https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=230330 --- Comment #11 from Mark Millard <marklmi26-fbsd@yahoo.com> --- (In reply to Jan Beich from comment #8) I had to look up what a Solaris Zone is: "A zone is a virtualized operating system environment created within a single instance of the Solaris OS." And: "Oracle Solaris Zones, previously known as Solaris Containers, are an integral part of the Oracle Solaris 10 operating system (OS). Zones isolate software applications and services using flexible software-defined boundaries. You can use zones to create private execution environments within a single instance of the Oracle Solaris 10 OS. Each environment has its own identity that is separate from the underlying hardware. Each environment behaves independently as if running on its own system, making consolidation simple, safe, and secure." Looking at the implementation referenced, unless one deliberately creates an whole "virtualized operating system environment", one does not get zone results. It looks to me like processor_affinity, for example, is available for both in-a-zone and not-in-a-zone styles of use. This affinity does not seem to contribute to the results for _SC_NPROCESSORS_ONLN or _SC_NPROCESSORS_CONF . So, a more complicated analogy to form in trying to compare Solaris. -- You are receiving this mail because: You are the assignee for the bug.
