Title:
  Zesty s390x zKVM failed with selftest-setup and intercept test in kvm-
  unit-tests

Status in ubuntu-kernel-tests:
  Fix Released
Status in linux package in Ubuntu:
  Invalid
Status in qemu package in Ubuntu:
  Invalid

Bug description:
  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
  PASS: selftest: true
  PASS: selftest: argc == 3
  PASS: selftest: argv[0] == PROGNAME
  PASS: selftest: argv[1] == test
  PASS: selftest: argv[2] == 123
  PASS: selftest: 3.0/2.0 == 1.5
  PASS: selftest: Program interrupt: expected(1) == received(1)
  ABORT: selftest: Unexpected program interrupt: 5 at 0x12b94, ilen 6

  SUMMARY: 7 tests

  EXIT: STATUS=127

  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
  PASS: intercept: stpx: store prefix
  FAIL: intercept: stpx: Program interrupt: expected(4) == received(0)
  FAIL: intercept: stpx: Program interrupt: expected(6) == received(0)
  ABORT: intercept: stpx: Unexpected program interrupt: 5 at 0x109dc, ilen 4

  SUMMARY: 3 tests, 2 unexpected failures

  EXIT: STATUS=127

  This is not a regression as we just add the test for s390x in this
  cycle.
