That's bad, and may be related to Fedora 17's systemd services. Try to remove the comment and restart libvirtd to see if this is the case.
The comment come from
[root@ovirt-node1 ~]# cat /etc/sysconfig/libvirtd:
I know that (see my text above). However, in F16 and before, comments have been stripped before being passed to commandline. Have you tested if all is well when the commment is removed?
I removed the "# by vdsm " line from the config file. And restarted the libvirtd and vdsmd service. But no luck to make "virsh net-list" successful, still got "Segmentation fault", while "virsh -c qemu:///system -r" worked.
Thanks. Please strace that segfault, there's a libvirt bug lying there. And thanks again for finding the vdsm/libvirt configuration problem in F17.
Specifically do the following
# debuginfo-install libvirt # gdb --args virsh net-list (gdb) run ...wait for crash.. (gdb) thread apply all backtrace
