Po-Hsu Lin (cypressyew) wrote : s390x zKVM failed with selftest-setup and intercept test in kvm-unit-tests

Steps:
1. git clone https://git.kernel.org/pub/scm/virt/kvm/kvm-unit-tests.git
2. cd kvm-unit-tests
3. ./configure; make
4. sudo ./run_tests.sh -v

And you will see the detailed command it use, run the one for selftest-setup as root:
# TESTNAME=selftest-setup TIMEOUT=90s ACCEL= ./s390x/run s390x/selftest.elf -smp 1 -append 'test 123'
timeout -k 1s --foreground 90s /usr/bin/qemu-system-s390x -nodefaults -nographic -machine s390-ccw-virtio,accel=tcg -chardev stdio,id=con0 -device sclpconsole,chardev=con0 -kernel s390x/selftest.elf -smp 1 -append test 123 # -initrd /tmp/tmp.gj7cBJS2hH

Run the one for intercept as root:
# TESTNAME=intercept TIMEOUT=90s ACCEL= ./s390x/run s390x/intercept.elf -smp 1
timeout -k 1s --foreground 90s /usr/bin/qemu-system-s390x -nodefaults -nographic -machine s390-ccw-virtio,accel=tcg -chardev stdio,id=con0 -device sclpconsole,chardev=con0 -kernel s390x/intercept.elf -smp 1 # -initrd /tmp/tmp.4QCRdccGRJ

ABORT: intercept: stpx: Unexpected program interrupt: 5 at 0x109dc, ilen 4

SUMMARY: 3 tests, 2 unexpected failures

EXIT: STATUS=127

Tried QEMU 2.10 built from source, this issue still exist.
