8.14.7 Configuring the CPU Socket Constraints to the Logical Domain Configuration
The following example describes how to create the logical domain ldom1 which owns 16 GB mirrored memory and 8 CPU cores that are associated with CPU socket #4.
Use the ldm add-domain command to create the logical domain ldom1.
primary# ldm add-domain ldom1 |
Use the ldm set-socket command to constrain ldom1 to use the resources that are associated with CPU socket#4.
primary# ldm set-socket socket_id=4 ldom1 |
Allocate 8 CPU cores and 16-GB memory to ldom1.
primary# ldm set-core 8 ldom1 primary# ldm set-memory 16G ldom1 |
Bind the resources to ldom1 and start ldom1.
primary# ldm bind-domain ldom1 primary# ldm start-domain ldom1 |
Note - To bind and start the logical domain, you should prepare a virtual console concentrator, a virtual network switch, and a virtual disk service. For details on each item, see the Oracle VM Server for SPARC Administration Guide of the version used. |
Use the ldm list-socket command to show the list of the resources of each CPU socket.
You can confirm only the resources that are associated with CPU socket #4 are assigned to ldom1.
You can confirm only the resources that are associated with CPU socket #4 are assigned to ldom1.
# ldm list-socket ldom1 CONSTRAINTS DOMAIN SOCKET_ID STATE ldom1 4 active SOCKET TENANT VCPUS CORES SOCKET_ID GROUP ldom1 16 8 4 /BB1 MEMORY PA SIZE SOCKET_ID BOUND 0x760050000000 16G 4 ldom1 IO |
Figure 8-5 shows the physical partition configuration after the ldm set-socket command is executed in the physical partition configured with two SPARC M10-4S units (BB#0 and BB#1).
