[Fiware-lab-federation-nodes] Migration Plan After Open Call Results

[Cristian Cristelotti]

Same for us in Trento.

We've done a little script to save all VMs, transfer the snapshots and create the commands (glance image-create ... )  to launch the snapshots on the new node.

Dear Fernando,all 
since we are in the process of migrating our vm's to other nodes can we have any tips on how to do that more efficiently? 
I believe the process should be to create a snapshot and then tranfer the snapshot to the new node glance??? 

RKE : Yes this is how in Lannion we had proceed for Juno and will proceed for Kilo. 

Will we be able to transfer our images directly to other node glance servers? 

RKE: I think you should ask to Fernando to put your new node in the config of the “automatic image update tool”. 



Thanks a lot in advance, 
Fanis

Dear Fernando, 
i tried the proposed solution and it failed again. 
I then noticed it tries to load OpenstackMap module which in the skuld 
folder is called as OpenStackMap. 
Changed in users.py line 48 the name to OpenStackMap and it worked. 
However now i get this: 

Getting administrator token... 
Getting id of the requested region... 
Getting the list of projects in the specific region... 
Get the list of users with some role on those projects... 
Getting the email of the identified users... 
Making analysis bottom-up...
