QEMU just doesn't support live migration for some disk formats, you can see that from the block device code in qemu:

mriedem@ubuntu:~/git/qemu$ grep -R QERR_BLOCK_FORMAT_FEATURE_NOT_SUPPORTED ./block ./block/vvfat.c: QERR_BLOCK_FORMAT_FEATURE_NOT_SUPPORTED, ./block/snapshot.c: error_set(errp, QERR_BLOCK_FORMAT_FEATURE_NOT_SUPPORTED, ./block/snapshot.c: error_set(errp, QERR_BLOCK_FORMAT_FEATURE_NOT_SUPPORTED, ./block/vpc.c: QERR_BLOCK_FORMAT_FEATURE_NOT_SUPPORTED, ./block/vdi.c: QERR_BLOCK_FORMAT_FEATURE_NOT_SUPPORTED, ./block/qcow.c: QERR_BLOCK_FORMAT_FEATURE_NOT_SUPPORTED, ./block/vmdk.c: QERR_BLOCK_FORMAT_FEATURE_NOT_SUPPORTED, ./block/vhdx.c: QERR_BLOCK_FORMAT_FEATURE_NOT_SUPPORTED,

Should really be using raw or qcow2.
