You must reboot the control domain for the configuration changes to take effect and for the resources to be released for other logical domains to use.
primary# shutdown -y -g0 -i6
Note - Either a reboot or power cycle instantiates the new configuration. Only a power cycle actually boots the configuration saved to the service processor (SP), which is then reflected in the list-config output.
Note - This procedure contains examples of resources to set for your control domain. These numbers are examples only, and the values used might not be appropriate for your control domain.
Note that only UltraSPARC T2, UltraSPARC T2 Plus, and SPARC T3 platforms have cryptographic devices (MAUs). Because newer platforms, such as SPARC T4 systems and Fujitsu M10 systems, do not have separate cryptographic units, there is no need to assign a cryptographic accelerator on these platforms.
primary# ldm list -o crypto primary
The following example would assign one cryptographic resource to the control domain, primary. This leaves the remainder of the cryptographic resources available to a guest domain.
primary# ldm set-mau 1 primary
For example, the following command would assign 8 virtual CPUs to the control domain, primary. This leaves the remainder of the virtual CPUs available to a guest domain.
primary# ldm set-vcpu 8 primary
Initiate a delayed reconfiguration on the control domain.
primary# ldm start-reconf primary
For example, the following command would assign 4 gigabytes of memory to the control domain, primary. This leaves the remainder of the memory available to a guest domain.
primary# ldm set-memory 4G primary
For example, the following command would add a configuration called initial.
primary# ldm add-config initial
primary# ldm list-config
factory-default
initial [current]
This ldm list-config command shows that the initial configuration set will be used after you perform a power cycle.
The following virtual device services must be created to use the control domain as a service domain and to create virtual devices for other domains:
vcc – Virtual console concentrator service
vds – Virtual disk server
vsw – Virtual switch service
For example, the following command would add a virtual console concentrator service (primary-vcc0) with a port range from 5000 to 5100 to the control domain (primary).
primary# ldm add-vcc port-range=5000-5100 primary-vcc0 primary
For example, the following command adds a virtual disk server (primary-vds0) to the control domain (primary).
primary# ldm add-vds primary-vds0 primary
Assign a GLDv3-compliant network adapter to the virtual switch if each logical domain must communicate outside the box through the virtual switch.
In Oracle Solaris 10, add a virtual switch service on network adapter driver to the control domain.
primary# ldm add-vsw net-dev=net-driver vsw-service primary
For example, the following command adds a virtual switch service (primary-vsw0) on network adapter driver nxge0 to the control domain (primary):
primary# ldm add-vsw net-dev=nxge0 primary-vsw0 primary
In Oracle Solaris 11, add a virtual switch service (primary-vsw0) on network adapter driver net0 to the control domain (primary):
primary# ldm add-vsw net-dev=net-driver vsw-service primary
For example, the following command adds a virtual switch service (primary-vsw0) on network adapter driver net0 to the control domain (primary):
primary# ldm add-vsw net-dev=net0 primary-vsw0 primary
The following applies to the Oracle Solaris 10 OS only and should not be performed on an Oracle Solaris 11 system.
This command automatically allocates a MAC address to the virtual switch. You can specify your own MAC address as an option to the ldm add-vsw command. However, in that case, it is your responsibility to ensure that the MAC address specified does not conflict with an already existing MAC address.
If the virtual switch being added replaces the underlying physical adapter as the primary network interface, it must be assigned the MAC address of the physical adapter, so that the Dynamic Host Configuration Protocol (DHCP) server assigns the domain the same IP address. See Enabling Networking Between the Control/Service Domain and Other Domains.
primary# ldm add-vsw mac-addr=2:04:4f:fb:9f:0d net-dev=nxge0 primary-vsw0 primary
Your output should look similar to the following:
primary# ldm list-services primary
VDS
NAME VOLUME OPTIONS DEVICE
primary-vds0
VCC
NAME PORT-RANGE
primary-vcc0 5000-5100
VSW
NAME MAC NET-DEV DEVICE MODE

If you remove the Logical Domains Manager before restoring the factory default configuration, you can restore the factory default configuration from the service processor.
-> set /HOST/bootmode config=factory-default
-> reset /SYS
After restoring the factory default configuration and disabling the Logical Domains Manager, you can remove the Logical Domains Manager software.
Note - If you remove the Logical Domains Manager before restoring the factory default configuration, you can restore the factory default configuration from the service processor as shown in the following procedure.
primary# pkgrm SUNWldm SUNWldmp2v
primary# pkg uninstall ldomsmanager
primary# ldm stop-domain -a
primary# ldm unbind-domain ldom
Note - You might be unable to unbind an I/O domain if it is providing services required by the control domain. In this situation, skip this step.
primary# ldm remove-domain -a
primary# ldm list-config
Use the following command for each such configuration:
primary# ldm rm-config config-name
After you remove all the configurations previously saved to the SP, the factory-default domain is the next domain to use when the control domain (primary) is rebooted.
primary# ldm set-config factory-default
primary# shutdown -i1 -g0 -y
-> stop /SYS
-> start /SYS
primary# svcadm disable ldmd
Note - Disabling the Logical Domains Manager does not stop any running domains, but does disable the ability to create a new domains, change the configuration of existing domains, or monitor the state of the domains.
Use this procedure to enable the ldmd daemon if it has been disabled.
For more information about the svcadm command, see the svcadm(1M) man page.
# svcadm enable ldmd
The ldm list command should list all domains that are currently defined on the system. In particular, the primary domain should be listed and be in the active state. The following sample output shows that only the primary domain is defined on the system.
# /opt/SUNWldm/bin/ldm list
NAME STATE FLAGS CONS VCPU MEMORY UTIL UPTIME
primary active ---c- SP 64 3264M 0.3% 19d 9m
