When trying to migrate a VM the destination libvirtd
virGetHostnameLocalhost throws an internal error.
I issue this command from the source host.
> virsh migrate rel-vm1 qemu+tls://croton/system
error: internal error canonical hostname pointed to localhost, but this is
not allowed
The destination host throws the error:

The libvirt version is the tip of git:
[root@croton rel-vm1]# virsh version
Compiled against library: libvir 0.7.7
Using library: libvir 0.7.7
Using API: QEMU 0.7.7
Running hypervisor: QEMU 0.12.1
Changing qemudDomainMigratePrepare2 call to virGetHostnameLocalhost
from: if ((hostname = virGetHostnameLocalhost(0)) == NULL)
to: if ((hostname = virGetHostnameLocalhost(1)) == NULL)
seems to fix the problem.
But maybe this is only masking a another problem.
