how to use cdrom drive in Xen? thanks

Too little info.
Assuming the CD lists that it will run only on Windows, you should install Wine first and then run the CD.

I mean I always use the iso file for Xen,I want use physics cdrom,how to doing this? thanks

A bit more infor about "physics cdrom" will help people to help you better.
Is it a course/tutorial CD like the CBT Nuggets/Tesout CDs or is it the cdrom drive brand or what ? Elabotrate.

sorry all,I mean "physics cdrom" is cdrom drive.just is real cdrom drive,not is virtual cdrom.

I take it you meant "physical drive" ,in any case.
As you didnt state : wether the drive is attached to the PC or what steps you have taken so far and errors it throws I will assume its attched to your computer and you just want to be able to read it. in which case just insert a cd into the drive , open a terminal and type:

mount /dev/cdrom /media/cdrom

if that doesnt work (only if above fails)

mkdir /media/cdromdrive
mount /dev/cdrom /media/cdromdrive

you have to be root for all these commands to work.if it doesnt work post all errors you get.

Hi, I am a newbie and is looking for solution to use cd-rom under redhat
Xen (virtual machine of windows 2003, I only can see the qemu cd rom but can't use it), I found one solution as Installing and using a fully-virtualized Xen guest,

Using a real CD-ROM drive

You can also use a real CD-ROM drive in the virtual guest. Use the following device entry for the guest CD-ROM drive, changing the source option to list the device name of the CD-ROM drive to be used:

<disk type='block' device='cdrom'>
<driver name='phy'/>
<source dev='/dev/hdc'/>
<target dev='hdc'/>
<readonly/>
</disk>

It looks like I should modify a file when the linux boots

HOW

should put one cd media in your drive and restart the virtual op ( in my case is windows) and the windows can find the disk, working fine. but if you want to change the media, it will have problem. I have seen reject the media first and then put one back, I will google it later

Was trying long and hard to figure out how to present CD/DVD media to the paravirtualized host. Worked like a charm for me! Hope it helps!
