@Thiago: This could be an issue in qemu itself [1]. Would you paste your exact versions of libvirt and qemu please? Could it be that this line worked in Kilo because that system used a different version of qemu? If I understand [1] correctly you can work around this issue by using the full IPv6 unspecified address "0:0:0:0:0:0:0:0".
@libvirt subteam:
I guess this bug cannot (shouldn't?) be solved in Nova? I leave it up to you.
