Thanks for the feedback. I'm only using the Open Sourced version of xen,
so that's all I've tested with. I'm a little surprised (but pleased)
that it works at all under XenSource - I hope you tested on a test
machine first :)

Hot adding of network and disk devices has worked at various points
along the way, at least under the Open Sourced version of Xen. The
interaction between the various Xen device states and the Windows
devices states is complicated :)
I can't test it right now as my test box keeps BSoD-ing. I think I did
something stupid with ntfs-3g while trying to resurrect it :(

I did fix a bug in (I think) 0.9.12-pre2 which was affecting DVD-sized
cd/dvd images. That would cause the CD drive to appear but fail to read
though, which doesn't sound like the problem you are having.
I'm not sure if all of these commands are available under the XenSource
version, but:
. send me the output of 'xenstore-ls /local/domain/<id>/device'
(substitute <id> for the domain id of the domain in question)
. In device manager, you should see one 'Xen Block Device Driver'
adapter per device (disk or cdrom). For each one, can you tell me the
value of 'Device Instance Id' in the Properties -> Details tab?
. send me a copy of your DomU config
. if you know how to use the windows debugger, connect that to the DomU
and send me the output. If you don't know, then just the above stuff
might be sufficient to get started - it may be that the XenSource
version does things a little differently for CDROM's or something which
I might be able to tell immediately.
Thanks
James
