[one-users] Problems running VM

Tue Aug 27 02:06:57 PDT 2013

Hi André,

How did you end up with the wrong kvm.conf path in oned.conf? I simply
copied the default configuration.

And yes, localhost is treated just like any other host, OpenNebula needs
you to configure passwordless ssh for the oneadmin account.

Regards
