Victor,
You raised a very good point. If you want to use any existing flag, what Razique said is OK. But if you want to add new key value pairs, I don't think the current nova-compute can do that. Especially if you are using the currnent nova/virt/libvirt as compute driver, you cannot. In our bare-metal provisioning effort, our compute driver nova/virt/bm defines a new flag called "instance_type_extra_specs" in /etc/nova/nova.conf. Any key value pairs can be specified there. For example, for TileEmpower board we declare the flag as follows: instance_type_extra_specs=cpu_arch:tilepro64 Our bare-metal provisioning code is still in review.
