Comment 17 for bug 1592990

Hi Ron,
I'm not the one working on it, just a friendly helper with System z
background.
jfh and xnox are more on it and might be able to share you that.

But for you as a temporary workaround - If you might consider not using
EDEVs ok you can go on working with native FCP disks just fine.
Which btw (I'm an old IBM performance guy) is faster and has less overhead
anyway.

So provide (virtual) HBA adapters to the guests and get it going.
If you want to go that path JFH might find a few howto's for that and share
them with you outside the scope of that bug.
On the other hand if that makes you change "too much" of your setup than
you feel comfortable you better wait for jfh/xnox getting it properly fixed.
