Hi, There is valid concern about the upgrade procedure with this patch. There is a way that we are able to do this without creating an major problems: 1. Leave the class QuantumLinuxBridgeVIFDriver unchanged 2. Add in a new class QuantumLinuxBridgeVIFDriverEnhanced (or if someone has a better name). This class will contain the changes. If someone wants to benefit fro the changes then she/he will need to update their configuration file to:
libvirt_vif_driver=nova.virt.libvirt.vif.QuantumLinuxBridgeVIFDriverEnhanced This can be documented and it may treat all of the concerns. Naturally a patch upstream will need to be added so that this wil be forward compatible.
Yeah, I think this would work well - linuxbridge users are no longer required to update Quantum before Nova, they just need to update Quantum before using the new VIF driver. So, yep - go for it IMHO. It'll have to wait until after 2012.2.1 though and will have to happen on master too. Cheers, Mark.
