OpenStack配置虛擬機vcpu綁定步驟 轉至元數據結尾 1. Changed in compute node:給宿主機預留資源：宿主機可用cpu：cpuid 0 – cpuid 5宿主機可用內存：25G#vim /etc/nova/nova.conf vcpu_pin_set=6-31 reserved_host_memory_mb=25600#grubby --update-kernel=ALL --args="isolcpus=6-31" #reboot2. Changed in controller node:給nova-scheduler服務添加兩個過濾器，以過濾帶有vcpu綁定的計算節點出來，給用戶使用。這里的過濾是根據flavor的metadata中的aggregate_instance_extra_specs:pinned是true還是false，來判斷用戶是否需要給云主機做vcpu綁定。#vim /etc/nova/nova.conf scheduler_default_filters=...,NUMATopologyFilter,AggregateInstanceExtraSpecsFilter #systemctl restart openstack-nova-scheduler3. Configure aggregate:創建兩個機組，分別為不給云主機綁定vcpu的normal機組，和給云主機綁定vcpu的performance機組。并添加計算節點到各個機組中。10-0-192-21為normal機組host，10-0-192-20為performance機組。# nova aggregate-create performance # nova aggregate-create normal# nova aggregate-list +----+-------------+-------------------+ | Id | Name | Availability Zone | +----+-------------+-------------------+ | 6 | performance | - | | 9 | normal | - | +----+-------------+-------------------+# nova aggregate-set-metadata 6 pinned=true # nova aggregate-set-metadata 9 pinned=false# nova aggregate-add-host 9 10-0-192-21 Host 10-0-192-21 has been successfully added for aggregate 9 +----+--------+-------------------+---------------+----------------+ | Id | Name | Availability Zone | Hosts | Metadata | +----+--------+-------------------+---------------+----------------+ | 9 | normal | - | '10-0-192-21' | 'pinned=false' | +----+--------+-------------------+---------------+----------------+ # nova aggregate-add-host 6 10-0-192-20 Host 10-0-192-20 has been successfully added for aggregate 6 +----+-------------+-------------------+---------------+---------------+ | Id | Name | Availability Zone | Hosts | Metadata | +----+-------------+-------------------+---------------+---------------+ | 6 | performance | - | '10-0-192-20' | 'pinned=true' | +----+-------------+-------------------+---------------+---------------+4. Configure flavor: Add metadata 'aggregate type: normal' to old flavor:將已經存在的flavor的metadata的機組vcpu綁定屬性設置為不綁定： #for FLAVOR in ` nova flavor-list | cut -f 2 -d ' ' | grep [0-9]* | grep -v "\-\-" | grep -v ID`; do nova flavor-key ${FLAVOR} set "aggregate_instance_extra_specs:pinned"="false"; doneCreate new flavor with metadata 'aggregate type: performance':創建新的flavor， 帶有的metadata中vcpu綁定屬性設置為綁定： #nova flavor-create m1.big-1.vcpuPin 10 8192 20 4 #nova flavor-create m1.small.vcpuPin 11 4096 20 2... ... #for i in `nova flavor-list | grep vcpuPin | awk '{print $2}'`; do nova flavor-key $i set hw:cpu_policy=dedicated; nova flavor-key $i set aggregate_instance_extra_specs:pinned=true; doneLaunch an instance to test the new flavor, check if the instance runs in host whose aggegate type is performance:啟動一個虛擬機，使用新創建的flavor，驗證虛擬機是否運行在了10-0-192-20服務器上，檢查虛擬機的xml配置信息是否包含vcpu綁定配置： #nova boot --image ...Attention: 1. if flavor's metadata is NULL, then the vm may be scheduled to this pin=true host。 如果flavor的metadata為空， 即創建flavor的時候，不指定metadata的機組綁定屬性，則使用這個flavor的云主機可以像沒配置vcpu綁定的時候那樣， 運行在normal不綁定vcpu節點，或performance綁定vcpu節點。
