I added this fix and tested it against a Python HTTP server (which does not support ranges): $ cd /tmp $ python -m SimpleHTTPServer [in another window ...] $ http_proxy= ./qemu-io -r http://127.0.0.1:8000/test1.img -c 'read -v 0 512' CURL: Error opening file: Server not supporting range. qemu-io: can't open device http://127.0.0.1:8000/test1.img no file open, try 'help open' [against another server which does support ranges ...] $ LD_LIBRARY_PATH=~/d/curl/lib/.libs http_proxy= ./qemu-io -r http://libguestfs.org/index.html -c 'read -v 0 512' 00000000: 3c 21 44 4f 43 54 59 50 45 20 68 74 6d 6c 20 50 ..DOCTYPE.html.P [etc] By the way I think it would be better if the error message said "Server does not support 'range' (byte ranges)."
