Re: [lago-devel] [ovirt-devel] OST: vm_run fails for me (basic-suite-master)

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? Nadav.
