For licensing reasons we can’t create VM’s that map each core as a separate socket.**** ** ** KVM and libvirt both support the ability to define the socket:core ratio/topology, but I can’t see how to get openstack to request those capabilities.**** ** ** I've tried the libvirt_cpu_mode and libvirt_cpu_model options, but they only seem to control the cpu's name, and what flags are passed through.**** ** ** It seems that if I could only get nova to create the xml file with a topology section eg: <toplogy sockets=’1’ cores=’4’ threads=’1’/> then it would work.**** ** ** This feature request seems related: https://bugs.launchpad.net/nova/+bug/1199019**** ** ** But I’m not sure if it’s possible to define it within nova as yet anyway.*** * ** ** Cheers, Evan.**** *Evan Fraser*** *Trade Me | Storage Engineer*** *P* *+64 4 803 2756***** *M* *+64 22 087 4032***** *E * *evan.fra...@trademe.co.nz* ** ** ** ** _______________________________________________ Mailing list: http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack Post to : openstack@lists.openstack.org Unsubscribe : http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack
