I tried the "opensuse101-20060514.tbz"opensuse101-20060514.tbz" from there 
and  after "tar -xjf  "opensuse101-20060514.tbz" it contains the 
files "hda6.img", "opensuse101.cfg" and "vmlinuz-"

I'm not sure what you mean with "using cp" but this is what I did:

	# cp vmlinuz- /
	# vnconfig -c vnd0 hda6.img

	# vi /usr/pkg/etc/xen/opensuse
		kernel = "/vmlinuz-"
		memory = 300
		name = "opensuse"
		vif = [ 'mac=aa:00:00:50:02:f0, bridge=bridge0' ]
		disk = [ 'phy:/dev/vnd0d,0x306,w' ]
		root = "/dev/hda6 rw"

This seems to work now: the Linux domU boots (with many error messges!) 
and I can login as root, but there's no working network 
configuration, ...might be some more work necessary as expected, to get 
it usable :-(  

Many thanks for your help & Greetings,
