[one-users] Problem creating/adding host. Bug?

[Carlos Martín Sánchez]

Hi,

You can use the command "onehost sync" to force OpenNebula to copy the
remote scripts in the next monitorization cycle.

The error message appears in the host template because is it a flexible way
to include information for components in the upper layers, like Sunstone.
This way you can get error messages instantly instead of having to open and
search the log files, and you can delete that error message once you have
fixed the issue.

Regards.
