Hi Tim This is very much appreciated.
From your email, if I am correct. I do the following in this order --- (1) install xenserver v6.2 (2) setup extra management network for storage (3) setup eqlx as isci and multipathing (4) install the cloudstack requirements for the cloudstack server(s) to access-control xenserver (5) create the storage integration in cloudstack as 'presetup' Please advise where I can find details of presetup or is it detailed in one of the docs. ALSO Can you explain how xenserver is used and managed ny cloudstack. For example -- (1) do I manage all instances and primary-secondary storage from cloudstack or xenserver? (2) do I manage the users, security, networking [advanced] from cloudstack? Is there anything else I need to know or be aware of before going down this route?
