Just for reference, this is a well know issue with some QEMU versions
that don't support blockcopy command.  You just need to get the right
QEMU binary built and installed if you don't have the right one
available in your distro.  There are some instructions around  that may
help you: https://www.jrssite.com/wordpress/?p=302
