[one-users] Cannot contact server: is it running and reachable?

[kenneth at apolloglobal.net]

Hi, 

Thanks for the reply. 

* [sunstone-oned] Is the connection
between sunstone-server and oned fast? 

- The sunstone server and oned
is on the same physical server. I'm no longer using the KVM sandbox. The
front end have a dedicated machine. 
* [sunstone] Check if the nokogiri
gem is installed in the physical machine where sunstone-server is
running, if it's not installed rexml will be used by default (a bit
slower) 
- I ran install_gems and everything went was installed except
for the nokogiri. Here is the error. Any way to fix this?

rake="/usr/bin/rake" gem install --no-ri --no-rdoc nokogiri 
ERROR:
Error installing nokogiri:
nokogiri requires Ruby version >=
1.9.2.
Error executing rake="/usr/bin/rake" gem install --no-ri
--no-rdoc nokogiri 

* [sunstone] Using ruby 1.9 instead of 1.8 
- I'm
running ubuntu and tried this. Notification Error is still showing.

just installed OpenNebula a few days ago. It is running fine, but every
minute or so this message appears on the lower right of the OpenNebula
webmin page. It is a notification bubble. It also appears when I used
the KVM sandbox from the opennebula website. Now that the front end is
in a seperate physical machine, the notification still appears.

* [sunstone] By default sunstone-server runs using the thin server, in a
production environment it's recommended to use passenger + apache/nginx
instead. [1] * [oned] Use mysql instead of sqlite as oned backend. [2]
