Couple of my findings:

2017-04-30 16:19:34.894+0000: 870: debug : virDriverLoadModuleFile:49 : Load module file '/usr/lib/libvirt/storage-backend/libvirt_storage_backend_rbd.so'
2017-04-30 16:19:35.324+0000: 870: debug : virDriverLoadModuleFunc:71 : Lookup function 'virStorageBackendRBDRegister'

it takes nearly .5s to load libvirt_storage_backend_rbd.so

But apart from that there is nothing unusual in the logs. So how do you observe the hang? How long it is anyway - assuming it goes away after some time. Or does it hang indefinitely?

BTW: is this all the debug messages you have? Because in there, the last line is how libvirtd starts qemu-system-x86_64 in order to fetch its capabilities. I'd expect libvirt setting qmp_capabilities on the monitor at least.
