如何在 openstack 中拥有节点亲和性？

0

例如，我有 3 台计算服务器，我想在每台服务器上都有 1 个特定实例，并且我想在它们上拥有节点关联性。

instance_1 --> compute_node_1（总是在这个节点上）
instance_2 --> compute_node_2（总是在这个节点上）
instance_3 --> compute_node_3（总是在这个节点上）

我知道有一个“森林”服务。但是具体如何使用呢？或者如果有其他解决方案？

如何在 Openstack 中使用没有存储磁盘的主机和没有本地驱动器的虚拟机实例

1

在 Openstack 中，是否可以创建没有硬盘驱动器的计算节点并使用 PXE 来启动主机系统，从而启动没有本地驱动器的实例来启动 VM 的映像。

如果不是，为了获得功能齐全的系统，需要为主机提供的最小存储空间是多少。

MySQL ERROR 1045 Access denied for 'nova'@'controller'

描述

我使用OpenStack 安装指南安装了 Openstack Wallaby ，所有命令和配置都在我的Github上。这个 LAB 在 VirtualBox 上运行，我在 ESXi 上有另一个具有相同配置和 Openstack 版本的 LAB，没有任何问题。

此时一个控制器带有两个计算节点。

在下一节中，改进正确配置的数据库权限

数据库已正确创建：

set @@global.max_connections = 400;
SET GLOBAL interactive_timeout=6000;
SET GLOBAL innodb_buffer_pool_size = 1024 * 1024 * 2;

任何尝试发现新主机都会导致以下错误：

Openstack 只为集群中的每台机器构建一个虚拟机，然后耗尽资源

1

我正在构建一个 openstack 集群，并且遇到了一些我认为可能是配额问题的问题。我可以在每台主机上成功构建虚拟机，但每台主机只有一个虚拟机。

我使用 puppet 部署了系统。当前部署的 openstack 版本是 Ussuri。使用的 openstack puppet 模块是 17.4，除了使用 13.4 的 puppet-vswitch

每个计算主机（管理程序）有 64 个内核和 512GB 的 RAM。即使我启动了一个 2 核 vm，我也无法在该虚拟机管理程序上再启动，并且我在日志中收到以下错误：

调度程序日志：

"status": 409, "title": "Conflict", "detail": "There was a conflict when trying to complete your request.\n\n Unable to allocate inventory: Unable to create allocation for 'VCPU' on resource provider

There are not enough hosts available.

我已经检查并重新检查了该项目的配额，并且实例数设置为 10000，所以我不确定我缺少什么：

| 固定IP | 10000
| 浮动_ips | 无
| 健康监视器 | 无
| 注入文件大小 | 10240
| 注入文件 | 5
| 注入路径大小 | 255
| 实例 | 10000
| 密钥对 | 100 | 项目名称 | 管理员
| 属性 | 128
| 公羊 | 99999999

我不太确定我还能检查什么，并且从我所做的搜索来看，似乎没有其他人遇到过这样的事情，所以我希望我缺少一个简单的设置。

编辑 5-26-21：我进行了更多测试，发现了一个有趣的模式。

如果我在计算主机上放置一台 1 核机器（风格 m1.nano），我可以构建任意数量的虚拟机，任何我想要的风格，直到机器物理运行资源。

如果我创建了大于 1 核 vm 的任何东西，并且该 vm 是在还没有 1 核 vm 的计算主机上启动的，那么在放置一台机器后，在该主机上构建的任何其他 vm 都会失败。

除了告诉我它在失败时无法分配 vcpus 之外，日志没有任何帮助。

编辑添加部署方法和 openstack 版本。

提前致谢！-杰夫

没有其他日志文件指示任何错误 syslog，dmesg也 /var/log/libvirt/libvirtd.log没有显示任何问题

libvirt 配置 ( /etc/libvirt/libvirtd.conf) 设置为记录错误 log_outputs="3:syslog:libvirtd"

在出现错误之前，节点运行平稳，没有进行任何更改。
