openstack虚机 cpu相关设置

在flavor里设置cpu绑定

nova flavor-key FLAVOR-NAME set \

 hw:cpu_sockets=FLAVOR-SOCKETS \

 hw:cpu_cores=FLAVOR-CORES \

 hw:cpu_threads=FLAVOR-THREADOCKETS \ 

 hw:cpu_max_sockets=FLAVOR-SOCKETS\

 hw:cpu_max_cores=FLAVOR-CORES \

 hw:cpu_max_threads=FLAVOR-THREAD

hw:numa_nodes=1 限制vcpu分配在一个numa上 一下是两个numa的分配配置

 
$ openstack flavor set m1.large --property hw:numa_nodes=2 $ openstack flavor set m1.large \  # configure guest node 0  --property hw:numa_cpus.0=0,1 \  --property hw:numa_mem.0=2048 $ openstack flavor set m1.large \  # configure guest node 1  --property hw:numa_cpus.1=2,3,4,5 \  --property hw:numa_mem.1=4096
设置cpu实时性
hw:cpu_realtime=yes
hw:cpu_realtime_mask=^0-1
hw:hypervclock=yes
