We're thrilled to announce the release of LDoms 3.4 (officially
Oracle VM Server for SPARC 3.4), which has been delivered as part
of Oracle Solaris 11.3 SRU 8.7. Together, they provide new features
for virtualization, performance, security, scalability, and system
management.
Rather than repeating what others have said, I'll just direct
you to these two blog entries
