I do this all the time, either directly from the CD/DVD or ISO files, and it 
works fine. [My work is with HVM mode of Xen, which essentially means that I 
have to install "unpatched" OS's all the time, so I install XP, Win2K3, SuSE, 
etc, etc every now and again - even "Memtest86" works in Xen HVM if you like 
(at least it did a while back)].

Can you see if the /var/log/xen/qemu*.log contais anything useful, likewise for 
/var/log/xen/xend{,-debug}.log ?
