What are you trying to do? Do you need to attach/detach a cdrom often? If it is to install the OS, you should either try a vendor shipped image or create a custom one, save it and push it to your OpenStack deployment.</div>
</div>
<div><div class="gmail_default" style="font-family:georgia,serif;display:inline">See here: </div><a href="http://docs.openstack.org/trunk/openstack-compute/admin/content/starting-images.html" target="_blank"><div class="gmail_default" style="font-family:georgia,serif;display:inline">

To do this you could follow these steps:</div>
</div><div><div class="gmail_default" style="font-family:georgia,serif;display:inline">- launch an instance with an ephemeral/local disk large enough to hold your .iso / cdrom contents (should not be hard)</div></div><div>
<div class="gmail_default" style="font-family:georgia,serif;display:inline">- make your cdrom</div><span style="font-family:georgia,serif"> contents an .iso file: pop your <div class="gmail_default" style="font-family:georgia,serif;display:inline">
CD</div> in a cdrom on a Linu<div class="gmail_default" style="display:inline">x or U</div>nix based machine and do:</span></div><div><div class="gmail_default" style="font-family:georgia,serif;display:inline"> $ dd if=/dev/cdrom of=/path/to/mycdrom-contents.iso (assuming /dev/cdrom is a symlink pointing to your cd player device)</div>
</div><div><div class="gmail_default" style="font-family:georgia,serif;display:inline">- upload the resulting file using scp to your instance:</div></div><div><div class="gmail_default" style="font-family:georgia,serif;display:inline">
$ scp /path/to/</div><span style="font-family:georgia,serif">mycdrom-contents.iso<div class="gmail_default" style="font-family:georgia,serif;display:inline"> -i myseckey.pem <username>@XXX.XXX.XXX.XXX:~</div>
</span></div><div><span style="font-family:georgia,serif"><div class="gmail_default" style="font-family:georgia,serif;display:inline">- create a new block volume of the size of your CD contents (a little bit over will not hurt) and name it something related to your CD content.</div>
</span></div><div><span style="font-family:georgia,serif"><div class="gmail_default" style="font-family:georgia,serif;display:inline">- attach the block volume to your instance </div></span></div><div><span style="font-family:georgia,serif"><div class="gmail_default" style="font-family:georgia,serif;display:inline">
- ssh to your instance and </div><div class="gmail_default" style="font-family:georgia,serif;display:inline">again use dd to copy the .iso file to the newly attached block device (_without_ first making a file system on it)</div>
</span><br></div><div><span style="font-family:georgia,serif"><div class="gmail_default" style="font-family:georgia,serif;display:inline"> $ dd if=/home/<user>/</div></span><span style="font-family:georgia,serif">mycdrom-contents.iso<div class="gmail_default" style="font-family:georgia,serif;display:inline">
of=/dev/sdX (where sdX is the newly attached block device)</div></span></div><div><div class="gmail_default" style="font-family:georgia,serif">- detach the block device and attach/re-attach to other instances to your heart content.</div>
<div class="gmail_default" style="font-family:georgia,serif"> If the second part did not make sense to you, I would recommend looking at the documentation at <a href="http://docs.openstack.org/trunk/openstack-compute/admin/content/starting-images.html" style="font-family:arial" target="_blank"><div class="gmail_default" style="font-family:georgia,serif;display:inline">
