Oracle Exadata and OVM. Exadata VM Usage •VMs on Exadata focused on Database Consolidation •ExadataVMs can only run certified Oracle Linux versions. This chapter provides the information needed to administer your Oracle Exadata Database Machine through Oracle Enterprise Manager Cloud Control 13c. The following. Application owners went in two directions, 1) maintained the status quo of Oracle on UNIX, and 2) replatform Oracle on Oracle Exadata (Sun x86 hardware with Oracle.
Mark, I am with you, a snob and a purist. The Oracle database has been developed for multi-tenancy and does it well. It has _for years_. I think the limiting factor is still the hardware layer. But ok, maybe regulatory compliance.
A separate Oracle home and independent resources usually does the trick for me. Yamaha Keyboard Song. Having said that, I am an Oracle Exadata Sales Consultant, so I encourage customers to create their virtualized database architectures with great care, whether they are on Engineered Systems or not.

Next ptifall is, that connecting your ZFS appliance or Media Server via Infiniband is only supported on Bare Metal. Those two things should be considered, when evaluating the usage of OVM.
In most cases for sizings like an Eigth Rack or Quarter Rack, you might be better off cost wise with one or two ODA X-5 systemes or generic x86 iron plus NVMe drives plus FlashGrid, especially if you are running mainly OLTP workloads, since all the offloading magic is designed mainly for DWH. If you want a truly working Exadata, I personally would recommend at least adding 3rd database Server and IB-switch, so we can have a failure of a database server, switch and storage cell and still be redundant. Then we can call this an enterprise solution. Stay away from entry level solutions with only 2 db servers and OVM on top, as the stack is still new, adds alot of layers and further increases complexity of management (Dom0, Grid Disk partitioning, VM-Cluster, Grid Infrastructure Cluster) and limitations.
