Creating a Dedicated Virtual Machine Host

You must create a dedicated virtual machine host in Compute before you can place any instances on it.

When creating a dedicated virtual machine host, you select an availability domain and fault domain to launch it in. All the VM instances that you place on the host are subsequently created in this availability domain and fault domain.

You also select a compartment when you create the host, but you can move the host to a new compartment later without impacting any of the instances placed on it. You can also create the instances in a different compartment than the host, or move them to different compartments after they have been launched.
