We were setting it based on whether it was supported and that lead to
setting it to NULL, which our JSON code caught. However it ended up

$ virsh blkdeviotune fedora vda --total-bytes-sec-max 2000
error: Unable to change block I/O throttle
error: internal error: argument key 'group' must not have null value
