Real hard disk controller is not (and should not be!) 
visible in a guest domain.
Guest domain uses PV-interfaces to the domain 0 
to access devices.

Try to edit your config
and change sda to hda:

====================================================
kernel = "/boot/vmlinuz-2.6.18.8-xen"
ramdisk = "/boot/initrd.img-2.6.18.8-xen"
memory = 256
name = "fc6"
vif = [ 'bridge=xenbr0' ]
disk = [ 'file:/second/fc6_domudisk,hda1,w' ]
root = "/dev/hda1 ro"
====================================================
