Bug 1651195

Fix included in qemu-kvm-2.12.0-45.module+el8+2313+d65431a0

Vitaly,

How to add "hyperv-testdev device" to qemu-kvm command line and verify this bug? Thanks.

I suggest you just use kvm-unit-tests:

git clone git://git.kernel.org/pub/scm/virt/kvm/kvm-unit-tests.git
cd kvm-unit-tests
./configure
make
./x86/run x86/hyperv_synic.flat -cpu kvm64,hv_vpindex,hv_time,hv_synic,hv_stimer -device hyperv-testdev

(or just run all tests with ./run_tests.sh)

Tested bug with the qemu-kvm-2.12.0-45.module+el8+2313+d65431a0 and kernel 4.18.0-48.el8.x86_64. QE tested 2 scenarios on host.

I have 1 small question.

Q1) S1 only covered "Hyper-V SynIC test", no cover hyperv_stimer. Can this result verify this bug?

Q2) Accroding to this result, Can I set this bug as verified?

You can run stimer test separately too,

./x86/run x86/hyperv_stimer.flat -cpu kvm64,hv_vpindex,hv_time,hv_synic,hv_stimer -device hyperv-testdev

>

PASS hyperv_synic (1 tests)
PASS hyperv_stimer (12 tests)

Yes, this looks good.

Thanks Vitaly, According to comment7, set this bug as verified.
