I did testing on this and got the same results. The different scenarios are listed here and all match up with original results. I tested with 1:2.11+dfsg-1ubuntu7.18~ppa1 .
Result: worked w/warning:

qemu-system-ppc64le: warning: cap-ccf-assist lower level (0) in incoming stream than on destination (1)
