I am new to OpenNebula, the cloud is up and running but the VM is failed to be submitted to a node. I got the following error from the log file.

ERROR: Command "scp ubuntu:/opt/nebula/images/ttylinux.img

node01:/var/lib/one/8/images/disk.0" failed.

ERROR: Host key verification failed.

Error excuting image transfer script: Host key verification failed.

The key verification keeps failing. I need to know what is going wrong ... thanks :)

You need to make sure that you ssh as oneadmin between the computers and accept them as a known host.

Make sure that you ssh as the same hostname that the onevm command is using (i.e. if it's connecting to host name1 you can't ssh to, or you can but then edit the known hosts file to correct this).
