[libvirt] Web Interface -> LibVirt Communication?

[Michael March]

This might not be the 'right way' but here is how I handled 
communication to each Xen instance my web interface is managing. I used 
the ssh style connect string.. even if it was a local instance.. here is 
a line ripped right from my code:

server_list={"michael":['127.0.0.1',""], "tito":['192.168.101.5',""], 
"jermaine":['192.168.101.6',""}

.. then later in my code...

for server in server_list:
    server_list[server][1] = 
libvirt.open('xen+ssh://root@'+server_list[server][0]+'/')
    if server_list[server][1] == None:
        print 'Failed to open connection to the hypervisor'
        sys.exit(1)

.. in this setup you MUST have the ssh public key of the user the web 
server runs as in the 'root' account of each server it manages.. again, 
this might not be 100% kosher.. but it works.
