[one-users] Help with VM launch

Thu Jun 9 09:40:08 PDT 2011

Hi,

I think the deployment is failing because the host is en error state.

It seems that when ONE is trying to monitor it, the 192.168.1.5 host
closes the connection.

You should make sure that you are running OpenNebula commands with the
'oneadmin' user and that this user has passwordless ssh access to the
host. You can assign a password to the oneadmin unix user with 'passwd
oneadmin' as root. Then you should be able to login with it and test if
'ssh 192.168.1.5' is working well.

Hope it helps,

Hector
