The hostname for both hosts is "ubuntu", which is why it fails. You
should assign distinct hostnames to both hosts. And ideally, both
hostnames should be resolvable from both hosts and lead to the
corresponding IP address. See
http://wiki.libvirt.org/page/Migration_fails_with_%22Unable_to_resolve_address%22_error

Success!!!
I change hostname of my target (sudo hostname ubuntu40)
And I modify my command as in link above.
-->
virsh --connect qemu:///system  migrate --live ubuntuShared5 qemu+ssh://192.168.X.X/system tcp://192.168.X.X--unsafe --verbose
loic at 192.168.X.X's password: 
Migration: [100 %]

And on target VM, I see migrated vm:
loic at ubuntu:~$ virsh --connect qemu:///system list
 Id    Name                           State
----------------------------------------------------
 2     ubuntuShared5                  running

Thanks a lot for help, 
I hope this topic will help others!

I use libvirt-1.0.2.

Michal asked for "version" command rather than "--version".
