XMPP Server on CloudStack Management Server

[hossein zabolzadeh]

Hi again.
I want to add instance messaging system to the cloudstack management server
architecture, to provide online chat capability with my VMs. I wrote a
simple agent to be installed on every VMs, to provide chatting mechanism
with each of them.
So, how can I add XMPP to the cloudstack architecture?
In other words, how its better to be implemented?
Or is there any other method to provide this functionality in a better and
standard way(I mean CloudStack compliency)?
Is there any alternative to XMPP server which is existed on the current
cloudstack architecture?
Thanks in advance.
