I can confirm this and I am very dissapointed that still after more than a year this issue has not been fixed. I am currently running Ubuntu precise (development, the next lts) on HP DL 585 G2 with 4 Dual Cores and thus 4 Numa cells. Numactl shows the hardware: # numactl --show policy: default preferred node: current physcpubind: 0 1 2 3 4 5 6 7 cpubind: 0 1 2 3 nodebind: 0 1 2 3 membind: 0 1 2 3
virsh does not display the numa information: # virsh nodeinfo CPU model: x86_64 CPU(s): 8 CPU frequency: 1000 MHz CPU socket(s): 4 Core(s) per socket: 2 Thread(s) per core: 1 NUMA cell(s): 1 Memory size: 32948228 kB # virsh freecell 0 error: this function is not supported by the connection driver: NUMA memory information not available on this platform Just using numactl is no option if the guests are to be migrated. The numa-placement needs to be handled by libvirt! -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to libvirt in Ubuntu. https://bugs.launchpad.net/bugs/614322 Title: libvirt not recognizing NUMA architecture To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/614322/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
