QEMU command line is: qemu-system-x86_64 -enable-kvm -daemonize -monitor unix:./monitor,server,nowait -cpu host -M q35 -balloon virtio -device virtio-scsi-pci,id=3Dscsi -device scsi-hd,drive=3Dhd -drive if=3Dnone,id=3Dhd,cache=3Dwriteback,aio=3Dnative,format=3Draw,file=3Dxxxx= .img,discard=3Dunmap ,detect-zeroes=3Dunmap -device virtio-net-pci,netdev=3Dnet0,mac=3Dxxxx -netdev tap,vhost=3Don,id=3Dnet0,script=3Dxxxx.sh -usbdevice tablet -smp 2 -m 512 -vnc xxxx:yz VM was running fine, except no network traffic was passed from/to it. Shutting down the VM, it hung at "Will now halt." The QEMU process was unkillable, so the only choice was to sysrq-b the entire box. dmesg with sysrq-w attached.
