This is very interesting problem to solve. I am curious to know how the reachability is provided across different Datacenter. How to know which VM is part of which Datacenter? VM may be in different Zone but under same DC or in different DC itself. How this problem is solved? thanks & regards, keshava -- View this message in context: http://openstack.10931.n7.nabble.com/all-tc-Multi-clouds-integration-by-OpenStack-cascading-tp54115p56323.html Sent from the Developer mailing list archive at Nabble.com.
