New Zones Features

Jeff Victor's article on New Zones Features describes many of the Zones related enhancements to Solaris 10 8/07. Jeff describes how to:
  • Set a physical memory cap on a Container
  • Cap Virtual memory (i.e. swap space)
  • Set locked memory (i.e. prevent from being paged out) limits
  • Dedicate CPUs to a zone
  • Set shared memory, and ids for shared memory, semaphores and message queues by Container
  • Use the Fair Share Scheduler to simply assign cpu-shares to a zone
  • Assign DTrace privileges, dtrace_proc and dtrace_user to a Container
  • Grant exclusive access to one or more network interfaces to a Container
  • Set up Container to Container communication via an external box
  • Upgrade and Patch Containers with Live Upgrade
