Please can you post the command line args of your VM? I use something like ./x86_64-softmmu/qemu-system-x86_64 -chardev 'socket,id=qmp,path=/var/run/qemu-server/101.qmp,server,nowait' -mon 'chardev=qmp,mode=control' -pidfile /var/run/qemu-server/101.pid -m 1024 -object 'iothread,id=iothread-virtioscsi0' -device 'virtio-scsi-pci,id=virtioscsi0,iothread=iothread-virtioscsi0' -drive 'file=/backup/disk3/debian-buster.raw,if=none,id=drive-scsi0,format=raw,cache=none,aio=native,detect-zeroes=on' -device 'scsi-hd,bus=virtioscsi0.0,channel=0,scsi-id=0,lun=0,drive=drive-scsi0,id=scsi0' -machine "type=pc,accel=kvm" Do you also run "stress-ng -d 5" indied the VM?
