2.hotplug disk
drive_add auto id=drive_stg0,if=none,snapshot=off,readonly=off,aio=threads,cache=none,format=qcow2,file=/home/kvm_autotest_root/images/storage0.qcow2
{"execute": "device_add", "arguments": {"driver": "scsi-hd", "id": "stg0", "drive": "drive_stg0", "bus": "virtio_scsi_pci0.0"}, "id": "qNtzV8oW"}
3.format the new disk
dd if=/dev/zero of=/dev/sdb bs=1M count=64 oflag=direct && sleep 1; partprobe /dev/sdb
parted -s "/dev/sdb" mklabel msdos
parted -s "/dev/sdb" mkpart primary 0M 15360.0M
partprobe /dev/sdb
yes|mkfs.ext4 -F '/dev/sdb1'
rm -rf /mnt/sdb1; mkdir /mnt/sdb1
mount -t ext4 /dev/sdb1 /mnt/sdb1
4.execute io on disk
/home/iozone_inst/src/current/iozone -az -g 10G -y 32k -i 0 -i 1 -I -f /mnt/sdb1/iozone_test
5.unplug disk
{"execute": "device_del", "arguments": {"id": "stg0"}, "id": "jBVHXCyW"}
6. umount disk
mount|grep sdb ; umount /mnt/sdb1 && sleep 3
7. repeat step2-6 60 times
Expected results
login guest succeed after above steps
Actual results
qemu crash
(not hit crash issue on rhel8.4 /8.6/8.8)
