The following Oracle VM Server for SPARC features are deprecated in this release of the software and might be removed from the product at any time:
The network interface functionality of an Oracle VM Server for SPARC vsw driver was deprecated in Oracle Solaris 11.1. The Oracle VM Server for SPARC vsw driver continues to provide virtual network switching functionality for guest domains. See Oracle Solaris 11 Networking Overview in Oracle VM Server for SPARC 3.1 Administration Guide.
Setting the threading property to max-ipc to manage single-thread workloads on SPARC T4 platforms is deprecated. By default, domains are created for maximum throughput, and the Oracle Solaris OS automatically uses the critical thread API to optimize for single-thread workloads.
Using the –c option of the add-vcpu, set-vcpu, and rm-vcpu subcommands to manage hard partitioning is deprecated. Instead, use the add-core, set-core, or rm-core subcommand to assign whole cores. Also, use the add-domain or set-domain subcommand to specify the CPU cap (max-cores).
Using the Hybrid I/O feature is deprecated in favor of using the single-root I/O virtualization (SR-IOV) feature.
Migrations of domains that run an Oracle Solaris OS older than Oracle Solaris 10 9/10 are referred as “uncooperative” migrations. The live migration feature has deprecated the use of the uncooperative migration feature. In the future, these types of migrations might be explicitly rejected. Therefore, ensure that the guest domain runs at least the Oracle Solaris 10 9/10 OS or Oracle Solaris 11 OS.
