This issue is also exist on power9(fasttrain)
Power9:
alt-7.6:

what's more, this issue is ppc fasttrain only(i.e, x86_64 didn't hit it, ppc slow train didn't hit it too)

I have tried with qemu-kvm-3.1.0-3.el8 on destination host, the result is PASS.
host A(rhel7.6)
4.14.0-115.5.1.el7a.ppc64le
qemu-kvm-rhev-2.12.0-18.el7_6.3.ppc64le
SLOF-20171214-2.gitfa98132.el7.noarch
host B(rhel8.0)
4.18.0-57.el8.ppc64le
qemu-kvm-3.1.0-3.module+el8+2614+d714d2bb.ppc64le
SLOF-20171214-5.gitfa98132.module+el8+2618+c5e2b86b.noarch
steps are same with comment 0.
result:
migration succeed and vm works well.
So, I think this bug is fixed.
