Hey everyone, sorry for spamming, but I thought it might be a good idea to share with you how I found out how to fix this issue!!! It was quite tedious actually.
After reviewing the logging documents, I set the following environment variables export LIBVIRT_DEBUG=4 export LIBVIRT_LOG_OUTPUTS="1:file:/var/log/virsh.log" Once that was set, I ran the following to monitor the log file: tail -f /var/log/virsh.log When I ran the live migration this time around, this was the output I received on that error 23:35:47.102: error : server_error:7231 : operation failed: migrate failed: migrate "tcp:scott:49154" migration failed As you can see from this, it was trying to live migrate using the hostname "scott" instead of the actual IP once it established the session on both ends using ssh. To fix this, I simply modified the /etc/hosts file and included scott to resolve to the remote system and voila, it worked like a charm and quickly. Hope this is helpful to anyone getting random UNKNOWN ERROR messages, and thanks to the mailing list for helping so selflessly every time! Keep up the good work!

I wonder if I overlooked something else...although it's not possible, because I really read the tutorials thoroughly. Also, I checked the lists already - I check them every time before I post something new. I don't wanna end up spamming the whole list here! :) Thanks very much, for the help up to now! -----Ursprüngliche Nachricht----- Von: Steffen Neumann [mailto:sneum...@ipb-halle.de] Gesendet: Montag, 30.

I CHeck out the list archives, in opennebula-2.2 you need to change qmeu to qemu+ssh in one of the scripts. If you don't find it, ask again.
