he-basic-ansible_suite_master: failed to set MSR 0xd90 to 0x0

[Yedidyah Bar David]

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:

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.

So, what should I/we do? Is there a workaround? How does this work elsewhere?

Thanks,
