Solaris 10 What's New

System Resource Enhancements

The following system resource features and enhancements have been added to the Solaris 10 11/06 release.

Resource Management Features

The following resource management features and enhancements have been added to the Solaris 10 11/06 release.

Resource Pools Facility Service FMRIs

Resource pools and dynamic resource pools have been integrated into the Solaris service management facility (SMF). Dynamic resource pools are now enabled separately of the resource pools service.

The dynamic resource pools service fault management resource identifier (FMRI) is svc:/system/pools/dynamic. The resource pools service FMRI is svc:/system/pools.

The enabling and disabling mechanisms through pooladm(1M) are still available.

Note –

When a system is upgraded, if a /etc/pooladm.conf file exists, the configuration contained in the file is applied to the system.

Solaris Zones Features

The following Solaris zones features and enhancements have been added to the Solaris 10 11/06 release.

Solaris Zones Renaming Feature

The zone name is now an attribute that can be set through the zonecfg command. Only zones in the configured or installed states can be renamed.

For information about zones configuration and zone states, see:

System Administration Guide: Solaris Containers-Resource Management and Solaris Zones
zonecfg(1M) man page
zones(5) man page

Zones Move and Clone Features

Two new subcommands, move and clone, have been added to the zoneadm command. You can now do the following:

Relocate a non-global zone from one point on a system to another point on the same system
Rapidly provision a new non-global zone based on the configuration of an existing zone on the same system

For more information, see:

Migrating a Non-Global Zone From One Machine to Another

The zonecfg and zoneadm commands have been modified to enable you to migrate a non-global zone from one system to another. The procedure used detaches a halted zone from its current location, and attaches the zone at a new location. The global zone on the target system must be running the following:

The same release as the original host
The same versions of operating system packages and patches as the original host

The zone detach process creates the information necessary to attach the zone on a different system. The zone attach process verifies that the new machine has the correct configuration to host the zone. You can make the zonepath available on the new host in several ways. Therefore, the actual movement of the zonepath from one system to another is a manual process that is performed by the zone administrator.

When attached to the new system, the zone is in the installed state.

zoneadm(1M) man page

Configurable Privileges for Non-Global Zones

The limitpriv property of the zonecfg command can be used to specify the set of privileges that processes are limited to in a non-global zone.

You can do the following:

Augment the default set of privileges with the understanding that such changes might allow processes in one zone to affect processes in other zones by being able to control a global resource
Create a zone with fewer privileges than the default, safe set

For more information about configuring privileges for zones and zone privilege restrictions, see:

Note –

Note the following:

Non-global zones are still booted with the standard set of safe privileges by default.
One set of privileges cannot be removed from the zone's privilege set, and another set of privileges cannot be included in the zone's privilege set

Logical Domains Features

The following logical domains features and enhancements have been added to the Solaris 10 11/06 release.

Logical Domains (LDoms) 1.0 Software

The Logical Domains (LDoms) 1.0 software enables system administrators to create and manage logical domains. This software provides multiple software partition support and the following features for Sun4v-based platforms:

Software upgrade to UltraSPARC T1 systems (Solaris 10 11/06 and firmware upgrade)
Up to 32 logical domains per system, managed by a CLI, the Logical Domains (LDoms) Manager 1.0 software, which is a separate download
Each guest domain can be created, destroyed, reconfigured, and rebooted independently
Virtual console, Ethernet, disk, and cryptographic acceleration
Live dynamic reconfiguration of virtual CPUs
Fault management architecture (FMA) diagnosis for each logical domain

In addition to the Solaris 10 11/06 OS, a minimum level of system firmware 6.4 and Logical Domains Manager 1.0 software is required to have Logical Domains functionality.
