Hello, On an OpenStack node you may be able to use libxenstore instead of libvirt. You'll need to recompile hsflowd to try this. Looking at trunk/src/Linux/Makefile it appears to look for libvirt first, but you can override that by compiling hsflowd like this:
make clean make LIBVIRT=no The Makefile will then test for libxenstore and libxenctrl. If it finds them it will compile with -DHSF_XEN (instead of -DHSF_VRT), and you may get better results. Please let me know what happens.
