Hi Thierry: We didn't have this use case in mind when we did our initial implementation of heterogeneous instance types, but it's an interesting idea and should be pretty straightforward to implement (says the guy at ISI who probably contributed the least amount of code to the heterogeneous implementation...). Is there community interest in this type of functionality?

Re: [Openstack] heterogeneous instance types
That is a good idea if the networking service supports it. One of the things we've been thinking about is how to best to make the virt subsystem more modular. It really needs a better driver-style interface with plugins for non-libvirt virts, I think. Mikyung actually had to build a bare metal TFTP-boot image management system for the Tilera system because it doesn't currently support KVM or Xen. I could see some HPC folks interested in managing bare-metal XCAT or Perceus machines.

Re: [Openstack] heterogeneous instance types
Brian, nice spec! It's a great example of why I appreciate detailed blueprints. Although I think it's very interesting to store more information about instance types, I'd be more cautious in creating new columns if it's not strictly necessary. I'd prefer a metadata table, something similar to the instance_metadata table. In this way, each provider can adjust the attributes to their real needs or imagination :) - Ferdy ___ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
