i got over 10 Servers spread over multiple sites. and i wanted to set u a private cloud on them. Im not that experienced but i got an older installation of openstack and an openstack juno devstack clone running.

my question is can i use the devstack guide ( http://docs.openstack.org/developer/devstack/guides/multinode-lab.html (http://docs.openstack.org/developer/d...) ) for setting it up the fast way or will i face a ton of difficulties, doing it and should install everything manually?

would it be possible to transfer VMs between sites?

do you have additional suggestions, how maybe you would set this hole thing up?

kind regards and a big THX in advance

Question - Do you expect this to be production level? If so then no, do not use Devstck. If you are just testing out and want to connect them together via Multi-node you could try but it shouldn't be a production environment.

Devstack isn't considered to be production. For production you need to check out the ops guide and figure out a HA setup and what will take advantage of your BW the most, as in putting certain services together in one DC and have others located remote, or have really small images.

Thomas, you mentioned this 'i wanted to set u a private cloud on 10 servers'. Go with manual installation i think it is better choice to maintain a private cloud and it will take Max 10hrs of time to configure.

It should be possible to transfer VMs between compute nodes.

IMO, if you want to setup a multi-region private cloud using OpenStack just for learning and research, you can use devstack to do that. refer to my settings in this question https://ask.openstack.org/en/question...

if you want to setup for production level , you can take a look at cloud configuration tools like Chef, Puppet, SaltStack, just google them.

As for vm migration between regions, you might do that with very strict environment setup however, find more details in OpenStack operation guide please.

Hope that helps!

Vic
