Although this seems a little bit confident, the long-awaited Update 6 to the Solaris 10 operating system release is just behind the door. This release (scheduled to be available in mid-October) will “includes virtualization enhancements including the ability for a Solaris Container to automatically update its environment when moved from one system to another, Logical Domains support for dynamically reconfigurable disk and network I/O, and paravirtualization support when Solaris 10 is used as a guest OS in Xen-based environments such as Sun xVM Server. Solaris 10 10/08 also includes support for the latest systems from Sun and other vendors, such as those based on the Intel Xeon Processor 7400 Series”.
This release will be the very first Solaris release to be able to boot from ZFS and use it as their root file system, such as what can be found on OpenSolaris or Solaris Express Community Release today.
