+After converting the Windows 10 system disk from qcow2 to LUKS format with pre-allocated space, the system fails to boot
+Description of problem:
+When converting a qcow2 file containing an installed Windows 10 system to LUKS format, using the --target-is-zero parameter in the conversion command prevents the LUKS image from shrinking. However, when attempting to boot the virtual machine with the converted LUKS file, VNC login shows a black screen, and the system fails to start. If the conversion is performed without the --target-is-zero parameter, the system boots up normally
+Steps to reproduce:
+1. create a luks image
+qemu-img create -f qcow2 --object secret,data=123,id=sec0 -o preallocation=full,encrypt.format=luks,encrypt.key-secret=sec0 encry_ok.qcow2 50G
+2.
+qemu-img convert -t none -T none --object secret,id=sec0,data=123 -f qcow2 ./windows10.qcow2  -n -m 1 --target-image-opts driver=qcow2,encrypt.key-secret=sec0,file.filename=encry_ok.qcow2 --target-is-zero
+
+windows10.qcow2 container windows20 system and  it can be booted
+3.
+./qemu-system-x86_64  -accel kvm -cpu SandyBridge  -object memory-backend-memfd,id=mem1,size=4G -machine memory-backend=mem1  -smp 4  -object secret,id=sec0,data=123,format=raw -drive if=none,driver=qcow2,file.filename=/sdc1/luzhipeng/encry_ok.qcow2,encrypt.key-secret=sec0,id=drive0,cache=none  -device virtio-blk,drive=drive0,bootindex=1  -monitor stdio -vnc :4
+
+4. vnc shows a black screen, and the system fails to start
+
+5. if use convert command:
+qemu-img convert -t none -T none --object secret,id=sec0,data=123 -f qcow2 ./windows10.qcow2  -n -m 1 --target-image-opts driver=qcow2,encrypt.key-secret=sec0,file.filename=encry_ok.qcow2
+
+6. the windows10 system can start successful
