 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.

 David
