[Libguestfs] [PATCH virt-v2v 0/2] -o qemu: Fix various things

I guess this output mode is not used very much because it's quite broken at the moment. In particular it used the qemu -balloon option, removed in 2018. Also my recent fix to vsock support was broken. I've tested it a bit more now and it's now possible to run the shell script to boot a converted Linux guest. Rich.
