First of all,

With the latest releases of ODA, here is a quick info;

With ODA 19.10 release, only 19.10 database is supported in DB Systems
With ODA 19.11 release, only 19.11 database is supported in DB Systems
With ODA 19.12 release, only newly provisioned 19.12 and 21.3 databases are supported in DB Systems.

The supported database version for a given DB System version can be queried using odacli describe-dbsystem-image

Ref: Oracle Database Appliance (ODA) - KVM FAQ

You will use KVM for the virtualization.
As for the DB and APPS server, you will have DB Systems (Basically a vm with a db) and application Vms (simple VMs with Oracle Linux).

There are some restrictions that will make you align yourself;

->
All virtual machines (VM), or guests, are Oracle Linux operating systems and only Linux applications are supported in the KVM.
You cannot deploy an Oracle Database in the KVM. Oracle Databases must run on the base Oracle Linux operating system.   (this may be misleading .. We have a thing called DB System now..)

Check : https://blogs.oracle.com/oda/post/oracle-database-appliance-oda-kvm-faq
As for the DB system (including the fileysystems as well) and application vms, these tasks are highly automated in this machine, please have a look at the following blog post;
