If reporting bugs, run virt-v2v with debugging enabled and include the 
complete output:

  virt-v2v -v -x [...]


Expected results:
Connect and be able to convert.


Additional info:
Remote xen server is:
Ubuntu 12.04.2 LTS
libxen-4.1                           4.1.6.1-0ubuntu0.12.04.11
Comment 1 Jiri Denemark 2016-09-15 07:32:42 UTC 
Is libvirtd running on the remote host?
Comment 2 Artur Cuvasov 2016-09-19 20:40:46 UTC 
You are right, there could have been a message for that... Another issue now: libvirt does not allow to convert a running virtual server, what is understandable, however when you shut it down (xen shutdown G1BATCH) - it does not find a machine.
