What is the host CPU you are using?
I came across the same error few days ago, but without running OST, I
tried running with Lago:
fc24 host -> el7 vm -> el7 vm.
I have a slight suspect that it is related to the CPU model we
configure in libvirt, I tried a mixture of few
combinations(host-pass-through, pinning down the CPU model), but it
always failed on the same error:
kvm_put_msrs: Assertion `ret == n' failed.
My CPU is Broadwell btw.
Milan, any ideas? you think it might be related?
