Dynamic reconfiguration (DR) enables resources to be added or removed while the operating system (OS) is running. The capability to perform DR of a particular resource type is dependent on having support in the OS running in the logical domain.
Dynamic reconfiguration is supported for the following resources:
Virtual CPUs – Supported in all versions of the Oracle Solaris 10 OS and the Oracle Solaris 11 OS
Virtual I/O devices – Supported in at least the Oracle Solaris 10 10/08 OS and the Oracle Solaris 11 OS
Cryptographic units – Supported in at least the Oracle Solaris 10 1/13 OS and the Oracle Solaris 11 OS
Memory – See Using Memory Dynamic Reconfiguration
CPU whole cores – See Fully Qualified Oracle Solaris OS Versions in Oracle VM Server for SPARC 3.2 Installation Guide
Physical I/O devices – Not supported
To use the DR capability, the Logical Domains DR daemon, drd, must be running in the domain that you want to change. See the drd(1M) man page.
