I realized that one of the NUMA API entry point didn't had a binding in Python, the enclosed patch adds it, it's a method on a virConnect class, taking the startCell and maxCells integer parameters and returning a list of available memory for that range of cell, using it should be as simple as launching python as root after reinstallation of the libvirt library and bindings and doing the following:
import libvirt conn = libvirt.open(None) conn.getCellsFreeMemory(0, 20)
it should return the array of available heap for each of the 20 first cells in machine, but I can't test this at the moment. Saori, Beth is there any chance you could test that patch ? thanks, Daniel -- Red Hat Virtualization group http://redhat.com/virtualization/ Daniel Veillard | virtualization library http://libvirt.org/ veillard@redhat.com | libxml GNOME XML XSLT toolkit http://xmlsoft.org/ http://veillard.com/ | Rpmfind RPM search engine http://rpmfind.net/
