[one-users] VPN Access ...

Tue Aug 14 13:38:21 PDT 2012

Hi

This seems to be a wrong installation of the guest OS, it is either missing
some modules to mount the FS or the disk does not have a valid OS
installation. As far as it seems there is no error from the OpenNebula
point of view...

Cheers

Ruben
