It is not related to the problem you are seeing, but you will need 
virtio_console kernel support before you get any console output.

I am currently at the KVM forum, but I plan to continue the following patch 
set:

This patch set should work nevertheless.

Hmm,  I have no z900 to test on, currently we prototype on an z9. It used to 
work under z/VM - I have to retest.

Can you run kuli with the -sysdump parameter and check 
in /sys/kernel/debug/s390dbf/kvm-*/sprintf for

"unhandled validity intercept code %d"
and tell us about %d
while the dump is taken?
