hi Scott,

I don't understand this sentence.

kvm ppc64 crash if run by qemu.

You didn't show that log.

in the kernel( 4.5 too)all is enabled we had a base .config by freescale/nix
where kvm options and book3e  where enabled.

You should start with corenet64_smp_defconfig, and enable KVM options plus
PPC_QEMU_E500.

my suspect is this can be an generated issue by  the host uboot

Host U-Boot has nothing to do with KVM.

 or a missed tdb parameter and not a linux kernel problem.

What is tdb?
