I ran an adhoc test with this applied which resulted in:

2015-08-12 18:07:26 Z executing ssh ... root@10.80.229.144 virsh migrate --live debian.guest.osstest xen+ssh://lace-bug
error: unable to connect to 'lace-bug.uk.xensource.com:49152': Invalid argument

(note that the domainname for this osstest instance is "xs.citrite.net",
there is such a domain as "uk.xensource.com" which may have come from DHCP
or DNS or something).

So I switched to using $dho->{Fqdn} instead of just $dho->{Name} and tried
again resulting in:

2015-08-12 21:49:22 Z executing ssh ... root@10.80.229.144 virsh migrate --live debian.guest.osstest xen+ssh://lace-bug.xs.citrite.net
error: unable to connect to 'lace-bug.uk.xensource.com:49152': Invalid argument

Which is pretty WTF... Logs for this one are at 
http://xenbits.xen.org/people/ianc/tmp/37828/
http://xenbits.xen.org/people/ianc/tmp/37828/test-amd64-amd64-libvirt-pair/info.html

I'm doing an experiment now with $dho->{Ip} but that seems like it would
just be papering over the issue, whatever it is.

Ian.
