红帽全球峰会7.4.4. 其他参数
- NovaSchedulerDefaultFilters
- 提供有序的过滤器列表，计算节点用于为请求的客户机实例查找匹配的 Compute 节点。
- VhostuserSocketGroup
-
设置 vhost-user 套接字目录组。默认值为
qemu。*VhostuserSocketGroup*应设置为hugetlbfs，以便 ovs-vswitchd 和 qemu 进程可以访问用来配置 virtio-net 设备的共享巨页和 unix 套接字。此值特定于角色，应当应用到利用 OVS-DPDK 的任何角色。 - KernelArgs
在引导时为 Compute 节点提供多个内核参数。
根据您的配置添加以下内容：hugepagesz：设置 CPU 中巨页的大小。这个值可能因 CPU 硬件而异。为 OVS-DPDK 部署(默认_hugepagesz=1GB hugepagesz=1G )设置为 1G。检查pdpe1gbCPU 标记，以确保您的 CPU 支持 1G。lshw -class processor | grep pdpe1gb
lshw -class processor | grep pdpe1gbCopy to Clipboard Copied! Toggle word wrap Toggle overflow -
hugepages count：设置可用巨页的数量。这个值取决于可用的主机内存量。使用大多数可用内存（排除NovaReservedHostMemory）。您还必须配置与 Compute 节点关联的 OpenStack 类别中的巨页数值。 -
IOMMU: 对于 Intel CPU，添加"intel_iommu=on iommu=pt"' -
isolcpus：设置要调整的 CPU 内核。这个值与IsolCpusList匹配。
