Hi.
version opennebula 5.8.1-1 and 5.6.0
root@onenode-2:~# onedb update-body vm --id 55
Editor not defined
exit
root@onenode-2:~#
Why can’t I run “onedb update-body vm” command?
You have no environment variable EDITOR. For example, to use vi as editor you should do the following:
export EDITOR=vi
onedb update-body vm --id 55
Don’t forget to save before exiting the editor

thank you very much
