Please merge Yehuda's fix for configure when you resend the patch. What's the easiest way to try it out? I tried to use vstart.sh and copy the generated ceph.conf to /etc/ceph/ceph.conf so that qemu-img etc. find the monitor address. However, that leads to a hang when I try "rbd list" or "./qemu-img create -f rbd rbd:data/test.img 4G", so I seem to be missing something. The only thing I have achieved until now with my attempts of trying it out (and trying wrong things, of course) is that I stumbled over the the following segfault in librados: Program received signal SIGSEGV, Segmentation fault.
