Hi Mandar, The whole "default" stuff is a common point of confusion with QuantumManager, and something we're planning on getting rid of in Folsom. For Essex, I've explained the details below.

Hence, from a Quantum perspective that network does not have a tenant, making this a "global" network, which is owned by a tenant named "default" (this string can be changed using the quantum_default_tenant_id flag in nova). For more details on creating quantum networks with nova-manage, see: http://docs.openstack.org/incubation/openstack-network/admin/content/Net-Create-dle455.html > **** > > BTW, stack.sh creates incorrect entries in quantum/mélange DB, it has > tenant ID = “default” – This should be uuid of some valid tenant, not > string “default” > This is not actually incorrect, given the logic above, though I admit it is confusing. This was really just to provide backward compatibility with old nova-manage calls that did not specify a project. In Folsom, we're planning on requiring a tenant for all Quantum network creation. > **** > > ** ** > > FWIW, this setup (although seems incorrect) works with quantum+nova_ipam – > not with quantum+mélange **** > > i.e. With quantum+nova_ipam I can just create a VM and ssh to it. > Yes, quantum + nova-ipam is a much more tested path. I suspect you are just running into the bug I mention below and that your quantum + melange setup would work once you have that patch in, but I don't know of anyone using Melange + DHCP in a real deployment, so I wouldn't be surprised if there were more issues lurking.
