Please connect gdb to the hung process and get a stack trace to find
out where it's hanging.
'strace -p ...' output might also be enlightening, if it is not hung
but doing "something" (albeit not making progress).
I should also note that if qemu-img convert hits a lot of zeroes in
the source (possible, because fstrim wasnt successful), then it will
consume CPU skipping them, but won't write anything for a while.
