Dave, 
if you have spare PU on your z890, I would strongly
recommend to get IFL for test purposes which can be
free for 3 or 6 months. It is also possible to get
trial contract for z/VM, which is a good idea.
Are your CPs on full speed or not ? If you assign one
capped CP which you share with production, it will be
waaaay slower than IFL which is full speed. And slow
response is not a good start for PoC.
We have many customers running Linux on z890 happily,
most of my customers run it on IFL with or without
z/VM.
