 Hi,
you made a small error in your disk configuration:
disk = [ 'phy:/dev/scd0,*hdc:*cdrom,w' ]

You have to specify hdc (or anything similar) to set the position of the cdrom drive (in this case: secondary IDE, master). It is also possible to specify e.g. sda:cdrom, which will attach the device to the first SCSI port (but you can't boot from SCSI devices).

In addition, I think it was rather /dev/scd0 instead of /dev/sd0.
I hope this helps you.

Hi,
how do I attach a cdrom to a pv guest?
Xen-server is openSuSE-11.2 and domU is opensuse-11.2.
According to the xen-manual I tried
disk = [ 'phy:/dev/sd0,cdrom,w' ]
in the vm configuration.

When creating the vm however it crashes w/o a message in /var/log/qemu-dm-opensuse11.log

I've also tried to attach with
xm block-attach opensuse11 phy:/dev/sr0 /dev/cdrom r
same problem as obove.

Thanks Felix, I proceeded as you suggested, however still the same problem.
vm config sections:
disk=[ 'file:/var/lib/xen/images/MAGRO1V/disk0,xvda,w'
 ,'phy:/dev/sr0,hdc:cdrom,r'
 ]
running 'xm create ...' I get
...

[ 2.267952] invalid opcode: 0000 [#1] SMP
[ 2.267952] last sysfs file:

...
etc.etc
