Forgot to note: Before blockcopy, the current block device is
snap1.qcow2 (after too, it's the same, since we didn't `--pivot` to the
copy.
Now, let's do a live blockcopy (with a '--finish' to
graecully finish
the mirroring):
$ virsh blockcopy --domain testvm2 vda \
/export/dst/copy.qcow2 \
--wait --verbose --finish
Examine the contents of the above 'copy':
$ guestfish --ro -a copy.qcow2

If I'm reading the man page of 'blockcopy' correctly, shouldn't it
'flatten' the entire chain, by also copying the contents of base into
copy.qcow2? i.e. the 'copy' should have files (including the file foo
from 'base':
foo, bar, baz, jazz
True or false?
