** Changed in: nova Status: Invalid => In Progress ** Changed in: nova Assignee: (unassigned) => Nicolas Simonds (nicolas.simonds) -- You received this bug notification because you are a member of Yahoo! Engineering Team, which is subscribed to OpenStack Compute (nova). https://bugs.launchpad.net/bugs/1156456 Title: libvirt CPU info doesn't count NUMA cells Status in OpenStack Compute (nova): In Progress Bug description: The libvirt driver, when counting sockets/cores/etc., does not take NUMA architectures into account. This can cause applications using data from the Nova API to under-report the total number of sockets/cores/etc. on compute nodes with more than one NUMA cell. Example, on a production system with 2 NUMA cells: $ grep ^proc /proc/cpuinfo | wc -l 32 $ python simple_test_script_to_ask_nova_for_cpu_topology.py {u'cores': u'8', u'threads': u'2', u'sockets': u'1'} So, if one were relying solely on Nova to obtain information about this system's capabilities, the results would inaccurate results.
