Hi All,

(I already posted this on openstack mail list, but perhaps it's more a 
developer stuff :))
Some Tricky questions I ask help for (email 2 of 2):

(please refer to a scenario with Openstack+Quantum, so we can have complex 
networks)

Nova Compute
Are booted VMs independent by other nova/quantum services?
I mean: when a VM is already booted does it need in any case to dialog with 
other nova/quantum services (apart from nova compute) like quantum, the quantum 
plugin agent, the keystone etc etc???
For example and in other words: when a VM is running might I turn off the 
quantum server (or even physically disconnect the dedicated server itself? )?

Because...it this is NOT possible this means that the various servers (for 
example the quantum) are involved during the whole lifecycle of a VM.....could 
this be a bottleneck?, something to take in count for high availability and 
performance?


Thanks in advance for any help

Best Regards

Marco
