[openstack-dev] opnfv proposal on DR capability enhancement on OpenStack Nova

Zhipeng Huang,
When multiple  Datacenters are interconnected over WAN/Internet if the remote the Datacenter goes down, expect the 'native VM status' to get changed accordingly ?
Is this the requirement ? This requirement is  from NFV Service VM (like routing VM ? )
Then is not it is  NFV routing (BGP/IGP) /MPLS signaling (LDP/RSVP) protocol to handle  ? Does the OpenStack needs to handle that ?

Please correct me if my understanding on this problem  is not correct.

Thanks & regards,

Hi Zhipeng,

I would just like to echo the comments from the opnfv-tech-discuss list (which I notice is still private?) in saying that there is very little detail on the wiki page describing what you actually intend to do. Given this, it's very hard to provide any meaningful feedback. A lot more detail is required, particularly if you intend to propose a specification based on this idea.
