[one-users] Opennebula livemigrate

[Javier Fontan]

Hello Fermin,

Seems that there is some problem at libvirt/kvm level. Can you check  
log files stores in /var/log/libvirt in the node that was executing  
the VM for some problem? Check also log files in the machine that was  
going to receive the VM.

Another test you can do is executing the migration by hand using virsh  
commands to check if something is broken.

Bye
