Workaround is to precreate the new file of the proper size and pass -n

qemu-img create -f qcow2 base 32M
qemu-img create -f qcow2 -o backing_file=base disk
qemu-img resize /home/vishvananda/disk 64M
qemu-img create -f qcow2 -o backing_file=base test 64M
qemu-system-x86_64 -drive file=disk,id=vda -vnc :1 -monitor stdio
QEMU 1.3.0 monitor - type 'help' for more information
(qemu) drive_mirror vda test -n
