As well as pushing to pretest I also kicked off a quicker local run, which
is at http://xenbits.xen.org/people/ianc/tmp/37824/ .

http://xenbits.xen.org/people/ianc/tmp/37824/test-amd64-amd64-libvirt
-pair/info.html shows this in the log for 21.ts-migrate-log.log:

    2015-08-12 11:22:47 Z executing ssh ... root@xxxxxxxxxxxxx virsh migrate 
--live debian.guest.osstest xen+ssh    ://lace-bug
    error: End of file while reading data: nc: invalid option -- 'U'
    nc -h for help: Input/output error

I've no idea how or why nc is involved, but it seems it doesn't like Debian
Wheezy's implementation?

Ian.
