[Xen-users] Using CD drives with Xen 3.0.3 on CentOS 4.4

[Nico Kadel-Garcia <nkadel@xxxxxxxxx>]

I'd like to be able to use a CD drive on the Dom0 to be accessible on 
the DomU systems. I do see some notes involving cdrom drives in the Xen 
3.1 Enterprise notes, and in the VT notes, but not for systems without 
that on-board virtualization feature. And the syntax of the cdrom 
command options are documented nowhere in 3.0.3.
I found completely useless notes at 
http://www.xensource.com/support/3.1/xenserver-userguide.html. 
Unfortunately, the Xen 3.0.3 RPM's for RHEL4 and which seem quite usable 
for CentOS 4.4 do not include even the manual pages of the 
documentation, not even the manual pages or HTML docs, and attempting to 
build them from the SRPM fails miserably. Note that the Fedora SRPM's 
seem to have fixed this: bad RPM's hurt your credibility in the 
developer's world, folks, as badly as poor documentation! Unfortunately, 
the Fedora RPM's have a whole plethora of requirements not easily 
available on RHEL 4.x or CentOS 4.x.
The samples in the xmexample.hvm and xmexample.vti files seem to be 
unhelpful as well. Using the same kernel as Dom0, or the DomU kernel, 
I'm simply not seeing the /dev/hdb or /dev/cdrom entry for the CD drive, 
and it's not showing up in /proc on the DomU at all.
Has anyone else been through this with a non-virtualized CPU as well, or 
with Xen 3.0.3, not the enterprise version?
