Qemu does not support "info blockstats" now.
It doesn't? Mine is more than happy to accept that command:
$ x86_64-softmmu/qemu-system-x86_64 -nodefaults \
-drive if=none,id=drv0,driver=null-co \
-monitor stdio
QEMU 2.5.90 monitor - type 'help' for more information
(qemu) info blockstats
drv0: rd_bytes=0 wr_bytes=0 rd_operations=0 wr_operations=0
flush_operations=0 wr_total_time_ns=0 rd_total_time_ns=0
flush_total_time_ns=0 rd_merged=0 wr_merged=0 idle_time_ns=0
