Bug Description

Issue spotted on node s2lp6g004 (Artful zVM works fine) and s2lp6g002

Steps:
 1. git clone --depth=1 https://git.kernel.org/pub/scm/virt/kvm/kvm-unit-tests.git
 2. cd kvm-unit-tests; ./configure; make
 3. TESTNAME=intercept TIMEOUT=90s ACCEL= ./s390x/run s390x/intercept.elf -smp 1

Result:
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.VtbQbGoJzf
