Yes you can load balance it like any webpage.

Only gotcha is the vncproxy, it uses websockets that might be problematic
for level 7 loadbalancers.
If you use tcp loadbalancing you should be fine though.

I'm having trouble getting Horizon (Folsom Stable) to point to Keystone at
another IP. All I should have to do is

vim openstack_dashboard/local/local_settings.py
  OPENSTACK_HOST = "123.123.123.123"
sudo /etc/init.d/apache2 restart

Correct?

But the login page reads,

  An error occurred authenticating. Please try again later.

I dropped the Horizon DB and recreated it but that didn't help. Nothing
helpful in /var/log/apache2/horizon_error.log or
/var/log/apache2/horizon_access.log either.

Am I missing something obvious?

Thanks,
Everett
