About Oracle Solaris 10 Zones in This Release

Operating Limitations of Oracle Solaris Zones

A /dev/sound device cannot be configured into the solaris10 branded zone.

The file-mac-profile property used to create read-only zones is not available.

The quota command documented in quota(1M) cannot be used to retrieve quota information for UFS file systems being used inside the solaris10 branded zone.

A solaris10 branded zone cannot be an NFS server.

An automounter in a solaris10 branded zone does not support the NIS+ naming service.

Networking in Oracle Solaris 10 Zones

The following sections identify Oracle Solaris 10 networking components that are either not available in Oracle Solaris 10 Zones or that are different in Oracle Solaris 10 Zones.

Unsupported Networking Components in Oracle Solaris 10 Zones

  • Automatic tunnels using the atun STREAMS module are not supported.

  • The following ndd tunable parameters are not supported in a solaris10 branded zone:

    • ip_squeue_fanout

    • ip_soft_rings_cnt

    • ip_ire_pathmtu_interval

    • tcp_mdt_max_pbufs

Networking Features That Are Different in Oracle Solaris 10 Zones

In a solaris10 branded zone with an exclusive-IP configuration, the following features are different from a physical Oracle Solaris 10 system:

  • Mobile IP is not available because it is not available in the Oracle Solaris 11 release.

  • In a solaris10 branded zone, an autopush configuration will be ignored when the tcp, udp, or icmp sockets are open. These sockets are mapped to modules instead of STREAMS devices by default. To use autopush, explicitly map these sockets to STREAMS-based devices by using the soconfig and sock2path.d utilities described in the soconfig(1M) and sock2path.d(4) man pages.

  • In a solaris10 branded zone archived from a physical system running Oracle Solaris 10 9/10 or an earlier update, /dev/net links, such as VNICs, are not supported by the Data Link Provider Interface library (libdlpi). These links are supported on Oracle Solaris 10 8/11. The library is described in thelibdlpi(3LIB) man page.

    Applications that do not use either the libdlpi library in Oracle Solaris 10 8/11 or libpcap versions 1.0.0 or higher libraries will not be able to access /dev/net links, such as VNICs.

  • Because IP Network Multipathing (IPMP) in Oracle Solaris 10 Zones is based on the Oracle Solaris 11 release, there are differences in the output of the ifconfig command when compared to the command output in the Oracle Solaris 10 operating system. However, the documented features of the ifconfig command and IPMP have not changed. Therefore, Oracle Solaris 10 applications that use the documented interfaces will continue to work in Oracle Solaris 10 Zones without modification. All of the standard Oracle Solaris 10 networking facilities, such as ifconfig and /etc/hostname.name, should be used to configure and use IPMP and perform all other network configuration.

    The following example shows ifconfig command output in a solaris10 branded zone for an IPMP group ipmp0 with data address and the underlying interfaces e1000g1 and e1000g2, with test addresses and, respectively.

    $ ifconfig -a
    mtu 1500 index 8
            inet netmask ffffff00 broadcast
            ether 0:11:22:45:40:a0
    mtu 1500 index 9
            inet broadcast
            ether 0:11:22:45:40:a1
    ipmp0: flags=8011000803<UP,BROADCAST,MULTICAST,IPv4,FAILED,IPMP> mtu 68 
    index 10
            inet netmask ffffff00 broadcast
            groupname ipmp0
    • Unlike the display produced on an Oracle Solaris 10 system, the ifconfig command in an Oracle Solaris 10 Container does not show the binding of the underlying interfaces to IP addresses. This information can be obtained by using the arp command with the –an options.

    • If an interface is plumbed for IPv6 and address configuration succeeds, then the interface is given its own global address. In an Oracle Solaris 10 system, each physical interface in an IPMP group will have its own global address, and the IPMP group will have as many global addresses as there are interfaces. In a Oracle Solaris 10 Zones, only the IPMP interface will have its own global address. The underlying interfaces will not have their own global addresses.

    • Unlike the Oracle Solaris 10 operating system, if there is only one interface in an IPMP group, then its test address and its data address cannot be the same.

    • For information on configuring an IPMP group in a solaris10 zone in an Oracle Solaris Zones cluster, refer to the Oracle Solaris Cluster 4.1 Release Notes.
