Hello,
In our scene, we need to delete dirty-bitmap created by using qmp command
'block-dirty-bitmap-add'. we can use qmp command 'block-dirty-bitmap-remove'
to remove bitmap. Then I think that we should add a new function in qemu-img
to do the same work.
The command format is: qemu-img removebmp file-name bitmap-name
I test the function by using qmp command to create a named dirty-bitmap in
qcow2 image, then shutdown the vm and using qemu-img to remove it. Then I
test to remove a bitmap with 'IN_USE' flags in qcow2 file, and it works.
I alse test to do the same job to the qcow2 image encrypted by luks.
Please help to review. Thanks.

Add new command 'removebmp' to remove bitmap in qcow2 file. The format
is: qemu-img removebmp qcow2-file-name bitmap-name
