qcow2, vhd with deprecated prefix (tap2...) ignored.
The blktap continue to be used automatically based on format choise and if
not present use "file" or it will not need additional modules?

I tried to use cdrom in domU linux pv (Linux Mint 11 based on Natty).
With '/mnt/vm/iso/test.iso,raw,xvdb,ro,cdrom', Mint sees it as internal disk
(not cdrom) and only administrators can mount it.
I tried also '/dev/scd0,raw,xvdb,ro,cdrom' does the same thing.
Is possible use cdrom on linux domU pv full working where also normal user
can mount it without terminal?
Did I something wrong, or are there still bugs in this regard?
Dom0 is Squeeze 6.0.4 64 bit with kernel 2.6.32-5-xen-amd64 version
2.6.32-41, xen from xen-unstable.hg changeset 24593:e2722b24dc09
DomU xl file configuration:
-------------------------
name='MINT11PV'
memory=1024
vcpus=2
disk=['/mnt/vm/disks/MINT11PV.disk1.xm,raw,xvda1,rw',
'/mnt/vm/iso/test.iso,raw,xvdb,ro,cdrom']

Thanks for any reply and sorry for bad english.

I updated xen to changeset 24701:3574f4d67843 and also tried with xl
cd-insert and it failed with this error:
xl cd-insert MINT12PV xvdb raw:/dev/scd0
libxl: error: libxl.c:1579:libxl_cdrom_insert: Virtual device not found
I used wrong parameters or is there a bug?
Thanks for any reply.

cd-insert is an HVM guest command, it must refer to an existing emulated
CD-ROM device. Since you say you are using PV this can't exist.
The error message could probably be improved here.

It should be. Please can you provide the output of "xenstore-ls -fp"
when the guest is running with the device attached.
Also from within the guest can you run (as root):
udevadm info --query=all --path /block/xvdb
and post the output.

The most recent bugs of this type were in udev and not Xen and caused it
to fail to correctly detect Xen CD-ROMs as such. If the above indicates
everything is OK on the Xen side then we can delve into that a little
deeper but in the meantime what version of udev are you running in the
guest?

What is the domU kernel version?
Ian.

Thanks but I also need to see the xenstore-ls -fp corresponding to each
case. For simplicity lets just concentrate on the
"/mnt/vm/iso/precise.iso,raw,xvdb,ro,cdrom" case for now. Once we have
solved that we can revisit any others which are still broken.
The issue is, I suspect, related to the lack of ID_CDROM=1 in most of
your outputs. Running "/lib/udev/cdrom_id $DEV" ought to produce some
related output, if not please can you use strace to observe the ioctls
it is making (and post the log).
I suspect this is more likely to be a udev issue with Linux Mint /
Ubuntu. Have you searched the appropriate bug trackers / wikis / etc for
those distros?
Ian.

Soon I'll try again next version of Ubuntu now in alpha status (12.04 LTS)
and if the problem about cdrom is of distribution I will report it on
launchpad, I had already searched the forums and launchpad about it without
getting resolved.

I wonder if this kernel is missing:
commit 4352b47ab7918108b389a48d2163c9a4c2aaf139
Author: Marek Marczykowski <marmarek@mimuw.edu.pl>
Date: Tue May 3 12:04:52 2011 -0400
xen-blkfront: fix data size for xenbus_gather in blkfront_connect
barrier variable is int, not long. This overflow caused another variable
override: "err" (in PV code) and "binfo" (in xenlinux code -
drivers/xen/blkfront/blkfront.c). The later caused incorrect device
flags (RO/removable etc).

The symptoms of this could include a device not appearing as a cdrom
when it should. Your xenstore output contains
/local/domain/0/backend/vbd/1/51728/device-type = "cdrom"
(n0,r1)
but the CDROM_GET_CAPABILITY ioctl is failing which is somewhat
consistent with this.
