Fix included in qemu-kvm-rhev-2.10.0-21.el7_5.2 Verified with qemu-kvm-rhev-2.10.0-21.el7_5.2, the problem has been resolved, so set its status to "verified".
Test version:
qemu version: qemu-kvm-rhev-2.10.0-21.el7_5.2
kernel version:3.10.0-862.el7.x86_64
Test steps:
1. start guest with cmds:
/usr/libexec/qemu-kvm \
-name 'avocado-vt-vm1' \
-machine pc \
-vga std \
-object iothread,id=iothread0 \
-object iothread,id=iothread1 \
-device virtio-scsi-pci,id=scsi0,bus=pci.0,addr=03,iothread=iothread0 \
-drive id=drive_image1,if=none,snapshot=on,aio=native,cache=none,format=qcow2,file=/home/kvm_autotest_root/images/rhel75-64-virtio.qcow2 \
-device scsi-hd,id=image1,drive=drive_image1,bus=scsi0.0,lun=0 \
-device virtio-net-pci,mac=9a:b2:b3:b4:b5:b6,id=iduCv1Ln,vectors=4,netdev=idKgexFk,bus=pci.0,addr=05 \
-netdev tap,id=idKgexFk,vhost=on \
-m 4096 \
-smp 4,maxcpus=4,cores=2,threads=1,sockets=2 \
-cpu host \
-vnc :1 \
-enable-kvm \
-monitor stdio \
-device virtio-scsi-pci,id=scsi1,bus=pci.0,addr=04,iothread=iothread1 \
-drive id=data_image1,if=none,werror=stop,rerror=stop,cache=none,format=qcow2,file=/home/test.qcow2 \
-device scsi-hd,id=data1,drive=data_image1,bus=scsi1.0,lun=0 \
2.Run dd in guest:
dd if=/dev/zero of=/dev/sdb bs=4K count=1000000000 oflag=direct status=progress
3. During dd running, quit qemu
(qemu)quit
Test result:
QEMU quit successfully.
