Hi, I observe that virsh capabilities give wrong cpu topology on a multiple sockets host taget@jfz1r04h13:~/libvirt$ lscpu Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 72 On-line CPU(s) list: 0-71 Thread(s) per core: 2 Core(s) per socket: 18 Socket(s): 2
ß---------------------- NUMA node(s): 2 Vendor ID: GenuineIntel CPU family: 6 Model: 63 Model name: Intel(R) Xeon(R) CPU E5-2699 v3 @ 2.30GHz Stepping: 2 CPU MHz: 1201.660 CPU max MHz: 3600.0000 CPU min MHz: 1200.0000 BogoMIPS: 4590.78 Virtualization: VT-x L1d cache: 32K L1i cache: 32K L2 cache: 256K L3 cache: 46080K NUMA node0 CPU(s): 0-17,36-53 NUMA node1 CPU(s): 18-35,54-71 But output of virsh capabilities only gives. <topology sockets='1' cores='18' threads='2'/> looking into code and got this: https://libvirt.org/git/?p=libvirt.git;a=blob;f=src/util/virhostcpu.c;h=f29f3122acee018b9fd7dca06fd7ae1fc118b210;hb=HEAD#l703 should we change it into 704 *sockets += nodesockets; This also affect nodeinfo.sockets. Attached file is the full output of capabilities of the host Best Regards Eli Qiao(乔立勇）OpenStack Core team OTC Intel. -- |
