LDoms Solaris patches available since Solaris 10 8/07 (S10U4) was released

There have been a number of LDoms fixes backported to S10 since Solaris 10 8/07 (S10U4) was released[\*]. They are available in the S10 Sustaining KU, 127111 and can be applied to Solaris 10 8/07 (S10U4) or Solaris 10 11/06 (S10U3). In fact, instead of applying 124921-02 which was released at the same time as LDoms 1.0, it is recommended to use the latest revision of the 127111 patch with S10U3 as many more bug fixes are available via 127111 and 120011-14 (the S10U4 KU patch that 127111 depends on).

 

[ Updated 2008-02-07: Added  127111-08 ]

The fixes include improvements to vDisk support for rebooting control/service domains, guest networking performance enhancements as well as fixing the way LDoms/OBP variables are stored while rebooting a domain. In addition, a fix for the vsw issue that Narayan describes is included.

About

I have been working in Sun/Oracle since 1998 and I've spent much of that time working on adding Solaris support for various SPARC processors and servers. For the last 6+ years I've been working on what is now known as Oracle VM Server for SPARC (previously called LDoms) – virtualisation support for servers based on UltraSPARC CMT processors.
