Hi all, Trying to run ovirt-system-tests using mock_runner.sh on my laptop (i7-6820HQ T460p, RHEL 7.4, kernel 3.10.0-693.17.1.el7.x86_64, qemu-kvm-rhev-2.9.0-16.el7_4.13.x86_64). hosted-engine deploy starts, and fails while running virt-install to create the engine vm (which will be a nested-kvm vm). qemu log on the nested-kvm host0 says: 2018-03-26T08:02:16.727212Z qemu-kvm: error: failed to set MSR 0xd90 to 0x0 qemu-kvm: /builddir/build/BUILD/qemu-2.9.0/target/i386/kvm.c:1843: kvm_put_msrs: Assertion `ret == cpu->kvm_msr_buf->nmsrs' failed. Searched and found this: https://bugs.launchpad.net/qemu/+bug/1665389 which seems very similar, although from a year ago and about a fedora 24 kernel+qemu. The conclusion there is: <quote> Yes, I mean '-cpu host' in the bare metal. There is no workaround; it worked by chance and it triggered other hard to find bugs. </quote> So, what should I/we do? Is there a workaround? How does this work elsewhere? Thanks, -- Didi
