Open Stack

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 1 of 2):


Quantum Network object
In the "openstack networking guide"->"Using Openstack compute with Openstack"->" Advanced VM creation" (http://docs.openstack.org/grizzly/openstack-network/admin/content/advanceed_vm_creation.html) there are example boot a VM on one or more NETWORKs (meaning the quantum Network object):
nova boot --image <img> --flavor <flavor> \
--nic net-id=<net1-id> --nic net-id=<net2-id> <vm-name>

BUT if you look at the description of the network object in the API abstraction it looks like a collection of subnets (meaning the quantum object), so basically a collection of IP Addresses like 192.168.100.0/24

SO (first question): what happens in the network where I boot the VM has more than a subnet?...I suppose the VM should have a nic for EACH subnet of the network!

THEN (second question): why do I need a network object? Shouldn't it be more practical to have just the subnet object?..why do I need to create a Network if it's just a collection of subnets?

Thanks in advance for any help

Best Regards

Marco
