For a long time we've not been able to use Fedora's curl with qemu, but
upstream curl from git just worked. A simple way to test this is to run:
qemu-io http://libguestfs.org/index.html -c 'read -v 0 512'
It will either print something or hang forever.
Thanks for your detailed report and I also read your bugzilla entry on this
issue.
What exactly is that command line doing HTTP-wise? Is it "just" asking for the
first 512 bytes from that URL? If so, shouldn't the plain curl command line
tool also repeat the problem if it was truly a pure libcurl problem? Any
chance you can try to write up a smallish more plain libcurl-using code that
can be used to attempt to repeat the problem?
Oh and btw, when it hangs, does it show it the resolver thread function as the
culprit in a gdb stack trace?
