I tried to reproduce this, but I did not have any issue (with an iso). 
Also I could not understand why maxmem will have an issue with a drive. 
Also, spice+qemu on debian does not work well, so I'm not sure if I will 
have the same issue. When you found the issue related to the "device not 
found", do you have run the VM without qxl and spice ?

I've just send a patch that fix a memory mapping issue (at least for 
me), could you try with it? :
http://lists.xen.org/archives/html/xen-devel/2012-03/msg00627.html

Then, do you have the same issue if you use an .iso instead of /dev/sr0 
as a cdrom ?
