(Don't other scenarios end at black screen because you have -no-shutdown?) Does it fail the same if you enter 'system_powerdown' in the qemu monitor? (Normal shutdown from guest works?) Can you share the qemu command line? I can't reproduce with the one I tried ... (It is a problem with virtio storage, so it would be great if you could minimize it around that.) Thanks. > (Don't other scenarios end at black screen because you have -no-shutdown?) QE didn't test these scenarios with option -no-shutdown. > Does it fail the same if you enter 'system_powerdown' in the qemu monitor? > (Normal shutdown from guest works?) According to bug980692 QE can't confirm whether 'system_powerdown' in the qemu monitor successfully. However, it is normal if guest run in runlevel3. And shutdown inside guest normally. > Can you share the qemu command line? I can't reproduce with the one I tried my full command line: /usr/libexec/qemu-kvm -cpu SandyBridge,+kvm_pv_eoi -m 2048 -smp 2,sockets=1,cores=2,threads=1 -M pc -enable-kvm -name RHEL7 -drive file=/home/guest/RHEL7.1-64.qcow2,if=none,format=qcow2,werror=stop,rerror=stop,cache=none,id=drive-blk -device virtio-blk-pci,drive=drive-blk,id=virtio-disk0 -nodefaults -nodefconfig -monitor stdio -netdev tap,id=hostnet0 -device virtio-net-pci,netdev=hostnet0,mac=be:ba:0a:82:5a:78,id=net0 -vga qxl -spice port=5901,disable-ticketing -qmp tcp:0:4440,server,nowait -watchdog i6300esb -watchdog-action shutdown -serial unix:/tmp/ttys0,server,nowait > (It is a problem with virtio storage, so it would be great if you could > minimize it around that.) QE will minimize and provide it later. additionally, QE tested it again but can't reproduce it as well and get some info as following: [ 109.969052] i6300esb: Unexpected close, not stopping watchdog!
