Hello.
I just upgraded my ONE 5.4.13 to 5.6.0 on my Ubuntu 16.04 and I have a critical issue:
https://github.com/OpenNebula/one/issues/2355
The strange thing is to be unable to do onevm show -x <VMID> when there is non ASCII characters but I can display the <VMTEMPLATE/> of that offending <VM/> :-/
I would like to know if it’s only me or if someone else has the same.
It looks like I will be forced to downgrade my OpenNebula 
Regards.
