vm migration between zones

[Ivan Derbenev <iv...@tech-corps.com>]

Hello guys, I am deploying cloudstack 4.2 with XenServer 6.2

For now I have a problem. We have 2 datacenters, each would be in its own zone (or region, we haven't decided yet).
So...

1)      Can we have different mysql databases, for management servers in each datacenter? Without replication between each other? Because management server in first datacenter doesn't really need to know anything about second DC's hosts\vms\etc.

But in the same time it would be great if I could login any of management servers in each DC and get access to any zone.

So the question is - can we connect two datacenters without database replication over internet?


2)      The only thing we really need from this connection is the ability to migrate instances from one datacenter to another. But I could't find any way how to migrate instance between zones\regions, or just export and import it. Is it really possible to do that or it can be done inside clusters only?

Regards,
Ivan Derbenev

Ivan,

If you want effectively two independent Data Centers, then simply make each DC a Zone within its own Region.  This way you will have two independent 'Clouds' but will be able to share login information and switch between the Regions with a single login etc.

It is not possible (yet) to 'migrate' VMs between different Zones or Regions so you would need to export the VM from one Zone, and then import it into the other Zone.
