$ numactl -c 1 -m 1 qemu-kvm -smp 2 -m 4G (pinning guest memory and cpus to numa-node 1)Ģ.For a single instance test, it would suggest trying a one to one mapping of vcpu to pyhsical core. If you want to pin other processes to numa node, you can use numctl and taskset.ġ.First level pinning would be to use numa pinning when starting the guest.Į.g. Assign 'numanode=-1' in tests.cfg, then vcpu threads/vhost_net threads/VM memory will be pined to last numa node. `iozone (windows) `_ (iozone has its own result analysis module)Īutotest already supports prepare environment for performance testing, guest/host need to be reboot for some configuration.Īutotest supports to numa pining.
