[one-users] question about System Datastore on Opennebula 3.4

[Ruben S. Montero]

Hi,

The only problem here
Hi,

There are some considerations in this case:

1.- The VMs will not be able to migrate (nor live nor cold) across
datacenters. You can't also stop a VM in a Datacenter, and resume it
in the other
2.- Both datacenters must have access to the image datastores used by
the VMs (e.g. through SSH or a shared NFS server...)

Apart from that ones, there should not be any problem. You may be
interested in creating two clusters for each datacenter and then use
it as a REQUIREMENT for the VMs. (If you also assign
datastores/networks to the datacenters, the REQUIREMENTS would be
automatically generated by OpenNebula)

Cheers

Ruben
