Hi Jason, while running my s390-ccw bios tests, I noticed that network booting seems to be broken now. This used to work before: s390x-softmmu/qemu-system-s390x -nographic -accel kvm \ -bios pc-bios/s390-ccw/s390-ccw.img \ -global s390-ipl.netboot_fw=pc-bios/s390-ccw/s390-netboot.img \ -netdev user,id=n1,tftp=/boot,bootfile=vmlinuz-4.18.0 \ -device virtio-net-ccw,netdev=n1,bootindex=1 Now it simply fails with "! No IPL device available !". Could you have a look at it, please? Thanks, Thomas
