Logical Domains (LDoms) 1.1 README

I thought it would be useful to post the LDoms 1.1 README. It contains useful information for documentation and required software, especially required System Firmware for supported servers.

This is the Logical Domains (LDoms) 1.1 README included in the zip download file:

This download also contains the SUNWjldm.v package, which installs
the localized Japanese man page for the ldm(1M) command.
Japanese locales supported: ja, ja_JP.eucJP, ja_JP.PCK, ja_JP.UTF-8
This package is found in the Product/Japanese directory.


Software
========

In order to avail of all the features in LDoms 1.1, the Operating System on all
domains should be equivalent to Solaris 10 10/08 at a minimum. This can either
be a fresh/upgrade install of Solaris 10 10/08 or any of Solaris 10 5/08,
Solaris 10 8/07 or Solaris 10 11/06 with 137137-09 applied.

In addition, the patches listed below are required. It lists what types of
domain each patch is required to be applied to but the patches can be applied
to all domains.

Patch                              Control      Service/IO      Guest
                                   Domain       Domain          Domain
139562-02 (multiple LDoms drivers)   X            X               X
139570-02 (nxge driver)              X            X               X
139508-01 (niumx driver)             X            X               X
139502-01 (picl plugin)              X
139458-01 (aggr driver)              X            X


Following is a matrix of required software to enable all the
Logical Domains 1.1 features:

Supported Servers               System Firmware    Solaris OS

Sun UltraSPARC T2 Plus-based    7.2                One of the configs above
Sun UltraSPARC T2-based         7.2                One of the configs above
Sun UltraSPARC T1-based         6.7                One of the configs above

It is possible to run the Logical Domains 1.1 software along with previous
revisions of the other software components. For example, you could have
differing versions of the Solaris OS on the various domains in a machine.
It is recommended to have all domains running Solaris 10 10/08 OS plus
patches listed above, but an alternate upgrade strategy could be to upgrade
the control and service domains to Solaris 10 10/08 OS plus patches list above
and to continue running the guest domains at the existing patch level.

Following is a matrix of the minimum version of software required.
The minimum software versions are platform specific and depend on the
requirements of the CPU in the machine. The minimum Solaris OS version for a
given CPU type applies to all domain types (control, service, I/O, and guest).

Supported Servers               System Firmware         Solaris OS

Sun UltraSPARC T2 Plus-based    7.1.x                   Solaris 10 8/07(1)
Sun UltraSPARC T2-based         7.0.x                   Solaris 10 8/07
Sun UltraSPARC T1-based         6.5.x                   Solaris 10 11/06(2)

(1) Must also use Patch ID 127111-08 at a minimum
(2) Must also use Patch IDs 124921-02, 125043-01, and KU 118833-36 at a minimum


Sun System firmware available on http://sunsolve.sun.com


The Libvirt and MIB software for LDoms 1.0.1 also supports LDoms 1.1.

In addition to the software packages for Libvirt and virt-install,
the source is included in this download.
The Libvirt source can be found in the Product/Libvirt-source directory.
The virt-install source and the binaries are the same.
Here are the default locations for the virt-install files:
        /usr/lib/python2.4/vendor-packages/urlgrabber/__init__.py
        /usr/lib/python2.4/vendor-packages/urlgrabber/byterange.py
        /usr/lib/python2.4/vendor-packages/urlgrabber/grabber.py
        /usr/lib/python2.4/vendor-packages/urlgrabber/keepalive.py
        /usr/lib/python2.4/vendor-packages/urlgrabber/mirror.py
        /usr/lib/python2.4/vendor-packages/urlgrabber/progress.py
        /usr/lib/python2.4/vendor-packages/urlgrabber/sslfactory.py
        /usr/lib/python2.4/vendor-packages/virtinst/DistroManager.py
        /usr/lib/python2.4/vendor-packages/virtinst/FullVirtGuest.py
        /usr/lib/python2.4/vendor-packages/virtinst/Guest.py
        /usr/lib/python2.4/vendor-packages/virtinst/Makefile
        /usr/lib/python2.4/vendor-packages/virtinst/ParaVirtGuest.py
        /usr/lib/python2.4/vendor-packages/virtinst/__init__.py
        /usr/lib/python2.4/vendor-packages/virtinst/util.py
        /usr/sbin/virt-install


Flag-Day for configurations

Existing LDoms 1.0 configurations do not work in LDoms 1.1 software.
See the "Upgrading to LDoms 1.1 Software" section in the Logical Domains
