Hi,

CEPH_HOST datastore variable doesn't like IPv6 addresses, even enclosed in brackets. The address is splitted at first ":" assuming the second section is a port number in the resulting libvirt xml deployment file.
See commit b559b32, LibVirtDriverKVM.cc, line 380

Thanks,

Laurent

Hmm, I about to launch a ceph cluster in a week from now based completely on IPv6. Is there a workaround for now? Ceph can't be run in a "dual-stack" mode ...

Yes you can use the hosts names as in /etc/hosts, this problem arises when you try to use the IPv6. The solution is to use getaddrinfo in oned and not the :-split.
